Repair And Fix it

The Geo Metro is a compact car, manufactured by Chevrolet. Its diagnostic trouble code (DTC) 0705 can be identified by placing a fuse in the fuse box diagnostic terminal, located under the left-hand side of the instrument panel, and turning on the ignition.

Significance

Chevy Metro diagnostic trouble code 0705 represents a transmission range sensor circuit malfunction.

Check Engine Light

When the ignition is turned on, the check engine light will turn off if the code 0705 either does not exist or if it has been cleared. If the light stays lit, the code represents a problem. Data concerning the code is stored in the electronic control module (ECM).

Clearing the Code

Clear or erase the code 0705 in a Geo Metro by disconnecting the negative battery cable and isolating the battery ground cable for 60 seconds.

The Chevrolet 235 cubic-inch inline six-cylinder engine -- successor to the 216-cubic-inch -- entered full-production during the 1940s and continued until the 1960s. Identification requires locating and comparing the vehicle with 235 serial numbers. Any difficulty in identifying 235-cubic-inch engines is because other Chevrolet six-cylinder vehicles used the same block and the numbering system changed in 1954, requiring an alternative decoding process. If the serial number does not match any found on a listing, the stroke must be measured.

Instructions

1

Find the engine serial number. According to Old Car Manual Project, all 235-cubic-inch engine serial numbers are on the passengers side of the block, either near the oil dipstick or to the rear of the distributor. Pre-1954 engines have a two- to three-letter pix followed by a six-digit assembly number. Later engines begin with a seven-digit assembly number followed by the plant designation, model year and type designation; for example, 0123456 F 55 Z.

2

Decode the pre-1954 engine number. Old Car Manual Project decodes the example JAM 123456 as follows: "J" is the code for 1951. This year identification system began in 1941 with the letter "D" and continued in sequence until 1953 with the letter "L." The second letter, "A," is the vehicle designation and "M" is the plant code. The following six digits are the production sequence number. To decode the model designation and plant code, consult a listing similar to the one found on Old Car Manual Project. This listing has specific pixes identified as belonging to the 235-cubic-inch engine.

3

Decode the 1954 and later serial number. According to the website, 1954 and later serial numbers follow a different system, 0123456 F 54 Z, for example. The first set of numbers is the assembly sequence number, "F" is the plant designation, "54" is the 1954 year designation. The final set of letters -- in this case, "Z" -- are engineering codes. "Z" represents a standard 235 engine.

4

Remove the valve cover and the cylinder head to measure the stroke. Crank the engine until one of the pistons is at dead bottom. According to Museum Stuff, the 235-cubic-inch engine has a stroke measuring 3.9375 inches from the top of the piston to the top of the cylinder wall.

A Chevy exhaust gas recirculation (EGR) valve is a necessary part of the cars emissions system. It works by rerouting some of the exhaust gases back into the intake manifold rather than into the atmosphere.

Types

There are several types of EGR valves with the same function but different modes of operation. Older EGR valves are purely mechanical and run on vacuum; on many newer Chevrolet and other GM models, the valve is controlled entirely by computer. This type uses multiple solenoids to open the valve in response to input from the cars computer, opening and closing the valve to allow exhaust gas flow.

Operation

Whether the EGR valve uses vacuum or electronic control, it opens when exhaust gases reach a certain temperature or level of backpressure. When the EGR valve opens, some of the exhaust is rerouted to the intake manifold. Since it is less combustible than the air-fuel mixture in the manifold, the temperature drops.

Functions

The main function of an EGR valve is to lower the amount of nitrogen oxide a car releases into the atmosphere. A failed EGR valve prevents a car from passing emissions testing, if required. The valves secondary function is to lower the temperature in the intake manifold.

Suzuki markets the Suzuki Cultus under a variety of names, including the Chevrolet Metro, Geo Metro and Suzuki Swift. The engine for the 1998 Chevy Metro is a four-cylinder 1.3-liter engine with multiport fuel injection. This type of fuel injection requires the fuel pump to deliver fuel under high pressure. The fuel pump for the 1998 Chevy Metro is in the fuel tank, so you must remove the fuel tank when you replace the fuel pump.

Instructions

1

Open the cap for the fuel tank, and remove the control relay in the fuse box. Start the engine, and allow it to stall. Crank the engine for a few seconds to ensure no fuel remains in the fuel system. Disconnect the cable on the negative terminal of the battery with a socket wrench to ensure you dont accidentally start the engine.

2

Remove the rear seat cushion, and disconnect the electrical wiring for the fuel gauge in the bottom of the rear seat. Raise and support the vehicle on jack stands. Disconnect the fuel line from the fuel filter, and connect the open end of the fuel line to a hose. Siphon the fuel from the fuel tank into a gasoline container.

3

Disconnect the hoses for the fuel pipes on the fuel tank. Detach the fuel filler hose and breather hose from the fuel tank. Support the fuel tank with jack stands, and disconnect the mounting bolts for the fuel tank with a socket wrench. Lower the fuel tank from the vehicle.

4

Release the clamps for the fuel hoses to the fuel pump assembly. Remove the mounting screws for the fuel pump assembly with a socket wrench, and detach the electrical connector for the fuel pump. Lift the fuel pump assembly and gasket from the fuel tank.

5

Install the new fuel pump by reversing steps 1 through 4. Fill the fuel tank, and turn on the ignition to pressurize the fuel system. Start the engine, and check for fuel leaks.

The On-Board Diagnostics computer (OBD) in a 2006 Chevy has a maintenance light that turns on when your vehicle is ready for an oil change. You need to change the oil and manually reset the light. All you need to reset and turn off the light is a few moments of your time and your ignition key. Dont attempt to reset the light before you change the oil, as the computer wont be able to keep track of when your next oil change is due.

Instructions

1

Put the key in the ignition and turn it to "Run", but dont start the engine.

2

Push down on the accelerator three times within five seconds. Make sure you press the pedal all the way to the floor each time. Examine the instrument cluster to see if the engine oil light is flashing. Let it flash until it stops, probably in about ten seconds.

3

Turn off the vehicle and remove the key. Wait a minute, and then put the key back in the ignition and start the engine. Verify that the engine oil light has turned off. If it hasnt, repeat the process. You may have to press down harder and faster on the pedal.

Replacing the taillight bulbs in the taillight assemblies of your Chevy Silverado pickup will only take a few minutes and requires only simple hand tools to complete the job. The bulbs are housed within a plastic taillight assembly and the assembly requires removal from the truck to access the bulb. The 3057 bulbs used in the taillights of the Silverado are readily available from any parts store or most major department stores.

Instructions

1

Open the tailgate of your Silverado and locate the two taillight retaining screws on the inside edge of each taillight assembly. These are Phillips-head screws on the inner edge of the end of the cargo-bed wall, where the tailgate rests when closed.

2

Remove the two retaining screws with a Phillips screwdriver, setting the screws aside for reuse later. Grasp the taillight assembly and pull it straight out of the body until you can access the wiring harness connection on the back of the assembly.

3

Depress the locking tab on the connector and pull it off the taillight assembly. Grasp the socket on the back of the taillight, turn it counterclockwise -turn, and remove it from the assembly. Pull the failed bulb out of the socket and discard it.

4

Push a new bulb into the socket. Insert the bulb and socket into the rear of the taillight assembly and turn the assembly clockwise to lock it in place. Connect the wiring harness connector to the taillight assembly, pushing it in until it snaps in place.

5

Position the taillight assembly on the rear of the Silverado, making sure it seats completely; then install the two retaining screws. Tighten the screws with a Phillips screwdriver and close the tailgate.

If you have a Chevrolet car or truck made between 1967 and 1997, theres a good chance it has a 350-cubic-inch engine. The Chevrolet 350 small-block engine was offered in many Chevrolet cars and trucks and in other General Motors vehicles as well. The 350 became Chevrolets primary work-horse small-block engine after the demise of the 327 and 283 engines. The 350 is identified using both visual clues and casting numbers.

Instructions

1

Count the number of spark plugs. The 350 is an eight-cylinder engine

2

Inspect the engine compartment to locate identification tags. GM usually places various tags, decals and other identification devices throughout the engine compartment. These usually provide any necessary information if it is not worn off.

3

Locate the casting identification number on the engine block. This number is stamped on a pad just forward of the right-side (passengers side) cylinder head and may be hidden by the alternator. Remove the alternator if necessary. The ID number usually consists of eight digits in a combination of numbers and letters.

4

Decode the ID number according to Chevrolets code system. For example, the number V0908CNJ breaks down as follows: V is the engine plant, followed by the month and day of manufacture and the engine suffix code. ID number V0908CNJ was manufactured at the Flint engine plant on October 8 and was originally installed in a 1970 Caprice with 250 horsepower. To decode the engine suffix, cross-referencing is necessary.

Between the head and the engine block of a Chevy 350 resides a head gasket. The head gasket is a seal; it keeps the coolant that is moving from the engine block to the head from entering the combustion chambers of the motor. When a head gasket fails, coolant can enter the combustion chamber, which is a bad thing. Installing a new head gasket requires a special torque sequence to ensure the gasket seats properly against the head. Failing to follow the proper tightening sequence will result in the head gasket failing shortly after installation.

Instructions

1

Stand facing the head you are tightening.

2

Mark the top row of head bolts, using a wax marker, starting with the leftmost bolt. Mark that bolt 13. Mark the next bolt, moving to the right, 5. Mark the third one 2 and the fourth one 10. Move to the middle row of bolts and label them 17, 9, 1, 6 and 14 from left to right. Mark the lowest row of head bolts 16, 12, 8, 4, 3, 7, 11 and 15, left to right.

3

Attach a socket matching the size of your 350 Chevys head bolts to a torque wrench.

4

Set the torque wrench to 65 foot-pounds.

5

Tighten the head bolt marked number "1" with the torque wrench. Stop tightening the bolt when the torque wrench signifies the bolt has 65 foot-pounds of torque. Torque each bolt in the order they are numbered. For example, the next bolt you will torque is number "2," then number "3," until you reach bolt number 17.

6

Mark and tighten the bolts on the other head in the same manner as the first.

Some Chevy S-10 pickup trucks have problems with the tailgates. The tailgate cables ensure the tailgate stays at the correct level when it is in the down position. Weak cables may result in personal injury and damage to the truck.

History

The National Highway Traffic Safety Administration completed a defect investigation (EA05008) which details that owners of select Chevy S-10 trucks are authorized to have the cables replaced free of charge. The investigation also recommended that owners of Chevy S-10 trucks periodically inspect the cables for signs of wear and tear.

Warning

Cables that are worn or frayed can break unexpectedly. Moisture interacting with the cable reduces the strength of the cable. When the cable breaks, the tailgate can come down and hit the bumper. This can damage the bumper and tailgate cosmetically. A person may be injured if he is near or on the tailgate when the cable breaks.

Recommendation

Cables that appear to be worn, frayed or bulging should be brought to the attention of General Motors. A trained technician will be able to determine if the cables need to be replaced. Cables may be replaced free of charge if they are included in a warranty, safety notice or recall.

Chevrolet vehicles made in 1991 typically have an anti-lock braking system, or ABS, to improve the vehicles braking ability during an emergency stop. An electronic brake control module, or EBCM, monitors the rotation speed of each wheel. The EBCM decreases the braking force to a wheel when it detects that the wheel is rotating more slowly than the other wheels. The procedure for installing the EBCM is generally the same among many Chevrolet cars made from 1982 to 1994.

Instructions

1

Disconnect the cable from the negative battery terminal with a socket wrench. An electrical discharge from the battery can damage the EBCM when you remove it.

2

Unplug the electrical connectors from the EBCM. The EBCM is a small, box-like component mounted to the dash panel on the drivers side. It typically has two electrical connectors.

3

Remove the three hex head screws from the EBCM with a hex wrench. Detach the EBCM from the dash panel. Remove it from the vehicle.

4

Align the holes in the grommets on the new EBCM with the corresponding holes in the dash panel. Hold the EBCM to the dash panel.

5

Attach the hex head screws to the EBCM with a hex wrench. Torque the screws to 17 pound-feet with a torque wrench.

6

Attach the electrical connectors to the EBCM and connect the cable for the negative battery terminal with a socket wrench.

Repairing the backup lights on the rear of your 1998 Chevy Truck requires changing the bulbs. The backup lights provide clean, white light that allows you to see what is behind you when backing up the truck after dark. The lights also provide a way for other drivers to see you backing up. The bulb used in the backup lights of the Chevy is a 2057 and is available from parts retail stores.

Instructions

1

Open the tailgate of your Chevy and locate the two taillight retaining screws in the side of the bed where the tailgate would sit when closed. There is an upper and lower retaining screw on each taillight assembly.

2

Remove the retaining screws from the taillight assembly with a Phillips screwdriver. Pull the taillight assembly straight out of the body. Locate the electrical connector on the rear of the assembly, press the locking tab down, and disconnect it from the assembly.

3

Rotate the backup light bulb socket counterclockwise, and pull it out of the assembly. Pull the bulb straight out of the socket, and replace it with a new 2057 bulb. Slide the bulb socket into the rear of the assembly. Turn it clockwise to lock it in place.

4

Connect the electrical harness connector to the taillight assembly. Slide the assembly into the body opening. Install the two retaining screws through the body and into the taillight. Tighten the screws with a Phillips screwdriver.

5

Move to the opposite side of the truck and repeat the process if required. Close the tailgate.

You can turn off the seat belt chime on your 2005 Chevrolet yourself from your home garage. The chime is there to remind you that you need to fasten your belt, but many people find it very annoying. Just keep in mind that it is illegal to drive without your seat belt fastened in most states. So leave the chime intact if you live in one of these states, as turning off the chime wont allow you to use the seat belt.

Instructions

1

Call a junkyard and ask if they have any 2005 Chevrolet vehicles in your exact model. If they do, ask them if they have any seat belt assemblies. Some yards will remove the seat belt part for you, but you may have to do it yourself at others. If so, make sure you bring a Flathead screwdriver and a socket wrench set with you.

2

Cut the seat belt strap with scissors and remove the seat belt clip by sliding it from the seat belt strap.

3

Fasten the clip into the seat belt buckle on your vehicle. This will shut off the seat belt chime.

Todays vehicles use computers to monitor the functions of the vehicle. The 2002 Tahoes computer receives and stores trouble codes that, when read, will help you pinpoint the exact malfunction. After having the codes read and the vehicle serviced or repaired, you will need to reset the codes. If you dont want to spend the money on an OBD-II scan tool, you can make the adjustment from home using and adjustable wrench.

Instructions

1

Park the vehicle and turn off the ignition. Pop up and secure the vehicles hood and find the battery.

2

Loosen the nut on the negative battery cable with the adjustable wrench. The negative cable is black and marked with a "-" sign. Slip the clamp off of the negative battery terminal and do not to let it touch anything metal, especially the positive battery terminal.

3

Wait 30 minutes while the Tahoes computer resets.

4

Put the negative battery cable back in place and tighten the nut with the adjustable wrench.

5

Put the key into the ignition and start the vehicles engine. Verify all warning and service lights have shut off. Drive the vehicle. It will take a few trips for the computer to reset and get in sync with all of the vehicles functions.

Chevy generally places the hood release cable under the dash panel, between the steering column and the left side kick panel. The hood release cable on a Chevy Caprice is made of a thin metal wire cable running through the center of plastic housing. The cable has a loop on it to hook to the hood latch. The hood latch is located under the hood in the front of your vehicle.

Instructions

Remove the Broken Cable

1

You will need to cut the broken cable to release the hood. You can access the release cable from under the dashboard. Cut the cable housing where it becomes 1/4-inch round. Find the wire cable inside the housing and pull it. The hood will likely release at this point, but if it does not then you will need to access the release cable under the bumper.

2

Locate the release cable by running your hand behind the bumper, or visibly spotting the latch. Locate where the release cable hooks to the latch. Take a heavy wire and put a loop in it. Hook the loop to the latch where the release cable is hooked. Pull the wire to release the hood.

3

Release the safety latch, which is located in the center of the vehicle above the grill. Push it aside and raise the hood. Remove the release cable from the hood latch and pull through the firewall. Take off the release handle from inside the vehicle, under the dash, by removing the two Phillips screws.

Installing the New Release Cable

4




Thread the new release cable through the grommet hole in the firewall and reattach the handle to the bottom of the dashboard with the two Philips screws removed earlier.

5

Replace the release cable by routing it back to where it was before and hooking the cable end with the loop onto the hood latch release lever.

6

Lube all the moving parts on the hood latch with white lithium grease and clean up all the overspray.

Chevrolet introduced the Nova sports car in 1962. The alignment specs were the same for all trims of the 1966 Chevy Nova. The alignment was not adjustable on the rear end because the Nova came with a fixed rear axle.

Caster

The caster angle is the measurement, in degrees, of how far a line drawn through a wheels steering knuckle is inclined from a vertical line through the center of the wheel. The ideal caster for the 1966 Nova is +1.0 degree, but it can range from +0.5 to +1.5 degrees.

Camber

Camber is the angle at which the top of a wheel tilts when viewed from the front of the vehicle. Tilting out is positive camber, and tilting in is negative camber. The ideal camber for the 1966 Nova is +0.5 degrees, but it can range from zero to +1.0 degree.

Toe-In

Toe, when measured in inches, is the difference in the distances between the centers of the fronts and the rears of the front wheels. Most vehicles are designed to toe-in, meaning the distance between the fronts of the two front wheels will be slightly less than that of the backs of the two front wheels. The toe-in for the 1966 Nova can range from 1/4 of an inch to 3/8 of an inch.

The Chevy 350 Vortec engine is found in different models of trucks. If you cant get your 350 to start, there are a few things that you can look at before you take it to a mechanic. The battery is the most common issue with motors that wont start. If the battery is dead or even has a low charge, the motor will not be able to turn over. Checking the fuel level, the alternator, and the starter is also recommended.

Instructions

1

Turn the ignition on your vehicle. Listen for a clicking noise. If you hear a clicking noise, get your car or truck to a mechanic to test the alternator or the starter. Mechanics have specialized tools for this.

2

Look for the gauges to turn over when you turn the ignition. If the gauges flicker on, you are low on fuel. Fill the fuel tank and start your car.

3

Pop the hood and locate the battery. The battery will have two terminals coming to it. Get a socket wrench or a pair of pliers and remove the terminals from the battery.

4

Use a can of soda and a wire bristled brush to clean the terminals. Reattach the terminals and start your car.

5

Jump start your car with jumper cables and another vehicle. Let the car run for about 5 minutes to charge the battery. Cut the car off. If the car will not come back on, replace your battery.

A properly working door handle makes for an important part of your Chevy S-10 if you do not want to get into your truck like a "Dukes of Hazzard" television star. The metal used to manufacturer the brackets on the door handle, known as "pop steel," is a relatively soft metal usually used on low-wear items. Over time, however, the brackets can become weak and eventually break.

Instructions

1

Open the door, and remove the screws that secure the inner door panel to the sheet metal on the inner door with a screwdriver.

2

Pull on the upper left corner of the door to loosen the door panel from the sheet metal. Small plastic tabs connect the door panel with the sheet metal about every 10 inches. As you pull on the panel, pull the tabs out of the sheet metal.

3

Locate the back of the door handle by looking through the upper holes in the sheet metal. On the left side of the door handle, youll see a long bar connected to a piece of metal on the side of the handle. The bar moves when you lift up on the handle and opens the door latch.

4

Remove the metal bar from the left side of the handle by pulling the bar to the left. (The bar is not attached with bolts.)

5

Lift up on the handle from the outside door, and remove the two bolts located under the handle with wrenches. The bolts secure the handle to the sheet metal on the outside of the door.

6

Pull the handle out of the door.

Coil springs provide absorption for varied road conditions, allowing a vehicle to have a smooth ride. When the springs are compressed for prolonged periods of time, they eventually lose their original length, causing the ride to suffer. Replacing the front springs on a 1988 Chevrolet Camaro requires a few specialized tools and should only be done by experienced mechanics.

Instructions

1

Place blocks under the rear wheels so the prevent the vehicle from rolling when raised. Lift the vehicle with a hydraulic lift and place the two jack stands under chassis structural points behind the front wheels. This will cause the front wheels to sag due to the pressure of the coil springs and shocks. Lower the lift and reposition it under the control arm. Lift until the wheel is raised to is normal position.

2

Remove the lugs using a 1/2-in. ratchet wrench and socket lug. Place the lugs in the wheel and slide the wheel underneath the vehicle for extra safety. Use the appropriate sized Allen wrench to remove the retainer bolts for the brake caliper. Remove the caliper and and place it on a box or brick to prevent it from pulling the brake line. Locate the wheel hub assembly and remove the two bolts located on the flange of the lower and upper control arms. Remove the hub assembly and place to the side.

3

Use the 1/2-in. ratchet wrench and appropriate-sized socket to remove the front shock. Pull the shock away from the control arms and place to the side. Slowly lower the hydraulic lift under the lower control arm to allow the spring to release compression tension.

4

Remove the lift and place the coil spring compression tool inside the coil spring. Adjust the tool arms to grip on the spring and tighten the compression bolt with an adjustable crescent wrench.Tighten the compression tool until the spring can be removed from the control arm mounts. Slowly loosen the compression tool to remove it from the spring. Installation of the new spring is opposite of removal.

Underneath the timing cover of a small-block Chevrolet engine sits the timing chain and gears. Most often this cover is removed in order to replace the timing chain, but it is also part of the disassembly when rebuilding a small Chevy V8. Though the timing cover sits on the front of the motor, it is obscured by other engine components mounted in front. To remove the timing cover, these obstacles must be removed first.

Instructions

1

Drain the engine coolant and engine oil. On some Chevy models, the oil pan will also need to be removed in order to take off the timing cover.

2

Remove the bottom radiator hose by loosening the screw clamp with a flat screwdriver, draining the coolant into the waste bucket. The bottom hose is the one that hooks to the water pump. If the top hose and radiator are in the way, they will need to be removed as well.

3

Take off the cooling fan and then remove the drive belts.

4

Remove the water pump. Allow the excess fluid to drain from the block into the waste bucket.

5

Remove the harmonic balancer with a harmonic balance puller. Do not pull on the edges of the harmonic balancer or it will separate the rubber from the metal housing.

6

Take off any additional brackets that may be in the way.

7

Disconnect the engine mounts if the engine needs to be raised in order to access the timing cover.

8

Remove the bolts on the timing cover and pull the cover loose. If you did not take off the oil pan, then open the timing cover slightly and tilt it back. Cut the front oil seal off evenly with the engine. Remove the cover.

Replacing the alternator in your Chevy truck may become necessary if the original quits or starts to show signs or failure. If you are not sure that the alternator is failing, removing it from the truck will allow you to bench-test the unit and determine without question if that is where your issue lies. If the alternator is faulty, replace it with a new or remanufactured unit, available from any auto-parts store or through the Chevy dealers parts department.

Instructions

1

Remove the retaining bolt from the negative battery cable end with a wrench, then remove the cable from the negative battery terminal. Isolate the cable from the battery by setting it off to the side where it cannot fall back against the battery.

2

Place a socket and breaker bar on the axis bolt in the center of the serpentine belt tensioner pulley. Rotate the tensioner counterclockwise and then slide the belt off the alternator pulley.

3

Locate the electrical connections on the rear of the alternator. Remove the nut from the "B" terminal with a wrench, then slide the battery cable off the terminal. Disconnect the plug in the connector from the body of the alternator by pressing the locking tab, then pulling the connector out of the alternator body.

4

Locate the two mounting bolts at the bottom of the alternator. Remove both bolts using a socket and ratchet, then lift the alternator off the bracket. Position a new alternator onto the mounting bracket, install the two mounting bolts and torque them to 37 foot-pounds with a torque wrench.

5

Install the electrical connections on the rear of the alternator. Plug the push-in connection to the socket on the alternator body and install the battery cable onto the "B" terminal. Torque the nut to 13 foot-pounds with a torque wrench.
