Repair And Fix it

The exhaust system in your vehicle is attached at various points along the vehicles frame. The system uses an assortment of clamps and hangers to support the exhaust components, as well as to isolate them from excessive vibration. A failure of any of the clamps or hangers will result in the movement of the exhaust system, which will be felt by the driver as vibration. This can often be heard as buzzing noise from underneath the car.

Instructions

1

Lift the vehicle with the jack and place it on the jack stands.

2

Inspect the exhaust hangers and clamps. Look for any cracking or looseness.

3

Tighten any loose clamps or hangers by turning the mounting bolts clockwise with the wrench.

4

Replace any clamps or hangers that appear damaged in any way.

5

Raise the vehicle from the jack stands and remove them. Lower the vehicle to the ground.

Throttle linkages are made in three basic configurations. Mechanical, or "bell-crank," systems are among the oldest and utilize system of levers and rods to link the gas pedal to the throttle. Cable systems that rely on a metal cable sliding within a flexible sleeve have largely replaced bell-crank mechanisms, which have always been prone to squeaks, rattles and hanging up. Electronic "drive-by-wire" throttles are gaining a foothold in the automotive industry but have yet to supplant the reliable cable. You can install a throttle cable in your driveway or garage.

Instructions

1

Crawl under the dashboard and locate the hole in the firewall through which your throttle cable will pass. Its typically located just above the gas pedal. Grasp the engine-end of the throttle cable and push it through the hole into the engine compartment, and continue feeding it through until the mounting flange on the sleeve hits the firewall.

2

Install the bolts that retain the sleeve mount to the firewall and hand-tighten them. Open the hood and reach into the engine bay to pull the cable up; lay it on top of the engine but do not connect it yet. Go back inside the car and pull the end of the cable over the forked split in the top of your gas pedal. Tighten the nut to clamp the cable to the gas pedal. Pull the pedal all the way up.

3

Install the engine-end of the throttle cable into the lever arm on your carburetor or throttle body. The procedure will vary by the type of engine. Some cables have a cylindrical piece on the end that locks into a slot in the throttle lever. For these types, pull the throttle lever all the way back, insert the cylinder into the recess on the side of the lever and feed the cable through the slot. If your throttle uses a retainer, push the throttle tip into the appropriate hole on the lever arm, then slide the retainer into the groove on the throttle tip to hold it in place.

4

Push the retainer on the end of the sleeve down into the retaining fork on the throttle cable bracket. Some applications have provisions for adjustment. If so, turn the adjuster nut on the sleeve until the cable is taut but not pulling on the throttle arm. Other applications dont use a forked throttle bracket; in these cases, feed the throttle cable through the hole in the bracket before connecting it to the throttle. Adjust the cable afterward.

The Mitsubishi Eclipse is a two-door coupe or convertible, and is also sold as the Eagle Talon and Plymouth Laser. It has been available in the United States since 1990, and the second generation of the Eclipse includes the 1995 through 1999 models. The timing belt is mounted on the crankshaft pulley and camshaft pulley, allowing the crankshaft to drive the camshaft. The removal procedure for the crankshaft pulley in a 1997 Eclipse also requires you to lift the engine in some cases.

Instructions

1

Disconnect the cable from the negative battery terminal with a socket wrench. This prevents anyone from starting the engine during the crankshaft pulley removal.

2

Remove the undercover for the engine with a socket wrench to gain access to the crankshaft pulley.

3

Raise the engine slightly with an engine hoist to remove some of the weight from the side engine mounts, and hold the engine in this position. Perform this step only if your 1997 Eclipse has a turbocharged engine or a 2.4-liter engine.

4

Disconnect the bracket for the engine side mount with a socket wrench to access the crankshaft pulley. Detach the accessory drive belts from the crankshaft pulley.

5

Disconnect the mounting bolt for the crankshaft pulley with a socket wrench. Remove the crankshaft pulley from the crankshaft.

Intake gaskets seal gaps between the intake manifold and the cylinder head. They are made in thicknesses ranging from 0.060 inch to 0.120 inch. If too much air gets into the system, the car will not run properly.

Intake Manifold

Gaskets are located throughout the engine, but one of the most important parts of the engine is the intake manifold. The intake manifold regulates the amount of air and fuel your engine gets to create the combustible reactions that power the business. The gaskets can withstand temperatures of 500 degrees Fahrenheit and higher. Some gaskets are made from high-temperature plastic that actually cools the air that passes through them.

Gasket Problem Symptoms

You know that your intake gaskets are no longer doing their job if you start seeing puddles forming under the car when it is in park or when you see a leak in the coolant system. Also, if your engine is rough and slightly jerky, or if you hear whistling from the engine taking in excess air, you have problems with your gaskets.

Repair

A vacuum gauge that checks manifold pressure is used to find the leak. All coolant must be drained from the vehicle and the manifold must be removed in order to replace the gaskets.

Warning

In the book, "Small Black Chevy Engine Buildups," the editors write that with too much air "your engine will turn into melted cheesecake; too little and itll drive like melted cheesecake."

The oil pan or oil level sensor in your Mazda MPV monitors the amount of oil in the oil pan. The sensor has an electrical connection that enables it to communicate with the PCM (power control module). When the oil level reaches or falls beneath the sensor, it illuminates the oil light in your MPVs dash cluster. Damage to the oil level sensor most often results from electrical failure. You can located and replace the oil pan sensor on your 1990 Mazda MPV right at home. The job should take you approximately 30 minutes.

Instructions

1

Place a wheel block firmly into position behind both of your MPVs rear tires.

2

Apply the emergency brake and raise the front end of your vehicle with a hydraulic jack. The bottom of both of the front tires should visibly measure no more than 8 inches from the ground.

3

Set a jack stand behind the front tires underneath your MPVs frame rail. Lift the support arms on both jack stands to 85 percent of the height of the hydraulic jack.

4

Lower the hydraulic jack slowly while you monitor both of the jack stands. When you see that your MPV securely rests on the support arms of the jack stands, stop lowering the hydraulic jack. Do not completely remove or lower the hydraulic jack. Leave it in its position for extra support.

5

Slide under your Mazda MPV and locate its oil pan. The oil pan sits at the lower, rear of the engine. It looks like a black, metal rectangle and has 20 small bolts around its upper lip. The oil pan also has a large bolt at the bottom of it used to drain the oil.

6

Locate the oil pan sensor on the lower side of your oil pan. You will not be able to see the sensors length but you should see the wiring harness connected to the top of it. On some models of the 1990 Mazda MPV, the sensor mounts just above the oil draining bolt. On other models, the sensor mounts on the opposite side of the oil pan across from the oil draining bolt.

The Honda XL 500s was in production for 1979 through 1981. A good motorcycle, it boasts 65 mpg fuel economy with top speeds around 146 kilometers per hour. Changing the oil in the vehicle is simple and has two options for capacities.

Without Filter

The oil capacity for the XL500s without a filter change is 1.3 liters of a recommended SAE 10W-40 oil.

With Filter Change

With a filter change, the capacity increases to 1.5 liters of the same oil weight.

Recommendations

Change the oil frequently, as the motorcycles intended use is off-road. Off-road vehicles gather more dust and debris into the engine compartment, which poses a hazard to the operation of the engine. While draining out the oil and not replacing the filter is a quick and easy option, you should change the filter each time to prolong the life of your engine.

The EX500 carburetor is used to bring the right mix of air and fuel into a car engine. When a carb isnt working, the engine will either die or it will take in too much fuel. The EX500 will make the engine run again, but it will also cut down on fuel intake. You dont have to be a mechanic to install the carburetor; you can do it yourself.

Instructions

1

Pop the hood on your car and locate where the carburetor should be installed next to the engine. Clean the intake manifold on the top of the carburetors gasket surface with a rag. Remove the old carburetors gasket with a razor blade.

2

Put the EX500s gasket over the four studs where the carburetor will be installed. Place the EX500 over the four studs and then place it over the gasket.

3

Connect the four retaining nuts over the studs on the corners of the carburetor. Tighten the nuts with a socket wrench. Apply the gasket glue to the gasket and allow it to dry. This should take about four minutes.

4

Put the small hose clamp over the end of the cars fuel line. Connect the fuel line to the fuel inlet on the carburetor. This is on the right side of the carburetor. Slide the larger hose onto the fuel line and then tighten the clamp with a screwdriver.

5

Connect the throttle cable to the cars throttle linkage. This is located on the right side of the carb. Connect the distributor vacuum line to the inlet on your carb. Turn on the car.
