Repair And Fix it

The Chrysler Pacifica is a mid-size car that was manufactured from 2004 to 2008. You can remove the seat back from your Chrysler Pacifica from your home garage, saving yourself time and money. You only need one tool to do the job that can be purchased at a hardware or auto parts store. It will take you about 30 minutes to complete the job. The reason most people remove the backseat is to reupholster it. Sometimes, though, the floor carpet may need to be replaced or cleaned.

Instructions

1

Pull the front seats as far forward as possible. Open both rear doors. Pull up and forward on the rear drivers side front of the seat cushion in the backseat and remove it from the vehicle. Do the same for the other seat cushion.

2

Remove the nuts from both of the mounts on the backseat using a socket wrench.

3

Move the seat belt mount away from the mount on the backseat.

4

Push up on the middle part of the backseat. Pull it forward to release it from the hooks. Remove the backseat from the vehicle.

The cylinder heads in the four-stroke combustion engine have valves and valve seats that must be machined to precise tolerance and fit. If the valves do not seat correctly with their seats, they leak and lose compression. Valves that do not match within specifications with their seats can also cause excessive overheating and valve failure. The valve seat takes a continual pounding from the action of the valve when it closes. Valve seats can crack and become worn. Several tools need to be used to check and repair valve seats.

Crack Checking Tools

Before any valve seat can be reshaped and ground within specifications, the vale seat area must be magnafluxed to reveal hairline cracks. An electrical transformer attaches to the head, where it delivers a a high voltage magnetic charge to the metal. Magnaflux, which consists of a powdered, reactive chemical, gets sprinkled on the valve seat area. The chemical power reacts to breaks in the magnetic lines of force (field), which shows up as horizontal lines or spider-webbing cracks in the metal.

Valve Seat Grinding Machine

The valve seat grinding machine consists of of a platform vice that holds the cylinder head in a fixed and upright position. The vice fasteners lock the head into a level and stable orientation. The overhead part of the valve seat grinder consists of a motor that drives a cutting bit, which can be adapted to cut out the old valve seat from either aluminum or cast iron. A machine bit then cuts the new valve seat face at a precise angle, usually around 45 degrees. Dial indicators determine the depth of the cut, while bits determine the seat diameter to be cut. Lubricant, fed by the machine, keeps the cutting surface cool.

Valve Lappers

Valve lapping tools must be used to attain final sizing of the face and valve seats for a perfect, sealed match. The most common valve lappers consists of wood dowels that have two different size suction cups on each end. After the valve has been inserted in the stem and abrasive compound has been brushed between the valve face and the seat, a manual twisting motion turns the wood dowel back and forth to cut the interface seat between the valve and seat. Valve lappers come in a variety of suction cup diameters for intake and exhaust valves of all sizes.

Motorized Valve Lappers

Instead of manual wood dowel lappers, motorized drills and air guns can be fitted with suction cup bits that attach to the top of the valve. Once abrasive lapping compound has been applied between the valve and seat, the motor or air tool is turned on to spin the valve at high rpm. The use of power tools for lapping reduces the labor time involved in cutting the final seat and valve face.

Valve Seat Grinding Compound

Valve seat grinding compound consists of a a thick paste that contains cutting abrasives. The cutting compound comes in fine, medium and coarse grits. The coarse grit takes the most of the irregularities and burs out of the interface surfaces, while the medium and fine cutting compound cuts the last finishing face between the valve and valve seat.

The Volvo 850 is a compact car produced by the Swedish auto maker between 1992 and 1997. You can remove the seats from a Volvo 850 at home, saving yourself some money on labor. The upholstery on the 850 tends to crack and wear out quickly, thus requiring removal for re-upholstery. You only need a few simple tools to complete this job. It should only take about an hour to remove all the seats from the vehicle.

Instructions

1

Pry up the plastic caps on the side rails on the front doors using a flathead screwdriver. Remove the screws underneath the plastic caps using a Phillips-head screwdriver.

2

Locate the two rail caps at the bottom rear of each front seat. Slide the caps off the rails by hand. Find the four bolts on each of the seat rails and remove them with a socket wrench.

3

Slide the front seats back on the rails and lift them up and out of the vehicle.

4

Lift up and forward on the rear seat cushion to remove it from the vehicle.

5

Release the latches near the rear-seat headrests using a flathead screwdriver. Pull the seat backs out of the vehicle.

The Ford Mustang was introduced in 1964. The 1994 Ford Mustang was available in GT and Cobra trim levels. The GT variant was equipped with a 3.8-liter V-6 capable of producing 145-horsepower. The famous 5.0-liter V-8 was optional for 1994 Mustang GT, and could produce 215 horsepower. Removing or replacing the seat belt panel on the 1994 Mustang GT requires work on the body of the vehicle. This project should be carried out by someone with prior mechanical knowledge. Removing the seat belt panel involves the removal of a safety device, which should be re-installed by a professional mechanic.

Instructions

1

Open the door of the Mustang. Slide the seat as far forward as it can go, then release the back of the seat to tilt it forward. Locate and remove the two screw caps on the vertical door rail, near the door catch, using a flat-head screwdriver. Remove the two bolts beneath the caps with a ratchet and socket.

2

Push the front edge of the back seat back and release it from the clips. Pull the front lip of the seat upwards -- you may have to get in on both sides of the car and use your knee to push the seat back, to release the clips. Tilt the front of the seat up and remove the back seat from the Mustang.

3

Remove the cover from the speaker on the seat belt panel by gently prying it off with a flat-head screwdriver. Remove the three Philips screws that hold the speaker to the panel. Pull the speaker out of the panel, and pull the speaker wires free from the back of the speaker, by hand. Set the speaker out of your work area.

4

Remove the 15-mm bolt from the base of the seat belt panel, using a ratchet and socket. Allow the bottom of the belt to retract through the slot in the panel. Gently pry the panel loose from the side of the Mustang, using a putty knife wrapped in a towel. Slide the putty knife along the edges until you hit a clip, then pry the panel free from that clip -- the rest of the panel is held on by multiple body clips. Pry the panel free from all of the clips, then remove the panel from the Mustang.

5

Install the panel into the car, and align the panel with the clips underneath. Gently tap the panel with the side of your fist or a rubber mallet, starting in the center-rear of the panel. Pull the bottom of the seat belt through the panel, then install the seat belt mounting bolt in the floor, by hand. Turn the bolt a couple of threads to temporarily hold the belt in place.

6

Tap the edges of the panel to install the panel on the rest of the body clips. Tighten the seat belt mounting bolt back into the bottom of the seat deck, using a 1/2-inch drive torque wrench and socket. Tighten the bolt between 25 and 34 foot-pounds. Install the speaker wires back onto the rear speaker. Insert the speaker into the panel and tighten the screws snug with a Phillips screwdriver -- no torque is needed on the speaker screws; adding torque can crack the panel.

7

Install the rear side of the back seat under the vertical seat cushion. Push the front edge of the seat back and down to clip it into the floor of the car -- you may have to enter both sides of the vehicle and use your knee to push the seat back enough to engage the clips. Lift up on the front lip of the seat with your fingers to make sure that you have the seat clipped in. Repeat this step until both sides of the back seat are securely fastened.

8

Install the two screws into the panel near the door catch, on the vertical door jamb. Tighten the screws snug with a ratchet and socket. Install the screw caps.
