BMW based its 7 series of cars, made from 1994 to 2001, on its E38 platform. The 740I --- the most popular vehicle in the series --- featured an eight-cylinder, 4.4-liter engine. All of the engines in this series use fuel injection, which requires a fuel injector to deliver fuel to the engines at high pressure. The fuel injectors for the E38 incidents are part of the fuel rail assembly on top of the engine.

Instructions

1

Remove the upper intake manifold with a socket wrench and detach the electrical connectors for the fuel injectors. Disconnect the vacuum hose on the front of the fuel rail.

2

Attach a pair of locking pliers to the adjustment screws on the hose clamps for the fuel return line on the fuel rail. Turn the screws counterclockwise to loosen the clamps and disconnect the fuel return line from the fuel rail. Remove the flare nut on the fuel line with a 12-millimeter socket and disconnect the fuel line from the fuel rail.

3

Spray compressed air around the base of the fuel injectors to keep debris out of the injector ports. Remove the mounting bolts for the fuel rail with a 10-millimeter socket.

4

Pad the corner of the valve cover with a clean shop towel and pry the fuel rail with a small pry tool to lift the injectors out of the manifold. Push the fuel lines to the side and remove the fuel rail assembly from the engine.

5

Pull the fuel injectors from the fuel rail assembly and connect the new fuel injectors. Install the fuel rail assembly to the engine and fasten the mounting bolts for the fuel rail.

6

Connect the fuel line to the fuel rail with the flare nut. Connect the fuel return line to the fuel rail by attaching the hose clamps and fasten the retaining screws on the clamps.

7

Connect the vacuum hose to the front of the fuel rail and attach the electrical connectors to the fuel injectors. Replace the upper intake manifold with a socket wrench.

The exhaust manifold collects the exhaust from all of the cylinders and channels it away from the engine through the exhaust pipe. An exhaust manifold that is cracked will no longer work efficiently and you will need to replace it. Leaking exhaust exposes anyone riding in the car to carbon monoxide fumes as well. It does not take very long to replace the exhaust manifold on a Ford. You can do the job yourself in your driveway with some basic tools.

Adjust the emergency brake on your Mustang right from your home garage and save money. You can adjust it from inside the car so you dont have to get yourself dirty by working under the car. Is time to adjust the parking brake when you park downhill and the parking brake starts to slip. This means that the parking brake cable has slackened inside the cable rod and needs to be tightened with the adjuster nut. Tension put on the emergency brake over time causes the parking brake to slip.

Instructions

1

Locate the parking brake in the front center of the inside of the vehicle. Remove the console cover that houses it.

2

Lift up the emergency brake lever four notches.

Look for the parking brake cable rod. On this rod is an adjuster nut. Turn that nut with the pliers until it is loose but make sure it doesnt fall off all the way.

4

Release the parking brake and tighten the nut.

5

Raise and lower the emergency brake lever four times. This will set the adjustment of the parking brake.

6

Park the Mustang on a downhill slant and engage the parking brake only. It should hold the vehicle in place. If it doesnt, repeat the adjustment.

A cars fuel injection system supplies fuel to the engine. In order to get optimum performance from your vehicle, the fuel must flow at a steady pressure. Regulators control the fuel flow, making sure it is consistent. Like other mechanical parts, regulators can break down and require replacement. Symptoms of a faulty regulator include lower gas mileage, excess smoke from exhaust pipes and leaking oil from the engine. Replacing a fuel regulator can be a difficult task for inexperienced owners, but if you have basic car repair experience, you can save money and replace it yourself.

Instructions

1

Relieve the pressure in the fuel tank by opening the gas cap. Open the hood of the car and separate the cable from the negative battery terminal. Pull out the cushion on the rear seat. Remove the screws on the service hole cover and take off the cover.

2

Disconnect the electrical wiring from the fuel pump assembly. Use the fuel line disconnect tool to unplug the fuel outlet pipe from the fuel pump bracket. Unscrew the retaining screws for the fuel pump bracket with the socket wrench. Pull off the return hoses from the bracket. Take the assembly out of the fuel tank.

3

Use the socket wrench to remove the fuel suction support from the fuel pressure regulator. Separate the fuel filter from the regulator. Find and remove the O-ring from the regulator.

4

Apply a thin coating of gasoline to the O-ring and insert it into the new fuel pressure regulator. Attach the regulator to the fuel filter. Connect the fuel suction support to the regulator using the wrench.

5

Replace the fuel pump assembly in the fuel tank and reconnect the hoses to the fuel pump bracket. Attach the retaining screws to the fuel pump bracket and connect the fuel outlet pipe to the fuel pump bracket.

6

Reattach the wiring for the fuel pump assembly. Reinstall the service hole cover with the socket wrench. Reinstall the rear seat cushion and reconnect the negative battery cable.

Its a good idea to proceed with caution before agreeing to car repairs at a garage. Take a few days to compare garages to decide which car garage is the best for you.

Family and Friends

Many car owners have a trusted mechanic they turn to for repairs, but if the work needed on the car is outside the mechanics specialty, ask for a erral. Aside from your mechanic, ask family members or friends if they know of a good car garage. Chances are good someone you know has had to have their car repaired at a garage. They can offer some pointers on where to get the best deal.

Insurance Providers

Your insurance provider often has information on good car garages. Many car garages leave their business cards and information with car insurance companies because its the best way for them to get more business. Additionally, these garages must meet high standards and have certification before they are a business car insurance companies are willing to recommend.

Compare Estimates

Most car garages will provide you with a free estimate. Make sure you get a detailed list of estimates. Dont be surprised if the part you end up buying at the garage cost more than it would at an auto parts store.

Customer Service

Do the staff and mechanics act professional? Do they treat you with courtesy? Do they get work done on time? Do they work well together? How garage staff treat you now is not likely to change once you are their customer. Pay attention to how you feel being in this place of business and how others act toward you. If the mechanic is rude or the counter person would rather text instead of assisting you, take your business elsewhere.

Personnel and Credentials

Some car repair requires work done by a certified mechanic or a specialist. Some garages may have these mechanics, some may not. Make sure the garage is candid about what kind of repairs need to be done on your car and whether they have the right mechanics for the job. The better garage to go with is the one that has the kind of mechanic youll need for your car repair.

Years ago in the days of R12 rigerant, when an air-conditioning service port went bad on your automobile, a Schrader valve could simply be serviced by itself. In todays 134A world, things have gotten a bit more complicated and costly. You cannot just replace the inside of a Schrader valve; now you have to replace the entire line where the port is located.

Instructions

1

Connect either the high side or low side hose on an A/C servicing station to the appropriate service port. Do not connect a line from the air-conditioning servicing station to the defective port. Evacuate the R134a rigerant into the rigerant tank on the air-conditioning station by turning on the evacuation pump and running it until all the rigerant has left the system.

2

Disconnect both ends of the line with the defective service port and remove the line. Cover the connections on the A/C system with clean shop rags to prevent dirt and moisture from getting into the A/C system.

3

Inspect the connections for discoloration. If the connections are clean and slightly oily there are probably no other problems that caused the service port to go bad. Blackened connections could be a sign of internal compressor problems. Investigate further and perform any necessary repairs.

4

Connect the ends of the replacement line with the built-in service port just as the old line was connected. Ensure that any O-rings or seals at the ends of the lines are replaced and lubricated with mineral oil before the new line is installed.

5

Connect the other hose from the A/C servicing station to the replacement port. Start the evacuation pump and run it for 15 to 20 minutes to ensure that all the moisture has boiled out of the A/C system. Note the vacuum readout on the A/C station. Allow the system to sit for 10 minutes. Recheck the A/C stations vacuum readout to ensure there is no loss in vacuum. A loss indicates a leak in the system, probably in one of the two replacement line connections. Repair as needed.

6

Remove the service hose from the high side service port and start the vehicle. Turn the climate control switch to "Maximum." Set the machine to charge the system with R134a and the correct amount of compressor oil through the low side service valve. When enough rigerant is in the system, the air-conditioning compressor will start and draw the rest of the desired amount of rigerant and oil into the system. Remove the low side hose, completing the replacement of the service port.

Properly working headlights on a car are vital for your safety and the safety of other drivers on the road. Fixing the headlights on your Mitsubishi Eclipse is an easily implemented task with the use of just a screwdriver and a few minutes of your time. The specific headlight required for your Eclipse will depend on the year it was made so consult a auto parts specialist if there is any questions on the unit required for your specific car.

Instructions

1

Purchase you replacement headlight. Check with the auto parts representative for the correct fixture for your year of Eclipse vehicle and the proper side that you are fixing. They should be able to give you the exact part for your needs.

2

Turn your car off and remove the keys from the ignition. Pop the hood of your Mitsubishi and make sure that it is properly secured so it does not close while you are repairing the light.

3

Look at the rear of the light fixture and locate the four screws around the light perimeter that holds it in place. Remove these screws with a flathead or Phillips screwdriver, whichever that specific year of car and light fixture call for.

4

Place one hand on the back of the light fixture and one on the front. Gently but firmly push the light towards the front of the car. Stop pushing when you have pushed it forward 2 to 3 inches.

5

Work your fingers behind the light fixture and disconnect the wires that are connecting the light to the car. There will be up to three sets of wires. Pull the wires away from the unit gently to disconnect them and set the old light aside.

6

Remove your new headlight from the packaging and slide it into the space where the old light unit was. Connect the wires in the back of the new light, push the light into place, and secure the light into place with the four new screws that came with the new unit or the old screws.

7

Turn the lights on to test your new headlight. If for some reason it does not work properly, unscrew the unit and make sure the wiring is properly connected. If not, take the new unit back and get a different one to try.
