Being the last Pontiac production car, Vibe offers a sporty design and the car is functional, spacious and efficient. If you are lucky enough to get one, it may have needed an alignment. The following specs are cited by the manufacturer for alignment.

Camber

Camber is the measurement in degrees from the true vertical. The Vibe camber angle should be the same on both left and right sides. The angle must be -0.57 with the measuring accuracy of 0.75 degrees on the front wheels and -1.45 with the measuring accuracy of 0.50 on the rear wheels.

Caster

Caster measurement is essentially the reading of camber while turning. Caster angles must be 2.78 degrees with the measuring accuracy of 0.75 degrees.

Total Toe

Total toe angles on the front wheels must be zero degrees with measuring range of 0.20 degrees and 0.26 degrees with the measuring range of 0.26 degrees on the rear wheels.

The stylish Porsche cars come equipped with a remote entry system for controlling the door locks and alarm system. The system is controlled by a wireless transmitter in the Porsche key fob. This device has three buttons: lock, unlock and a panic alarm button. Before you can use the key fob with your car you must program it to work. Most keyless transmitters come already programmed from the Porsche dealership, but you can also reprogram it yourself using the ignition key and the security code.

Instructions

1

Enter the Porsche by the drivers seat and be sure everything is closed. This includes all doors, boot lids and bonnet.

2

Insert the key into the ignition and turn it clockwise until you start the Porsche engine.

3

Turn the 911 engine off and remove the key from ignition. Wait 90 seconds before continuing to the next step.

4

Turn the ignition to the "On" position and wait 15 seconds. This position is as far as you can turn the key without starting the engine. The immobilization light located in the 911 dashboard clock will go out.

5

Turn the ignition off again then turn it back on. After 15 seconds, the immobilization light will begin to blink.

6

Enter the four digit security code using the ignition. For instance, if the first digit in the code is three you would turn the ignition from on to off, then back on. This would equal 1 digit, so you would repeat this step two more times if the first digit is "3." Afterwards, wait for the immobilization light to flash then repeat this step for the next digit. After the fourth and last digit is entered, the light will flash again to signal you are in programming mode.

7

Press a button on the key fob and hold it until the LED light blinks. This will indicate it has been programmed.

A 2002 GMC truck needs an OBD scan tool to clear the "Service Engine Soon" light. There is a computer within the vehicle called On-Board Diagnostics, or OBD, that monitors the various systems within the vehicle. It also keeps track of when you need routine maintenance. To keep the computer functioning properly so it keeps track of when the maintenance is due, you must use the OBD scan tool to read the code to find out exactly what type of servicing is needed. Then you simply use the tool to reset the light. Make sure you have the servicing performed before you clear the light.

Instructions

1

Locate the diagnostic connector port on the drivers side of the vehicle. It is located on the underside of the dashboard, between the center console and the steering column. Plug the OBD scan tool connector end into the diagnostic connector port.

2

Put the key into the ignition and turn it to the "on" position. This will power the scan tool on. Make sure you dont turn the key too far and start the engine.

3

Wait for the code to appear on the screen of the scan tool then press "Erase." If you are prompted by the question "Are you sure?," press "Yes." This clears the codes and you should see the "Service Engine Soon" light disappear from the instrument cluster. Unplug the scan tool and turn off the vehicle.

4

Turn the engine on and check to see that the "Service Engine Soon" light is still off.

When youre driving down the road on a hot day, nowhere near a gas station, and your autos air-conditioning starts malfunctioning, all you can think of is why you didnt get those repair tools and put them in the trunk. If youre one of the lucky ones and you have some tools in your car, you may be wondering whether theyre the right ones. There are some basic repair tools you should know about and have available for emergency maintenance. However, it is best to leave the AC repairs to a professional because refrigerant is a hazardous substance.

Safety and Service Manual Tools

The most important tools are for your safety. You should wear safety glasses, gloves, a face shield and apron the entire time you are repairing your autos air-conditioning system. Your cars AC unit can be extremely hot and the possibility of contact with refrigerant during recharging requires caution. You also need your cars service manual to pinpoint the exact pressures and directions for the AC repair, which can vary depending on the car model.

Diagnostic and Detection Tools

You need leak-detection diagnostic tools to determine the cause of your autos AC problem. There are dyes you can insert into the system and then check the pipes for remnants of the dye to confirm a leak. You can also purchase electronic leak detectors that alert you to refrigerant leaking into the atmosphere, or LED detection flashlight tools. If your auto has an AC leak, you should take it to a repair shop for the root cause to be remedied; any superficial corrections will be short lived.

Recharging Tools

To recharge your cars AC system you will need pressure gauges, a charge hose and refrigerant. The more inexpensive way to recharge the system is with only a low-pressure gauge; however, Autos.com recommends using both a high and low pressure gauge for best results. The charge hose connects to both the gauge and refrigerant and pierces the refrigerant can so it can enter the AC system. Most cars use a R-134a refrigerant that can be bought at your local gas station or auto supply store. There are also gauge and refrigerant sets sold that contain most of the repair tools you would need for your autos AC.

When the car horn dies on your Toyota, the only way to fix it is to replace it with another horn. Its important to make this repair as soon as possible. While you will still be able to drive the vehicle, it will not pass a state inspection. The horn is important in ensuring your safety as you drive. It alerts pedestrians and other drivers to your presence. Replacement horns can be purchased at auto parts dealers or junkyards.

Instructions

1

Open and stabilize the hood of the car, making sure to prop it up so you can operate under the hood.

2

Find the horn attached to the inside of the cars grille, in front of your engine.

3

Unscrew the screws that hold the horn in place at the front of the grille. Unplug the electrical harness.

4

Remove the horn from your Toyota.

5

Insert the new horn at the same spot from which the previous one was removed. Screw it in place with the screws you removed earlier, and plug the power wires into the new horns socket.

An internal combustion engine needs four essential things to run. They are: air, fuel, compression and spark. Those four things must work together in perfect harmony or timing. When timing a small block Chevy, we really just change the specific time at which the spark plug will create a spark and cause an explosion in reference to the position of the piston when it is near top dead center in the cylinder.

Instructions

1

Grind the electrode off the bottom of an old spark plug, dont damage the threads. Place the spark plug in a vise and hammer a punch through the spark plug to remove the porcelain. Cut the head off a 3/8 inch by 2-inch bolt with a hack saw. Grind the bolts shaft round and smooth where the head was removed. Insert the bolt into the spark plug so the rounded shaft protrudes out of the threaded end of the now hollow spark plug about 1 1/2 inches. Weld the bolt to the spark plug on the opposite side of the threads. Allow this plug stop to cool.

2

Remove the negative battery terminal from the battery of the vehicle. Remove all the spark plugs from the small block Chevy engine. Label the spark plug wires to keep them in order for easy replacement.

3

Clean the harmonic balancer so the zero degree line can be seen. Use a wire brush if needed. Insert the special modified spark plug into the number one cylinder of the engine. The number one cylinder is the cylinder closest to the radiator on the drivers side of the vehicle.

4

Rotate the engine very slowly and gently by hand until the piston comes up softly against the plug stop. Make a prick punch mark that aligns perfectly with the zero mark on the timing tab. Rotate the engine in the opposite direction very slowly and gently by hand until the piston comes up softly against the plug stop. Again make a prick punch mark that aligns perfectly with the zero mark on the timing tab. Immediately remove the plug stop.

5

Measure the exact distance between the two prick punch marks and divide that measurement by two. The true top dead center is exactly half the distance between the two punch marks and there should be a line labeled with zero degrees on the balancer, if the balancer is not damaged. If the original zero line does not fall exactly halfway between the punch marks, scribe a new line using a hacksaw blade. Use this new and precise line to time the engine.

6

Reinstall all the spark plugs and reattach all the spark plug wires. Reattach the negative battery terminal to the battery. Slightly loosen the distributor hold-down bolt located at the base of the distributor shaft. Remove the vacuum line from the distributors vacuum advance and plug the line with a small bolt.

7

Set the knob on the timing light to the desired timing degrees according to the specifications for the vehicle. Also, adjust the engines idle speed to the desired specifications for the vehicle, using the digital readout on the timing light. Clamp the timing lights pickup clamp to the number one spark plug wire. Clamp the red power clamp to the positive terminal of the battery and the black ground clamp to the negative terminal.

8

Start the vehicle. Aim the timing light at the harmonic balancer. With the engine running, align the top dead center mark on the balancer with the corresponding mark on the timing tab. Rotate the distributor in one direction or the other to align the marks as needed. Tighten the distributor hold-down bolt when the marks align perfectly. Recheck the timing to be sure it did not move while tightening the distributor. If it moved, repeat the timing procedure until the marks align and the distributor is tight.

9

Reset the idle speed and remove the timing light. Reconnect the vacuum line to the distributor the timing should be set.

A vehicles engine has many intricate components that work as a team to bring power to the drivetrain, resulting in movement. The camshaft is an important piece of the engines motion puzzle.

Identification

A camshaft functions by managing the engines valves. It does so by allowing a set amount of fuel and air into the compartment for combustion to move a vehicle along.

Considerations

Damage can occur to a camshaft in a variety of ways. In particular, the camshaft works in conjunction with the timing belt. If the timing belt snaps, the valves controlled by the camshaft can become warped or bent because the camshaft will have halted all movement.

Other Considerations

Oil plays a large part in possible camshaft damage. If the oil becomes low or develops an incorrect viscosity, the camshaft can wear down from poor lubrication. If you do not resolve the situation, this wear can turn into a complete breakage, causing costly repairs.
