Question Answered: adding transmission fluid to a 98 chev cheyenne 5.7 litre
November 04, 2010, 04:20 PM
I am assuming your 1998 Chevrolet 1500 Pickup has an automatic transmission. There should be a dipstick located near the fire wall on the passenger side. Check the fluid level with with the transmission fluid warm and add fluid via the dipstick tube as necessary.
Question Answered: i seem to have a leak were there looks like a plug or hole like a distributer .
November 04, 2010, 04:14 PM
You are correct, That hole is where the distributor used to be in that engine block. The ignition system in your 1995 Buick Century does not use a distributor. What is in the hole however is not a plug, it is a gear driven shaft that drives the oil pump just as the distributor shaft used to do. There is an o-ring at the top - just like a distributor o-ring. The o-ring is probably hard as a rock and not sealing any more. The oil pump drive will need to be removed and the o-ring replaced. Even with everything out of the way it can be a bit difficult to remove the oil pump drive.

Question Answered: Service engine soon
November 04, 2010, 11:07 AM
Once the fault has been corrected which caused your service engine soon light to come on in the first place you can do one of two things. Reset the light using a code reader or scan tool. Technicians will normally do this after completing a repair, your local auto parts store may also perform this service. The second way is to wait for the on board powertrain control module complete its system checks and turn the light off itself. This could take days or weeks depending on what the driving conditions were when the fault code as first set.
Question Answered: AC tensioner pulley rattles
November 04, 2010, 11:00 AM
I have seen this problem on some 2002-2003 GMC Yukons, so this may or may not apply to your vehicle. What I have seen is the load of the compressor causing the belt and tensioner to jump, hitting the transmission cooler lines causing a rattling noise. There is a service bulletin from GM for this issue #03-01-38-019A. But again, it does not specifically apply to the 2001 model year. The repair is to replace the compressor with an updated unit and install an inline filter. If you can verify you have the exact symptoms as I have described you may still have an issue with your compressor. Perhaps discussing this issue with your local GM parts supplier would be a good idea. They may be of help in determining it the 2001 and 2002 compressors are the same, if so perhaps you could try the updated compressor in your Yukon.
Question Answered: climate control

If the A/C system is low on refrigerant the system will automatically switch over to econ. I would recommend you have the A/C system in your 1996 Cadillac DeVille inspected for proper refrigerant charge. If it is low on charge perhaps leak diagnoses should be performed.

The cooling system in your 2002 Jeep Liberty should be check for a leak. Special tools are available to pressurize the cooling system.

If no leaks are noted and the coolant loss continues it could be possible that coolant is leaking into one or more of the cylinders.

Problem Reported: Speedometer Not Working and/or Code P0722 Stored in PCM
February 18, 2016, 02:18 PM

The speedometer may stop functioning with code P0722 stored in the powertrain control module (PCM). This may be caused by a worn speedometer gear due to coolant contamination of the transmission fluid. If contamination is found the radiator is most likely at fault. The transmission should also be thoroughly inspected and repaired or replaced as required.

Problem Reported: Fuel Gauge Needle Stuck on Wrong Side of "Empty Stop"
February 23, 2012, 10:17 AM

Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.

Comment: Floor Mats and Unintended Acceleration
July 10, 2012, 12:02 PM
A well placed strip of heavy duty, self adhesive Velcro on the back of the floor mat may help keep it in position. First check to see if the "loop" side of the Velcro will grab the carpet. If it will, placing a strip on the bottom of the floor mat at the edge near the drivers seat should help.

Comment: True or False: Let Your Car Warm Up Before Driving
April 14, 2011, 08:36 AM
Cpete, When idling or driving a vehicle when cold, condensation will form in the exhaust system. More exhaust flow through the exhaust system while driving a cold vehicle will actually warm the exhaust system faster that if you were to let the engine idle until the exhaust system warmed up.
