    02 GMC Sierra A/C Not Cooling

    Just bought a 2002 GMC Sierra 6.0L yesterday. I noticed the A/C didnt cool. Got home and noticed the belt was missing for the A/C compressor. The pulleys were really rusty so the belt must have been missing for a while. All the pulleys spun fine by hand. Turning the compressor by hand, it felt...

    Malibu Torque Converter Hunting Uphill in 3rd

    I posted a while ago asking about difference in MAF Sensor Brands. I finally got my Delphi MAF and it really tightened up WOT shifts. But a very common problem with these cars is an uphill surge due to the torque converter locking and unlocking. GM issued a TSB on this way back in 2003. Here it...

    Difference in MAF Sensor Brands

    My check engine light come on the other day for the mass air flow sensor. No driveability issues. I went to Autozone and they had a new Duralast one for 90 bucks. I slapped it on in the parking lot and tried to leave. The engine would start and shut right off. I took it back in and got another...

    Things To Check Before A Road Trip?

    I am taking my 99 Malibu on a 13 hour trip one way at the beginning of May. I am slightly concerned because it has 245,000 miles and Im scared something will fail. It runs fine around on shorter trips (6 hours or less). The car has been maintained religiously since it was new, and is still in a...

    Nasty oil leak at oil pan and timing cover

    Hi. I hope all of you had a great Christmas. I noticed a spot of oil today where I parked. I got home and found out it is leaking badly between where the oil pan meets the timing chain cover.

    Transmission Acts Funny when Warmed Up

    Hey guys. Ive been trying to figure out if my transmission problem(4T40E) is worn clutch or solenoid related. It runs great when its cold. The shifts are fast and tight. But after driving for about 15 miles, the shifts from 1-2 become way too soft, and at WOT, 1-2 shift bangs really hard 3...

    Whats the correct r-134a charge for my car?

    Hey guys. I hooked my 1999 Malibu V6 up to the recovery machine becuase the A/C wasnt doing the best. It had 1.54 lbs in it. Now the sticker under the hood says charge with 1.35lbs of R-134a. But EVERY website says to charge it to 28oz which is 1.75lbs... Right? It only gets the temp down to...

    Transmission Fluid Level Question

    I changed my fluid about 3 months ago with 7.4 quarts (99 Malibu 4t40e). I changed the passenger side axle and lost a lot of fluid. I forgot about losing that fluid and kept driving it. I disconnected the cooler line for some reason and lost a lot of fluid also. I bought a quart of fluid and...

    I've got another mystery for you guys lol. This time it's not on my Malibu, it's on my grandmothers 1995 Buick Lesabre. She was in town one day and the car started knocking really bad. The compressor was locking/locked up. She took it to a garage. They put a new compressor, and claimed to put a...

    Engine/Transmission Noise After Spinning In Snow

    We got 6 inches of snow here, and like an idiot I took my 99 Malibu down my driveway and out on the icy road to go get some milk(haha) and coming back up my driveway I got stuck. I spun and turned the wheel back and forth, the right wheel spin, then both of them started spinning and I starting...

    Engine Knock. Is It Rod Bearing or Lifter?

It has 221,000 miles on original engine and transmission. The engine has a knocking sound coming from the bottom (oil pan area)...
