  1. rear differential cover leak

    4x4 Drivetrain
    My '02 Envoy XL developed a slow oil leak on the rear differential. It was due for a lube change so I order a new gasket and change the oil. Cleaned the cover and replaced the gasket/seal, refilled w/ new Mobile1. The leak continues, it appears the cover has a pin hole where the GM part...
  2. Trailblazer fix 'putt putt' problem!

    General
    2006 Trailblazer. When I started it, it sounds like 'putt putt putt'. When I pressed on the accelerator the engine didn't rev up. All of the dash warning lights were on. I am looking for a clue as too what is wrong with it. Could it be something with the fuel pump, regulator or injectors? I...
  3. Water Leak! (In the rear cargo area, not the sunroof)

    Exterior
    I have a 2002 Olds Bravada that has been getting quite a bit of water pooling in the back when it rains. It's coming through where the two plastic panels meet on the driver's side. Any suggestions?
  4. Large/Fast Coolant Leak - after replacing thermostat and water pump

    OEM Issues
    I recently expietenced a cooling system failure on my way back to work on lunch break. My engine temp spiked and my engine alarms started going off. Luckily I was really close to my work. I was able to get it to the parking lot, opened up the hood and coolant was spraying/leaking everywhere. It...
  5. p0440 Issue...Resolution for Filler Neck Crack??

    OEM Issues
    I've been getting a P0440 code that won't go away. I have been chasing the usual suspects... I bought a new gas cap, I checked the evap vent valve in the back near the gas tank... it checked out fine (It activates and stops the flow of air/gas). I also checked the Purge Valve on the driver side...
  6. Photo of minor leak. A little help confirming?

    General
    05 4WD. It looks like oil, but seems like it should be Tranny fluid. I put my 13mm on the bolts, and with no effort they turned. So I snugged them up (Not sure how tight they should be)

  8. 2002 envoy apparent gas leak

    General
    Ok. So this is my problem with my Envoy. Every so often in the past 3-6 months I have had people say that they can smell gas when the ride in the vehicle, and one said it while walking past the vehicle. I have not had any Leaks on the ground as far as I can tell. I did notice the other day...
  9. Front Diff Empty... Cause?

    4x4 Drivetrain
    My girlfriend's Envoy has no fluid in the front differential. I discovered this during my first check of all the fluids and I didn't see any obvious signs of leakage, so who knows how long it has been like this. Obviously I will fill the damn thing back up asap. In the meantime, I have 2...
  10. Windshield leak, driver side near visor

    Interior
    Hi all. So I just discovered today that there appears to be a leak, from what I can guess is either from the door seal or the windshield on the drivers side. It appears as a wet spot in the fabric ceiling, just at the point where the fabric meets the plastic in the divider between the door and...
  11. No A/C

    General
    This seems to be a common thread, however I cannot seem to find the correct fit for our issue. We have no A/C and the shop says they need to replace two things: 1. Rear Evaporator Core 2. Rear Auxiliary A/C Lines 2b. (also in a footnote possible update kit of mounting block) Total est cost...

    OEM Issues
    About 2-3 months ago, I had a bit of a run-in with a guard rail and some black ice, and my '02 Bravada sprung an oil leak from a corroded metal line located on the driver side. The line runs down and connects to a rubber line that goes underneath the fan and radiator and then turns into another...

  14. AC Leak Check

    General
    I charged my Trailblazer once this year, and it’s not working again… I replaced the low pressure cutoff, as I have heard this valve is a weak link, and it is cheap and easy to replace. When I took off the cap to put the new valve on, it looked as though one of the Schrader valves was leaking...

    4x4 Drivetrain
    I apologize in advance for not being educated on autos, and the proper lingo. But here goes. Left front, leaking, mechanic used small camera to isolate leak and said it was the left side of the "gearbox" in which the "axle" went to. He took off a spring to remove the axle from the left side and...

    4x4 Drivetrain
    After a road trip, the next morning saw a small puddle, 3" maybe, under the car. Pulled it into the garage and climbed under it, and saw the attached picture. Hard to tell where the fluid is coming from, possibly the output shaft for the front wheel drive? Anybody else had problems similar to...

    I have an 02 TB LTZ 4WD and this morning I changed out coolant and replaced upper and lower radiator hoses @ 114K. Everything seemed to go according to plan until I added the last bit of coolant to the overflow reservoir (after having filled the radiator) and it just poured out the bottom of...
