    Hey fellas. Got an 04 4.2 with 143,500. Recently just flushed my system out of the old dex cool with some distilled water then filled it fully back up with some 50/50 mix and i now have my upper radiator hose dribbling just a little fluid. Thats obvious, but incase it isnt so transparent and i...

    One of my kids pressed the open button a couple winters ago while it was frozen shut. Of course something broke. At least it doesn't leak. It seems like a monumental job if I decided to replace it. I'm sure the inside trim and headliner would have to be removed. Probably not worth it but I'm...

    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...

    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...

    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?

    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...

    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...

    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)
  9. The "How-To" and DIY Section
    I am a new member here and I am kind of clueless when it comes to cars. I have a problem with power steering fluid leaking from appears to be called the tie rods or the lines. I am not sure which. I can take a picture and post it here if need be. I just know where the source of the leak is...

    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...

    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...

    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...

    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...

    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...

    Hello. I'm the proud owner of a 2004 Chevy Trailblazer LS Ext. I have owned this vehicle for almost four years and never had a problem until now, but first of all, I want to thank everybody. I'm not a mechanic. I'm a network/ systems engineer. I work with servers, switches, routers...

    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...

    Greetings, I've been battling a power steering leak for about a month now. Leak was always making a puddle under the driver side tire. Finally had time to degrease and wash out the area to inspect wear this leak is coming from. It is coming from a boot cover that is connected very close to...
