Drain the coolant until the level is below the thermostat (use the radiator petcock for that). 3. Remove the crossover exhaust pipe. 4. Remove the radiator hose from the housing. 5. Remove the thermostat housing and gasket. 6. Remove the thermostat. 7. Clean the mating surfaces of the block and the thermostat housing. Install 1. Install the thermostat into the engine block. 2. Install the thermostat housing and gasket. I would replace this gasket. They are pretty cheap and best not to re-use the old one and have a leak. 3. Install the thermostat housing bolts. Tighten bolts to 25 Nm (18 lb ft). This is critical as the housing is just made out of aluminum and you would not want to warp it and create a leak. 4. Install the radiator house to the thermostat housing. 5. Install the exhaust crossover pipe. The studs and nuts are tighten to 25 Nm (18 lb ft). The heat shield bolts are tighten to 10 Nm (89 lb in). 6. Install the air cleaner assembly and duct. Now would be a great time to replace the air filter if you need to. 7. Fill the cooling system, per procedure in the Owner's Manual. After you have filled it, use the air bleeding procedure to remove the excess air from the system. You may have to readjust the level by adding coolant and re-bleed the system after a couple days of driving to burp the air out of the system.' good luck

| First, my temperature gauge quit working, so my service engine light came on and it makes the cooling fan (which has never come on before) come on after i turn off the engine and it makes a gurgling sound. Second, while traveling at 60 mph my car runs at 3000 rpms it doesn't shift out. Third, about every 3000 miles the low engine oil level comes on and I'm about 1 1/2 or 2 quarts low. Its not leaking on the ground and it doesn't smoke so I don't know where its going. If anyone has any answers or suggestions please help. | |

Replying to: ray80 (Feb 16, 2007 5:40 am) We bought our Aztek new in 2003 and started having problems that same year...so many problems in fact that we filed lemon law on it, and GM agreed it was a lemon  . Only problem was GM wanted me to pay a usage fee to "buy it back"...that was like $2800.00 which I didn't have  ...so we kept the vehicle, bad move!!! The car spent over 68 days in the shop the first year! Nothing but problems since then...brakes (3 times in one year), hubs (3), rotors (3 times), tires (2 sets), coolant leak, battery, rear hatch, Check engine light, SES, ABS, paint peeling (in 2003, no less), gas gage, bearings, gets stuck in park (daily), radio light is failing, tranny problems, electrical...and the list goes on and on!  So many of the same things that are noted by tons of customers on this site alone...how can they (GM) get away with this???  Seems like we could all get together and file a class action suit or something!
