Question about 1994 Pontiac Grand Am
Replaced the rad. core, water pump, head gaskets, TCS, heater core and thermostat in 7/08 and the car was running great until a couple of days ago when i lost heat in the vehicle and then it started to overheat. no visible leaks but when i make sharp turns i can hear boiling liquid. I pulled the thermostat to avoid overheating but to no avail....where am i going wrong?
What engine do you have? One noted problem with the 4 cylinder engines is the reliability that at some point the intake will crack. I went through all the same things when I bought my 93. Drove off the lot, started overheating, replaced the thermostat and still had the problem without moving from the driveway. Look all around the intake. Make sure car is full of coolant and have the engine running. Most likely you will see a small coolant leak on the backside by the firewall. These cars were known for this problem. By the way if this is the problem make sure you take it to a reputable mechanic, make sure you get a new one installed. I had a used one and had the car back in the shop the next day. It then sat there for 2 more weeks while the used car dealer and I had a "discussion".
