Hey I got a 2005 Comp G GTP with 70,500 miles on it, just recently the car started to get just under overheating on the gauge and the heater wont blow hot. Thought it may be a thermostat so changed that and it didn't help the temp gauge then just started moving and would still get just under overheating with no hot heat. So I took the car to my mechanic and he found that the water pump was bad so changed that. Still did not fix the issue. So then took the engine apart assuming maybe a bad head gasket or bad head. Had the heads sent into a auto shot and the heads are in perfect condition and didn't even need cleaned up. Really puzzled with what this problem could be were putting the engine back together tomorrow with new head gaskets.
If anyone has any ideas please let me know!! Thanks
