Overheating

[Ivan141]

Well I once had all the coolant blown out through a finger sized hole on the freeway...one minute everything is fine, the next the check engine light was blinking and my engine started stuttering. So I would agree that a 4age does overheat fast.

I would suggest doing a little checkup of all the cooling system. Check the radiator for leaks, check the waterpump by removing the timing belt and turing it round. The bearing should not give a lot of lumpy resistance, but turn smoothy and evenly. Then just change the thermostat for a new one...it might not open up far enough anymore causing the coolant to circulate slower. Checking hoseclamps is also easy enough to do..

BTW, why did you run the car at 170km/h for 15 minutes?? I would only consider that in germany, and even then I would probably go crazy due to the high rpm's the engine runs at those speeds.
