View Full Version : 02 Forester Overheating Issue
03-13-2012, 01:34 PM
I have an 02 Subaru Forester that's having daily overheating problems. I attempted to replace the motor last summer and all cooling components were replaced as well. The new motor was knocking so I sent it back. The old motor never over heated after being re-installed with new cooling components. Now, new re-manufactured motor has been installed and it's overheating in the same way. It will hit normal operating temperature, then rise with higher rpms and climbing hills. It also rises at idle. Any ideas? I know, head gasket issues were a major problem. The car has a newly re-manufactured motor in it now. Is it possible that the thermostat is acting up after the motor re-install?

Sound like a radiator is clogging or something restrict in a cooling system if coolant wasn't leak (burning out).
How about do the cooling fan operate when engine got hat? or may be air is still trapping in a system? Bigisland

There is a lot of noise on the blogs about folks who may have used "stop-leak" type products in their Subaru and the effect is a restricted flow throughout the system. If you did this or if you do not know if it has been used, take the car to a Suby friendly shop and have the system flushed with Subaru flush only. Apparently these cars are very finicky about additives in the cooling system and only Subaru "conditioner" should be used.

..So, did you say that all cooling components have been replaced?
Radiator, hoses, heater core, radiator cap, thermostat?
Do the fans come on ? Are you ABSOLUTELY sure you have all the air out of the system? Do you have any coolant in the overflow?
