It could be as simple as the radiator cap or as serious as a leaky head gasket or intake manifold gasket (GM V-6). Other possibilities: bad temperature sensor or electric fan, bugs and dirt on outside of radiator, plugged radiator, wrong coolant mix (use 50/50 water/anifreeze), plugged catalytic converter (would also affect performance). If you suspect thermostat, replace it, do not just remove it. You've already mentioned water pump and radiator.
You can warp the head and crack the block if you keep it running for too long while its overheating, that's only two things. Fix the problem before you blow the engine.
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
with my 95 mx3 i was having the same problem all i did was adjusted the angle of the radiator and the over heating problem stopped id try that
replace it
By finding the cause of the overheating. It is normally, bad thermostat, bad water pump, clogged radiator, either internally or externally, a defective cooling fan, or defective cooling fan relay.
I had a ford contour that overheated a lot. Took it to several mechanics and no one could find a reason to why it was overheating. Since I couldn't fix the problem, I just kicked on the AC when it started to run too warm and that kept it at normal running temp.
what is the cost to fix an overheating Subaru Legacy Wagon. Is it the thermostat? How much are they to replace?
The further north you drive, the cooler the engine will get. If the problem doesn't resolve itself by the time you pass the Arctic Circle, you should call On-Star or AAA for further assistance.
I suggest you take your car to the dealer and they might be able to fix the problem.

Possibly the thermostat is broken. Easy fix but if not that then it may be the water pump which is a bigger problem only because labor is difficult.
we are still trying to fix the problem
