Need help on 97 4runner overheating!!! - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 97 4runner, lately my car has been overheating. Radiator is good, no cracks, no leakages. New radiator cap. Upper and lower radiator hoses are good, no cracks, no leakages. There is actually no leakage of radiator fluids anywhere, no sign of it. The only thing i can think of is the theromostat. Does anyone know where it's located and is it a easy fix? Please anyone with any suggestions?

Have you checked the coolant level? How does it look? Nice and green or Toyota red depending on what coolant you are using? When does it overheat? Slow city stop and go, at idle, after a long drive? Have any work done to it recently and then the overheating start? No leaking of fluids, so has it boiled over or is it just the temp gauge saying it's hot? 4cyl or 6cyl?

tean_lunatics,

Hear is a link for you to check.

It shows the location of the thermastat. If you purchase a new t-stat, you should test it in water on the stove to make sure that it will open, I have seen new ones fail to open so I would check it first to make sure.
