1992 Toyota Camry
Question: My car keeps running hot
On/ around Feb. 28, 2009 I had to have my car towed in, the mechanic said I needed to have the water pump replaced and the thermostat replace. I did that, and went and picked up the car, when he called and said it was finished. I drove it around that day and it runs hot with me....I took it back and he calls and says he replaced the thermostat again....it still running hot. Please help me I love this car and I can't afford another one right now.

The Toyota Camry doesn't have an inherent problem with running hot. I would have a "block check test done" this will check to see if the head gasket is blown or mildly leaking..The cooling system is tested for the presence of Carbon Monoxide. Carbon Monoxide is a by product of combustion and the only way carbon monoxide can be present in the cooling system is if the cylinder head gasket is failing or the cylinder head is cracked. There are several types of test testers, they draw gasses from the cooling system through a chemical, if the chemical stays blue in color, there is no head gasket problem ,if it turns green or yellow there is carbon monoxide present and the head gasket is failing. Snap on and Matco sell them from the tool truck they are relatively inexpensive. I have seen them online for $60 but don't have the part number here with me right now.
Run the engine and ensure the electric fan works!

Great reply "Been there", often over looked/ Pressure cap has two valves on it one to burp "hot coolant" into the expansion tank and the other to retrieve that coolant from the expansion tank as the engine cools down.

I had the same problem in my 1992 camry and did everything you did, got all the advice you are getting. The coolant would over flow from the coolant resevoir after driving for a short distance and the car would run hot. I then was told to replace the pressure cap on the radiator-the one in the back. Total cost $12.00 including tax.
