98 Camry Overheating

Do both fans work, are hoses new, Is it a toyota thermostat, is air removed from system, is antifreeze 50-50 mix. how old is water pump. Does water increase and decrease when cool in expansion tank, Is radiator cap old. if the gauge says you are overheating you probably are.

Both fans do work. Hoses are not new. The thermostat is not from Toyota it is what Napa autoparts gave me for the model car I have. I don't know what you mean by is air removed from system. I am using a

50-50 mix. The water pump is old. Radiator cap is new.

Use Autozone's Loan-a-Tool program, check out the cooling system pressure tester:

I hope it's not a blown head gasket, it could give that symptom. Did you install the thermostat with the jiggle valve on the top side? Stant has more decent OEM style thermostats now, I might use it in the future but so far this is one maintenance item I still insist on dealer counter. Use 50%-50% distilled water and preferred Toyota Red.

Also, does the top hose get hot when the engine is?

I myself bought a aftermarket thermostat that never worked or sealed it was made smaller. Air is in the system unitl you bleed it or it works its way out. Temp moving up and down to me indicates a bad thermostat. Was the cooling system flushed. If you had a head leak you would loose coolant and often the oil goes milky in color. Bottom hoses can collaps if bad when hot.
