Probably the water pump. these impellers go bad and if the regular service schedule is not followed correctly the pump will go out. These things are designed to fail at a set interval.
your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.
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.
Low coolant? System air bound? Hoses collapsing under pressure? Water pump not circulating coolant?
Low coolant level? System airbound? Cooling fan not working? Radiator plugged or restricted? Water pump not circulating coolant? Defective radiator cap?
possiable head gasket
my 1993 Toyota Camry radiator had a hole in it it was overheating. I replaced the radiator. The car is still overheating where is the thermostat located. First, drain your coolant from the radiator. Find your lower radiator hose and follow it to the metal housing. This is the thermostat housing. Remove the 2 nuts with a 10mm wrench. Remove the thermostat and replace with new one and new gasket. Re-install and re-fill your radiator with new coolant. Drive the car with heater running. Allow the engine to cool and top off the radiator. Add coolant to the reservoir to halfway between Full and Low.
Probably the thermostat is sticking.
Thermostat, water pump, radiator cap, headgasket, low coolant.
The most common cause of overheating is a thermostat stuck in the closed position. Other causes of overheating could be a clogged radiator, faulty water pump, a faulty radiator fan relay, a faulty radiator fan motor, no coolant or low coolant level.
Low on coolant, radiator fan inoperative, thermostat failed, water pump failed, radiator plugged
Low coolant, failed water pump, restricted radiator, inoperative radiator fan, thermostat,
Could be from a variety of things. Commonly overheating occurs when the car is low on coolant, broke thermostat or the radiator needs repairs.
