The place to start is the thermastat. Sounds like it is probably stuck closed.

    Maybe the gauge is faulty and the car is not really overheating. It seems to be showing hot very quickly. The radiator cap can also cause overheating if it isn't sealing correctly.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

My radiator on my 1994 toyota hilux sulf is over heating just sarted in last few days. Temperature gauge fluctuates when i turn air conditioning on.how do i fix this


First check if you have any leaks in the cooling system , then check if level is correct(radiator and expansion tank , check level when car is cold , never open radiator when it's hot).
Then verify operation of radiator fan , if it's electrical fan it should comes on when temp. goes over normal,
if it's a clutch fan- it should pick up a speed and be more loud. If fan is not on and engine is starting overheating , check upper and lower radiator hoses.
If upper hose hot and lower hose cold or warm then you might have stuck close or prtially closed thermostat , difference between lower and upper hoses when t/stat works ok is about 10-15 degrees,
not really noticeable for hand.So if you don't feel a lot of difference between hoses temp. , and fan is not on , check fan or fan clutch itself.
If lower hose cold , replace thermostat and purge system.
If everything above is working properly , and it's still overheating , you may have bad water pump or head gasket.

99 couger 2.5L 6 Cyl-temp gauge maxing out, overheating


I will normally remove rad cap when cool. Start engine, set heater in car to heat & turn on blower, if you use defrost setting, the rad fan &/or AC fan will come on, and you don't want that. Then while running with cap off, make sure coolant in rad is an inch or 2 from top of rad, and let it run. When engine gets to normal operating temperature on the gauge, you'll start to see more flow in radiator, and rad fan should come on shortly after, to cool the incoming hot liquid in the rad, that tells you the thermostat opened as it should, and the process starts again, engine coolant gets to temp, thermostat opens, hot goes to top of rad for cooling, and cooler liquid goes out the bottom to engine, etc etc. If your heater is not on while doing this, the coolant doesn't get to heater core in most cases, thus creates an airlock, or will cause level in rad to go down when it is turned on, and thus reduces amount of coolant in rad, plus airlocks in the entire system. So, let it run to the point that the rad fan comes on & off on it's own, about 3 times, while you watch the gauge, to make sure it doesn't overheat, if it does, shut it off and let it cool down & try again. if all appears good, top rad up if needed to an inch or so from top, put your cap on properly, add coolant to proper level in return bottle & try it and see what happens. Remember though, I am assuming thermostat was put in correctly, rad in good shape, fan is working properly as well as water pump doing it's job. If this method doesn't work, get back to me with results.

Faulty temp switch. replace and try. This component is prone to failure and is not expensive to replace.

Temp gauge goes to full hot while at Idle


Check the auxiliary cooling fan for operation. As the engine temp rises, it should kick on to bring the temp down. U may have a bad motor on the fan, or more likely a bad fan switch.
