Easiest to hardest....1. Check coolant level, 2. Replace thermostat, 3. Flush system, 4. Replace water pump (do you have over 100,000 miles?), 5. Replace radiator. Also, Is it actually getting hot or is the temp sending unit bad?

hopfully the oil leak isnt causing overheating issue. if thats the case, your out of oil. if oil level ok, check coolant level, and if low, track down the leak source. make sure belt is intact, and water pump is spinning, etc. let me know what you find and i can help further.

02 sunfire overheating


make sure you have radiator full of coolant
run the car to operating temperature
check the operation of the cooling fan
feel the upper radiator hose and the lower radiator hose. they both should be hot.
if one is cold then you may have a bad thermostat or restricted flow
if cooling fan does not come on when engine is hot then you have bad cooling fan switch, relay or motor.
good luck

What can cause overheating in a 2000 pontiac sunfire


Replace the thermostat. It will be fine after that. I know thats what everyone says anytime there is an overheating problem but in this case with the way the system works and it has been working fine up to this point, it's gonna be the thermostat.
