Make sure the electric fan if equipped is coming on after 10 - 15 min. of operation if not replace the fan relay. Make sure antifreeze/water is a 50/50 mixture, If the fan relay doesn't do it replace the fan if the car has no electric fan the clutch fan may be faulty if equipped.

There are other things to be checked, such as the radiator fan and the water pump. You would need to find out if the fan is coming on at 220 degrees and if the pump is pulling coolant thru the radiator.

Do you hear the cooling fans coming on ,if you do then you might have a blocked radiator or cylinder head / head gasket problem. If you dont ever hear the fans come on you have an electrical problem ,maybe a fan switch or motor or wiring/fuse issue.

I have a 2002 chevy impala my car overheats when in stop


Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

Overheating - Not holding water


Check your engine oil. If there is fluid in it (radiator fluid)....bad.

Do you have smoke...white (not billowing, but like it disappears)....from the exhaust?....bad....

Head gasket is bad.
