The oil pump will not cause it to overheat. If all you have replaced was done correctly I would suspect a head gasket failure.

NJ 2002 chevy vet overheating changed water pump an the thermostat an flushed the radiator out, its not blowing any white or blue smoke out the rear oil is little dark and not milky at all


Change your fan clutch. Or if it's a electric fan have it checked. And make sure the outside of the radiator and a/c condenser is clean.

I have a 89 pontiac firebird Trans Am "GTA" 5.7L tuned port injected. My engine gets hot somehow and my car has a quick start but lower power afterward. What could the problem be?


Fix the radiator cooling problems. You will damage the engine if you keep running the car in an overheated condition.

1. Replace the thermostat in the cooling system
2. Replace the water pump
3. Flush the cooling system thoroughly and re-fill with the correct coolant. Bleed any air out of the system otherwise you will have problems with air blockages and thus poor coolant flow.

You probably do not know how to do any of this so take it to a reputable workshop or cooling specialist to have it done.

My 98 ford contour keeps overheating i just replaced the radiator and the water pump. And there is no water in the oil. The fans work but it still overheats . What else could be causing it to overheat?


I can't believe anyone would replace the waterpump without also replacing the thermostat. Once overheated, a thermostat is no good anymore. It must be replaced.

But that is not the only possibility. You could have a bad head gasket, without having oil in the water. Only a pressure check can tell. You could also have a collapsing lower hose, as water pump suction causes it to pinch off. You could also have an air bubble from not bleeding it properly when refilling. You could also have a loose waterpump belt. You could have put in the wrong waterpump, as the type for normal V-belts runs the opposite direction of the type for serpentine belts.
There are many more, but that is all I could immediately think of.

Overheating... changed waterpump and thermostat. when i use a/c it cools off?? on an 88 chevy 4x4 350ci. Any suggestions would be helpful..


It sounds like your radiator is quite stopped up with corrosion and or other foreign material. Try flushing it yourself first and if the problem persist take the radiator to a shop and have it boiled out.

Overheating, removed thermostat still gets hot. waterpump? no evidence of water in oil..


Your problem could be the water pump or a clogged radiator. Get the radiator flow checked at a radiator shop to find the answer.

1999 chevy malibu engine keeps over heating, possibly a blown head gasket?


Overheating could be a combo of many thing's.If your thermostat is stuck you will have no circulation which will cause overheating.Also if your eng. has alot of miles your water pump may be in need of replacement.Listen for your radiator fan motor and be sure that's working and also check to see if you radiator is good.If your loosing antifreeze because of a headgasket you will see a white cloud out of the exhuast because it is burning it and sometimes you also get a little in your eng.oil.Using a pressure tester on your coolant system will help to diognos the problem,if you have a leak some where it will not hold pressure.Sign,s of a bad waterpump are poor circulation and a antifreeze leak from a vent on the waterpump.Be sure the eng. is cool before working on it.Hope this was helpfull.

Overheating


there are three hoses leading to the water pump. the biggest one oviously goes to the thermostat housing, but the other two are much smaller 1 inch hoses, one of wich goes on the water pump and the other on the thermostat housing. if you follow the hoses one will connect to the upper part of the overflow for the radiator after hitting a T in the lines, that hose connects to the thermostat housing, and the other goes to the water pump its self.
