I will need more info. On this But, The Waterpump, Thermostat, Low Coolant, Bad Belt Tensioner, Clogged Radiator, Fan Clutch Or Cooling Electric Fans can ALL Cause this Problem. Please Rate My Response! Thanks!

Still running hot, can a intake vacuum hose make this car run hot, and does the bleeder screw need to be all the way open to bleed out all air


Vacuum leaks can (in some cases) make an engine run lean, and that will indeed make it run hot and potentially even burn valves. Modern computer controlled systems usually adjust fuel mix for minor leaks, and set codes for major vacuum leaks that can't be compensated for. Bleeder screw does not IMHO need to be open all the way, however I have seen some cars where the valve is not located at the high spot of the cooling system such that air can be trapped somewhere.

My chevy impala keeps running hot eventhough the radiator and the fluid isn't getting hot. But after running for a short period of time or trying to drive for a short period the car runs hot and c


I would start by checking the fluid to make sure it's at the proper level, Then check to see if the thermostat is opening like it should. If you have good flow and you get heat inside the car but the car still overheats I think I'd be checking for blown head gaskets and head warp.

If the serpentine belt pops does that make your car run hot?


Have you checked your fans? they both need to come on. Sometimes only one comes on and that will make your car overheat. You might want to check the bleeder valve on your intake manifold., usually located where the upper hose goes into the motor, near the thermostat housing. Sounds like a fan problem to me

Running hot


When you say its running hot..is it "overheating" which would ruin your engine?
If it is running warmer than it should you may need to replace the thermostat..
If it is boiling over just a little when you park (making you THINK that it is running hot)...you need to replace the radiator cap, as the pressure seal is not working.. which will make it appear to be running hot...but its not...... the thermostat cap is a $5 to $10 item.... need more info

95 ford mustang hot outstide quits running


For starters have the radiator and coolant system flushed which may help cool the engine better. But when it gets too hot, motor oil loses it's viscosity ( thickness and lubrication properties ) and gets thinner. Especially in hot weather you should make sure you have good oil and make sure you dont run it low on oil. On the flip side make sure that it's not overfilled because this will blow out the seals and you'll have much bigger problems than no power. Hope it helps!

'98 Buick Park Avenue running hot


replace the thermostat just to be safe. not to do so is what i call to gag on a nat and swallow a hog. then pressure check the cooling system to make sure it is not making pressure above what is on the radiator cap. if it is you may have a blown head gasket. make sure yer not gettin antifreeze in the oil.

Idling high and running hot


did you change the thermostat? and it sounds like you have a vacuum leak that will make it idle high
