    1996 Grand Prix SE, also noticed after the over heating, twice noticed a milky film around oil cap. Losing oil

    We've tried to bleed the system out no luck. he even took the thermstate completely out and it still did it. Do u think it could be the gaskets???? My son doesn't think that's the problem. I don't want to see them tear it all apart again and that not be the problem. Maybe just putting a whole new motor in would be wise. The motor has 190,000 miles on it.

Whats really gunna **** you off is the part you probably need is about 5$. Inside the radiator hose is a spring loaded "switch" that supposed to expand when it becomes hot and let radiator fluid thru. Sometimes these springs freeze up and don't let the fluid thru. IE probably your problem.

Thermostat is your problem because your current thermostat don't open when the water gets too hot it should circulate

Why wont my car wont hold water or anti-freeze and i cant figure out where its coming from or even going?


its possible that the engine is burning the coolant which would not show either by causing the oil to turn a milky color or leave a puddle were you parked. it may be just a small problem at the moment not causing the car to overheat. have the head gaskets checked for damage with a head gasket test. it could also be a possible intake gasket leak causing the coolant to be burnt but not leak into the engine oil. just somethings to check out.

If you haven't replaced the thermostat yet, try that next.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Car is over heating and going into the resovier. Replaced water pump, thermostate twice. Someone in this forum mentioned a spring loaded switch. However this is a 3.1 motor Pontiac Grand Prix SE two door....


If you have a white, milky fluid, you have moisture in the oil. No question on this. You may try retorquing the top of the engine (heads, intake, etc.). Change oil and filter. Now if this has electric motors for cooling (fans), make sure they are working. Don't overlook the obvious. Check the radiator cap. Cooling system must have pressure to function right. A bad cap could cause overheating.

Good Luck

Are you sure you put the thermostat in the right direction? The 195 degree copper bulb shold be on the bottom side. If it is a stock one.

1996 grand prix se running hot


it sounds like it may have air in the system there should be a bleeder valve for the coolant also if it ran hot you may have a possible head gaskt problem i would try bleeding the air out of the coolant system and if problem is still there you can buy a kit to check the head gasket it hooks to the coolant system and you pour a liquid in it and if it turns from blue to yellow it has a head gasket problem
