It sounds like you have air pockets in your cooling system. Those engines have bleed valves strategically placed about the engine. At the radiator filler neck it looks full but in reality you're low on coolant. They're a bugger trying to eliminate the air pockets. That's what it sounds like with the informaion you gave. Good luck!

Car overheating replaced everything and still overheats


try a pressure test on the radiator while it engine is running.. If your head gasket is broken the compression of the engine goes into the cooling system. If the pressure rapidy increases it would indicate a head gasket problem.

Have you replaced the intake manifold gaskets? These engines have a history of leaking intake manifold gaskets. Water leaks into the intake and is burned off in the cylinders. If the engine overheats enough times, you will eventually blow the head gaskets.

Start by performing a compression check to make sure you haven't blown the head gaskets. Then make sure the car is really overheating (i.e. check the temperature of the engine with a infrared thermometer (they are cheap at Harbor Freight).

If it is really overheating, and you've really changed everything else, you need to change the intake manifold gaskets. Be sure to get the improved gaskets from the parts store (they have a metal core with rubber coating).

Leaking, overheating --- *fixed* then puff of white smoke 1 week later


I'm not taking sides in this. So what I am going to say is more or less neutral.
There is a big possibility you damaged the head gasket when the engine overheated last week. The dealership would have no way of knowing this if it was not yet leaking into the engine when they replaced the water pump.
Once the water pump leak was fixed, the system would be running under normal pressure which could finish off the weak head gasket.
You can not see a damaged head gasket without removing the cylinder head. And you have two heads with two gaskets.
So, IF the head gasket is now blown there is a good chance they did not know it last week. It could also be a cracked cyl head or leaking intake manifold gasket. Or all of the above.

Ok. guys. i am losing coolant. it is not showing up in the oil and i have no external leaks. i did replace the head gasket and all associated gaskets about two months ago. also have changed the upper and...


If the coolant is leaking at the head gasket or the intake manifold gasket slowly, then new gaskets will have to be installed. The bubbles coming up is a bad sign that the seal of the coolant system is bad or it's overheating the coolant to the point that it boils over.

The overheating may be due to air or vapor in the cooling system not allowing fluid to flow freely.

Did you put a 50/50 concentration of coolant to water into the cooling system?

Also, check the fan to see if it is turning on when the car is at operating temperature at idle.

May need to be flushed out and new coolant installed to increase cooling efficiency.

Good luck on this repair.

Hello I have a 2000 Cadillac Deville if the intake manifold gasket is bad would that cause my car to overheat?


It can cause it to overheat if it is leaking coolant into the engine or outside of the engine. Replace your thermostat and check your oil for water and your antifreeze for oil. This will confirm if your head gasket or intake manifold gasket is leaking. Check you water pump for leaks and and make sure your coolant reservoir and radiator are full with antifreeze. Another possibility is your catalytic converter is plugged up

1996 Pontiac Grand Am overheating


If its the 3.1L it could be your intake manifold gasket , the material used for the gasket does not react well with GM's Dex-Cool antifreeze. The leak may not be apparent at first, but I would pressure test the cooling system. If you look at the front of the motor by the belts , try to peek down at the intake manifold and check for slight seapage to an obvious leak.

If its either of the Quad-4's they were notorious for heads warping or cracking.
