After driving long distance when i stop my car push water out off the radiator and coolant continer


Blown head gasket may cause this to occur as exhaust pressure goes into cooling system and builds up pressure over time

I have a 97 cutlass supreme SL I have replaced the thermostat, water pump, upper and lower hose and temp sending unit and flushed everything but it still overheats. Why?


I can think of a couple possibilities:
Blown head gasket, leaking into the coolant.
If it's not blowing water out, the temp sensor may be bad.

What are signs and symptoms of a blown head?


white smoke out the tailpipe and the smell of anti-freeze in the exhaust gas. an engine that over heats either only at highway speeds or town driving, when all other things like, rad cooling fan working properly, thermostat is working properly, no external coolant leaks. the spark plugs may show signs of coolant on them. just some things that are indicators.

Oil in the radiator


Oil in the radiator might be automatic transmission fluid cooling lines that run into the radiator that are leaking. OR its stuff that is collected over time if the cooling system was never flushed and cleaned out. Its usually antifreeze in OIL not the other way around which means blown head gasket or leaking intake gaskets.

Car running hot


Probably a cracked cylinder head or block, or both. Or the head was warped and the head gasket has blown again.
When the engine gets very hot the gasket expands, and after a few times it will not return to its original shape.

I HAVE 2004 MONTE CARLO. THE HOT COOLANT TEMP LIGHT HAS COME A FEW TIMES. THE HEATER ONLY BLOWS COLD AIR FOR A BIT AND THEN EVENTUALLY HEATS UP. THE CAR NEVER SEEMS TO RUN HOT THOUGH. I HAVE BEEN TOLD...


A blown head gasket is usually easy to confirm. The head gasket prevents the engine coolant and oil from mixing under the head. If you have a blown head gasket, you should be able to see bubbles of water/cooland on the dip stick when you check your oil.

I do agree that with your heater taking a while to get warm, it probably has some build-up in the system that needs to be flushed out, before it causes other issues.

Best of luck!

Oil keeps getting in to the water


if thats the case you should have water in the oil also, that means you have a blown head gasket

Blown head gasket


The only way and fastest way to do this is by the book, after replacing the head gasket find some used oil and get some crankcase flush, mix it and run the car for about 5 minutes and change the oil, add a Rislone quart.
