I Have done a pressure check of the cooling system and it holds pressure. Also took some plugs out and they were not covered in coolant!

Im leaning towards a blown head gasket but still not sure! Il do a compression test today!

I agree w/ ddgonzal, a blown head gasket will push water out of system and still not put any in the oil. A pressure check of your cooling system will tell alot. also if this is the problem, be sure to remove the spark plugs befor trying to start the veh. cuz' you can bend a rod with hydrolock if the cylinder gets full of water.

if it's spurting with force, that's abnormal. if it just dribbles out then it's overfilled.

radiator filling can be maddening and a good way to blow head gaskets.


fill the radiator to about 1/4" above the tubes, just cover them, don't submerge them completely. close cap. warm up car, put 1/2 of the amount the overflow holds and let the car warm up a little, the overflow will blow a few little bubbles. let the engine cool down, it will suck in coolant. if the overflow gets low add a little to keep some liquid in the bottle.

Quote:Number one cause: a blown head gasket. And it is quite easy to test, just perform, or have a shop perform a compression test.

Temp is fine! Really confusing hey!

so does the temp get really hot?

the boiling point of all liquids increases with pressure! If your radiator cap isn't holding pressure in the cooling system then the boiling point of the coolant will remain at 100 - 105 degrees, depending on whether you're using anti-freeze.

Pressure is not increasing with temprature????Can you eloborate??

What is the cause of this?

Car has a new radiator cap!

If your radiator cap's buggered then any pressure build up in the cooling system will result in coolant flowing straight into the overflow! Also the coolant could boil because its pressure isn't increasing with temperature!

but Im talking about 1 litre of coolant going into the overflow bottle!
