well i did what i said i would and the problems still there, so im just gona replace the headgasket and spray it with copper before i install it.

its crazy cause the car drives like nuffins wrong, no over heating or anything and ive been driving it for miles, even racing mustangs and cadi's....lol

I had that problem and it was due to air bubbles. Have you recently changed your coolant? Maybe you didn't bleed it well enough.

I just start my car with the rad cap off and let it idle for a while.

Yea a bad thermo and rad cap can lead to a blown head gasket. Here is how I bleed my system, gotta be carefull. I like to drive the car or let it idle till it gets to standard operation temp then turn it off and let it cool a little, not to much. Pop off the rad cap, be carefull cause if it is still to hot it will spray. With the cap off start the car and watch the coolant buble and add as needed. You need to get the system hot enough for the thermo to open. A air bubble can get trapped behind it when you replace it if you don't bleed the system. HTH...Matt

Do NOT get a higher pressure radiator cap!!!! that will allow the coolant to reach even hotter and possibly blow a hose! just remember the more radiator cap psi the hotter it'll get/hotter boiling point... stick with OEM recommendation!


also if you test without a thermostat... do NOT drive the car like this... it may run colder (lucky) or may overheat like crazy! there is a reason for the thermostat to close while even at normal operating temp.. the amount of air hitting the radiator will cool down the coolant, well if your running no thermostat then it won't have enough time to cool it down.. see what i'm saying??

my suggestion since this is a question... bring it too a well known shop

im not running without a thermostat

but i bleed the systems a while ago...the f22 has a bleed valve/bolt on the thermostat housing, so i bleed it and bubbles came out for like 1 minute.
ill see if if helped tomorrow

Just seriously bleed the living ---- out of it. I took the cap off and let it idle til it warmed up and at op. temp. revved the ---- out of the engine until all the bubbles were gone.
