Let it sit in your driveway and see if there is a coolant drip under the radiator (it has to be running). Its kind of wierd that the cap is not pulling fluid from the reservoir.

 

my rad does not lose ne fluid when it sits there. i well try running it tommorow. i heard that it could be the head gasket???

In that case, you would have lots of white smoke coming out of the tail pipe. Did you make sure and check real good around the radiator for coolant?

 

Hi
Its not blowing any smoke out of the exhaust. I have checked the rad when the car is not running and it doesnt have any leaks. I have also checked it when running and i can not seem to see any leaks either. I dont know what it could be other then a head gasket.
