I have seen that the cooling system needs to be bled....what are the symptons that it needs to be done? My problem is that I have an intermittant cooling system leak. It does not do it all the time or even when the car is running warmer than normal. About every third or fourth time it runs I lose about 1 quart of anti-freeze. I have not been able to find the exact place it is coming from which is the real frustrating part.

 

Check the head gasket.
