Thanks Mike---then one more question. Does it take a different cap to

The reason it will push coolant back into the cooling system is the lower pressure created under the radiator cap as the system cools down. Coolant expands as temperature increases and the inverse occurs as it cools. This causes the lower pressure situation under the cap.
