ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for

not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin to
