If there is a leak between a combustion chamber and the cooling system, e.g. a broken head gasket, then pressure from the combustion chamber will enter, and pressurize, the cooling system. When the pressure goes over a certain pressure the safety valve opens and cooling liquid is ejected from the cooling system reservoir. Depending on where a head gasket is leaking you can get unwanted contact between combustion chamber, cooling system, oil system, and the outside of the engine. > I mean the reservoir is supposed to be > pressurized anyway correct? Yes, but only from temperature rise in a closed system. Not from combustion products. -- G–ran Larsson http://www.nospam.com/saab/
