[Mg-t] Cooling system

[LAF48 at aol.com]

 Pressurized cooling systems were not designed to prevent over heating, or 
loss of coolant due to expansion or loss of coolant due to boiling. A 
pressurized system helps prevent blown head gaskets, by keeping the coolant @ the 
exhaust valve pocket a liquid, instead of a boiling vapor, even when the 
engine temperature reads 160 degrees F. Both pressurized & non pressurized 
systems will push coolant out of the overflow tube if overfilled, coolant should 
be 1 3/4" or so below the filler neck. </HTML>
