[DeTomaso] I blew up my car

[Peter Kovacs]

I had a similar experience shortly after I picked up my 73. The serpentine belt cut through a water hose. I replace the pieces, cleaned up the mess and drove the car to Patterson. I had no idea about burping out the air. Pegged the guage and the block got so hot it seemed to smoke the paint right off the engine. Thing was...it was an aluminum block with no paint. Many conversations and heat cycles later, the air was burped out and it hasn't overheated since.

AJ,

It is not uncommon for a system that has been empty to get air pockets that keep the coolant from circulating. I always watch the temp gage and when it gets to about 220 F I shut it down and let things cool off. Then it usually takes a gallon or more of coolant. It helps to leave the heater hose that feeds from the block off until coolant runs out but there can still be some air. Just keep cycling and it will eventually work it's way out. I don't understand why the overflow tank would fail. It should be vented and not see any pressure. As others have said don't quit now you are almost there.
