[DMCForum] Re: Overheating problem

["cruznmd" <racuti1@xxxxxxxxxxxx>]

True..I was mistaken that pressure would keep fluid from flowing into 
the coolant bottle, but I've still seen vehicles blow the radiator 
apart because the cap failed to vent.

Now that I think about it, that was a combination of problems though. 
The truck in referrance overheated because of a snapped waterpump 
belt. Then the cap failed to vent and popped some seams. 

But I've noted that some folks are leaning towards the stuck 
thermostat theory, which I also like.

I dunno...I guess I have a lot of balls posting my advice when I blew 
up my own engine and have done a questionable repair job.
