Hey all you aint gonna beleive this one. I have a 91 s-10 blazer 4.3 auto.
Last nite at the boat ramp, while putting the boat in the water, my radiator
popped a leak and coolant started GUSHING out of it. I pulled the truck off
the ramp, opened the hood and found the leak. It was the plastic drain
valve. It popped out of its hole like a cork gun. I have never heard of such
a thing. Gotta love the Engineers at GM for this high quality idea.
I found the replacement at autozone for 3 bucks, got the truck home and
this morning flushed out the coolent system and changed the t-stat.Has
anyone else had this problem ? If so how do I prevent it from happening
