why would a waterpump break like this!?!?!


Recommended Posts

No not the head? The waterpump it self.when you buy a new one it don't come with a pulley Ibought it new put the pulley on. There's 4 bolts that scew threw the.pulley into the pump.they snapped and grade.of bolts idk.stock ones?

I mean the heads of the bolts. I also thought you broke the entire water pump off the block lol

Did you use loctite on the pulley bolts or not? Pulleys don't cause bolts to break. I've seen bent pulleys, broken belts, misaligned pulleys, etc, but none of them ever broke a bolt. Bolts backing out would cause that kind of carnage, just a matter of time.

Loctite? Yes or no?

Either the pulley was warped or you tightened the bolts to damn tight and then once it got hot and load on it snaped them.

.ohhh hahaha yeah the head of the bolts broke off lol my bad! It was probably what everyone else is saying the must of backed out.a bit and the pulley couldn't hold the load. broke as you can see in the pic of the pulley and took the. heads with it and cause some other carnage as well

I didn't use lock tite. on those bolts I didnt think I needed to but its a lesson learned everyone makes mistakes.which mine was a a big one

Ok then. I'm not trying to bust your balls, just that it seemed to be the most likely culprit based on your description. If you didn't use it, then I'd say about 75% chance that was was happened. Like you say, lesson learned. You'll know for he next time. I once left the intermediate shaft of the oil pump out of an engine I was assembling late at night. Had about $8000 invested on an engine I had built completely by myself. Fired the engine up and ran it with no oil pressure during breakin. Had to rebuild it all again. Shit happens.

What is that pulley make of? Did you use a torque wrench you know they weren't too tight, that is what I was getting at, I have tightened plenty of bolt I thought were fine and then snap off cuz just too tight.
