Why would a water pump be run off of the timing belt?

Electric water pump control

Electric fans are now common on cars, both aftermarket and stock. The advantages in horsepower, faster warmup, and hence emissions are well documented elsewhere. The same reasoning can be applied to justify an electric water pump. Is there as much…

Is there any way to determine when a water pump will fail?

Is there any way to determine whether a water pump needs to be replaced before it fails completely? I realize that if it dies, then I'm not going to get far. Am I better off waiting until it does than trying to replace it before that happens? I know…

Why would a brand new water pump make noise?

Many of you followed the saga of the noise coming from my timing belt area after I changed the belt and the water pump. The noise eventually went away on it's own, and I think we determined with a pretty high level of certainty that the source of…

I'm changing the head gasket on a 99 ranger. I don't know why it overheated in the first place. There has to be a cause, right? I was cleaning up the top of the engine block to put the heads back on and noticed this hole in the water pump…
