Hey,

Ok i have a water pump that has two hole fr heater hoses on it. One is big one is small. can i connect both heater hoses to the water pump or do i have to put one ont eh manifold. The reason i ask is because typically a manifold will have a spot for the heater connection adn the temp sender, but mine only has one spot. I know i can jsut get a water neck with the spot for the temp sender. but thats 10 bucks and 5 minutes of work that i m too cheapo and lazy to do if it aint necessary. Plus it looks cleaner without a hjoel in teh waterneck.

So basically what i have is one heater hose conected to water pump adn one connected to intake manifold. I wantto move the one on the manifold to the other hoel ont eh water pump. will this work or are both spots on the water pump like gonna be workign against each oher nad not movign any fluid?

thanks for any help,
Jordan

It doesn't say what kind of engine/car you have but most old ford pumps have two nipples on them. One is for heater hose and the other is for a by-pass hose. I believe flow is in the same direction out of both, therefore you could not switch the intake hose to the by-pass niple on that application. The return would have to go to the intake.

Actually I believe I was backwards there, I think the flow is into the heater core from the intake and back to the water pump, making that a return nipple. And the by-pass allows a controlled amount of coolant to by-pass the t-stat back back into the water pump, also making that a return nipple. So they're still flowing the same way I think I just had it backwards first. Somebody will have to verify if Chevy is the same.
