you can tell by looking at it,
coolant runs one the outside of the tubes(center section) normally a large hose connection. and raw water runs though the center of the tubes. the raw water inlet and outlet may be on the same side depending on how may pass it its.
I can't look at it! I need one and a guy has one for sale but it has 4 outlets. Not sure if it's the one i need. The Part# in this thread is the right one but i can'r tell if it has 4or5 outlets?
Mine has (3) for the fresh water side....[(2) returns (1 for ea manifold) and (1) for the return going to the circ pump] and (2) for the raw water side (input and output).............for a total of (5)..............does that make any sense?
Yep i got it Tony, My aplication may be different though 1979 so i need to make sure the one the guy has is right. The part# is right but can't tell by the parts picture i had, how many outlets there are. I was hoping someone else had a different parts picture or specs on it to tell. thanks
