I'm hooking up my heater core pipes, and forgot how to plumb it into my intake/water pump ports...I was wondering if anyone had any pictures of the routing. I have the typical inlet/outlet on the core, and also have 2 more on the water pump itself, plus one on the end of the intake manifold next to the large upper radiator hose. and another that sits on top of the front of the manifold where the temp. sensor plugs in.

thanks guys

There should be a heater core outlet on the top of your lower manifold and cjponyparts or lmr sells the part you need its two tubes bent in a 90

So let me see if I got this straight... I have been reading some on here, and I saw that the outlet on the intake manifold supplies the hot water to the heater core...is this right? Then it returns out of the heater core on the other pipe to the?? water pump?

Sorry. I'm starting from scratch here...the previous owner had the plumbing all jacked up...hence therefore, no heater and no function of the coolant temp. gauge....nice, huh?

I'm gonna check the haynes' manual and see if there is any info. there...

Thanks for the post Mike, I have the parts to make it work, it's really just a question of flow routing...

Heres what you need it screws in a hole on the lower manifold on the passenger side front near the water pump and then youll need the two hoses that go from the core to this tube its rather simple.
