Front of engine...passenger side away from dizzy, almost dead center from carb. Follow the black hose from Radiator.
EDIT: This is a Jeep/AMC engine, no? It is part of the intake manifold.

I've also learned that sometimes... when people don't agree with you .... its best to hold them down and kidney punch them till they agree with you

Someone eliminated your heater core. The second hose goes between your water pump and thermostat housing. Its being 'jumped'. You need a line from the water pump to heater for then back to the housing. That bolt on the back it there for a temp. Sender.

You have a new heater core put in, right? POs usually do things for a reason, in this case I'm guessing it was because the heater core was leaking all over the cabin.

An overhead pic of the engine pay will probably make it easier to show you what goes where.

The heater connects on one end where the pipe plug is in the rear of the first picture of the intake manifold. There should be a 90 fitting that goes into that hole. The hose from the heater core connects to the passenger side of the water pump. The braided hose you have from the water pump up to the intake is the bypass hose. Leave it alone. The plug on the thermostat housing is a good place to put a manual temperature gauge sending unit.


Beat it to fit, paint it to match!

Take the silver square headed plug out. That is where the line to the heater core goes. The line from the heater core goes to the port on the water pump you can see between the belt on the alternator.
