I have a 1962 CJ5 w/F head. I removed the heater core and am not re-installing it. Do I need to connect a hose from the water pump to the cylinder head port on the rear of the engine? I think this hose is not right for my situation.

Willys Jeep Parts Tech:
If you are not using it, then you can just plug it off.

Is this used on the F-134 Engine? It says ''BYPASS'', is it needed if Im using a heater? Thanks

Willys Jeep Parts Tech:
Yes, it is used on the F head engine.

What is the ID of this hose??

Willys Jeep Parts Tech:
1/2 inch
