Questions: The water pump I have on my F134 engine has two ports one that goes to the engine and one that looks like it goes to the heater. Will this part work in both holes as well as the engine block?
Question By: Michael on Apr 14 2019 11:43 PM
This fitting is for the water pump and the engine block not the heater. Thanks

Questions: On my '46 cj-2a flathead, the manual shut off valve is on the top of water pump and my bypass hose fitting is a 90 degree located on top corner of head. Is that correct?
Question By: Mike on Nov 27 2018 11:19 PM
You can do it either way. I usually put the manual shut off on the head because there is more room there.

Questions: Putting heater in 1948 Willys overland 4-134 go-devil. Have lower heater outlet hooked to right side of water pump. Upper outlet on heater is hooked to left rear engine head. The engine pressurizes(spits out fluid) hooked up this way. If you bypass the heater, it runs fine. What is hooked up wrong?
Question By: Barb Metzinger on Jan 11 2018 5:13 AM
If I'm understand it correctly you may just need to flip flop the hoses on your heater connection and the flow will be correct from engine thru heater.

Questions: where do these fit in the block?
Question By: titus on Sep 9 2017 4:17 AM
Depends on your motor. There is typically a port at the rear top of the head.

Questions: My 1961 CJ5 has a double ended threaded pipe screwed into the front of the cylinder head to connect the bypass hose to. Can I remove the threaded pipe and replace it with this? Engine is the F Head.
Question By: Glenn Frank on Aug 13 2017 3:50 PM
Yes, this should fit into your head there as well as the water pump.
