Questions: Does the 4--134 engine need a bypass on the water pump or can both holes in the pump be plugged? Originally there was a heater installed on my 1946 CJ2A, but I want to remove the heater.
Question By: Mark Watson on Aug 4 2020 3:28 AM
They can be plugged. It is for a bypass only.

Questions: My mech. Just told me that he thinks I lost the spacer between the fan and the water pump. Because the fan hits everything. 1946 cj2a. Just needs to turn fan over? Or is there a spacer? Thanks

Questions: My old pump does not have the raised "X" shaped pulley face. Just the small raised circular boss and flat pulley face. Shouldn't matter? Thanks.

Questions: This doesn't come with a plug for the second hole in the top. (My original does not have a second hole in the top just the one bypass hole) What size of plug is needed and where can i get one?
Question By: Jeremy Stanton on Apr 27 2017 2:52 AM
7372808 is typically used for a bypass hose. But you could also plug. I believe its 1/2" but will need to check.

Questions: I have a 1956 CJ5. Besides the lower radiator hose, it has an outlet for a bypass hose and another outlet for the heater. Does this have both?

This will have a plug in it for you to run a separate heater or bypass hose.

Questions: I have a industrial jeep motor but myww2 water pump seems a bit long as the impeller touches the barrel of number 1 misses out by one eighth of an inch, is the cj2 water pump that much shorter regards terry .
Question By: terry on Jun 15 2013 12:00 AM
They used the same water pump on all 41-71 Willys 4-134 engines in Jeeps. It may be something special because it is an industrial engine.
