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: What are the part numbers for the gasket and the hardware kit? I think my water pump is Ok. Am I being penny wise and dollar foolish? Thanks. ~P.

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
Question By: Luther park on Oct 13 2018 10:02 PM
They didnt use a spacer originally. It bolted directly to the water pump.

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.
Question By: Tim on Aug 5 2017 11:27 PM
It shouldn't matter. This is correct for your 4-134 Motor.

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.
Answer By: Willys Jeep Parts Tech on Apr 27 2017 6:19 AM
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?
Question By: Anonymous on Nov 26 2014 12:00 AM
This will have a plug in it for you to run a separate heater or bypass hose.

Questions: But all new cooling system in my 49 cj3a. Is running really hot and not cooling. And suggestions? Did notice after shut it down awhile top hose real hot. Bottom cooler if that means anything???
Question By: kevin on Feb 23 2014 12:00 AM
I would check your thermostat and retainer. Then go to water pump, then check radiator.

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.
