Engine Water Pump

[rustonrust]

Anyone purchased a water pump online recently? I have heard there are many different versions that fit differently and need to compare side by side with old pump. Wondering if this is true and I need to take old one into shop to compare before buy? Or if ordering online has worked out for others. 85 CJ7 with AMC 258 i6 / 4.2l . Thanks.

You probably going to need to know what direction the water flows. I got mine at napa

I've bought a ton of em off Rock Auto over the years never an issue. Just get a quality brand

Ok thanks for the response guys.

The easy way to tell is what type of belt system you have.
V-Belt = Standard flow.
Serpentine Belt = Reverse flow.

I don't think I've ever owned a serpentine belt CJ

Hi yes, there are two types of pumps for sure if you are working on a AMC 258 i6 / 4.2l ? I removed mine took some pictures of it, then compared it with the pictures at the online stores. I found out the hard way, and have a new one- not matching my AMC 258 i6 / 4.2l somewhere sitting.

I just put one on my 81 from FlowKooler, reverse flow for Serpentine belt. Beautiful build quality, CNC impeller, higher flow, Japanese casting, CA company. Super fast shipping and nice Website

I'm just here to vent because I just had to ordered a second water pump

A little background info, I've had my CJ for 15 years now. At some point during that time, I remember changing the water pump, there's been a lot of life happen in that amount of time, so I remember having some issues, but I remember getting it right and it hasn't been an issue since. About a month ago I noticed water coming from the weep hole and a distinct noise coming from the front end of the engine that sounded like a failing waterpump bearing.

So, I got online and ordered another from a very reputable...
