We have never had any issue.....We have a Alum. fan on several of our
cars. be sure belt is not very tight. Our Mopar pumps turn very easy or
we replace them. we run 14 tooth pulley instead of standard 10 tooth.

Most of the Drag you feel on the new pumps without fulid is the seal creating the Drag.

Yep, I understand that most modern water pumps use mechanical seals. The pump was new when installed.
I always keep the belt loose.

I’ve used an electric water pump drive with a small aluminum flex fan for years. Never had a problem. I believe Moroso offers a different drive pulley that will change the pump speed.

You can get a motor that has 4 posts with 2 of them being the same center to center as the Moroso 2 post motor but is a more powerful permanent magnet motor from W. L. Walker 918-583-3109 or wlwalker.com


The part number is 18051. This is the company I work for. We sell stuff to test measure or sample oil but I used this motor on a few friend's water pump and they run much faster also. Depending on the input voltage they will run 2100-2250 rpm. It has the same 5/16" shaft. Just grind down the 2 posts that you don't need. Just an option to consider. Looks like they are about $11 more than the Moroso motor.
