Cheers Moparts. the water pump is knackered in my 2001 ram. is one brand better than another, or what should I look for. i see them from $30-100+ for sale. I already changed this once maybe 7 years ago don't remember where I bought it.

appreciate the advice, happy Sunday

I'm assuming that mag pump is a different style than LA pumps? otherwise I'd get a cheap parts house 8 blader & weld an anticav plate on it

i think its different?

that's what I thought. I've always had perfect luck with parts house replacement w pumps & wouldn't hesitate to buy a cheapie (for that app)

Flowcooler made a Magnum style reverse rotation coolant pump that flowed about 30% more at the same rpm.

Nascar cooling guru Howard Stewart wrote many years ago on his board that GNB brand replacement pumps were generally better than others.

In 1992 Chryslers official press release on the then new Magnum 5.2 V8 bragged that the new coolant pump was 100 gallon per minute with an efficient design.

To me, as a mining engineer that has looked at hundreds of pump insides, the stamped steel impellor of the Magnum factory pump looks cheap and crude.

Some of the Magnum stamped steel impellors have failed from cavitation damage when the antifreeze mix was not maintained by owners.

The impellor of the Magnum V10 coolant pump looks like a better design but will not fit the V8s.

Dont waste $$$.Just go to the parts house and get a reman or new one.Ive used plent from Advance and AZ at the shop and onour own stuff and never had a problem.Ive even got some like for my 3.3 when I had it that were Mopar in an Advance box.Just a lot cheaper.Rocky

Appreciate the help. Just to follow up... Got a new pump from autozone for $60. Swap took about 2 hrs.

The old pump bearings were bad and making a hell of a racket. I was shocked how the noise carried through the whole drivetrain; at first I was almost certain it was the transmission or transfer case. Sure glad it ain't!!
