ACDelco Gold 252-318 (12494067) Engine Water Pump

Really good pump. Love how easy Cummins pumps install. You could pay a lot more for a lesser one.

Fit and function perfect, 10,000 road miles with half pulling trailer. No problems to date.

I’m amazed that I can get something like this delivered to my front door overnight. The price is comparable to OEM replacement which I would not have been able to get on a Sunday. Went right in lickedy-split and was done in an hour including draining and refilling the radiator.

I had replaced my waterpump 7 years ago and had dead business for 2+ years due to the California "pandemic" shut down, so had put under 40k miles on it. The waterpump from Kragen/Oreilly's Auto parts. Their own brand. The new AC/Delco waterpump was superior in every way and expect it will last longer than I even have the truck. Store labels, even with "Lifetime Guarantees" are not worth the effort.

So far so good. These non OEM 5.9 Cummins water pumps only last 30k miles if you’re lucky. Trying AC Delco brand this time.

Purchased for 2004.5 Dodge Ram 5.9 Cummins 4WD Dually. Not readily available here in the UK. I went to RockAuto to get part numbers and thought I would look at Amazon.com. Amazed to find it on here. Ordered it and only paid for basic delivery. Arrived only 4 days later to my UK address. Compared makes before purchase and this had good reviews. It DOES come with O ring gasket that you need which is not very clear in description. Simple job to replace as well, give it a go yourself. Remove water(tap at back of radiator will require 2 buckets) Remove air box for accessibility, remove serpentine belt (your halfords socket wrench on square hole in tensioner) remove the two 10mm bolts in water pump, remove, clean surface and reinstall. Fill up water, carefully put belt back on (make note of belt route before removing) start her up and look for leaks and let water bubbles come out radiator before putting cap back on. Reinstall airbox. Simples. Good luck.... 2 hours max

At 66 years old, I had not worked on an automotive engine since 1976. My mechs were tied up for three weeks so i decided to order this part, took a look at U-Tube videos and attempt the repair on my 2004 Dodge Dually 3500. The pump was constructed better than OEM part, works like a charm! It took about an hour and a half, but having done it once, could do it in an hour or less now. The radiator hoses, replaced at the same time, were harder to install! (space issues)

Works well and quick install.

Très bon
