C8.3 Water Pump, what brand?

I need to buy a new water pump for my 8.3 as I noticed the weep hole is leaking pretty good now. My question is what brand pump is everyone using? I can find cheap no-name, I tend to avoid those on all my repairs. I found a gates, and some others. What is the go-to "won't be redoing this in a month" water pump folks are using?

Where do you order cummins parts from? Direct from them?

Well I ended up going with a Gates. The Cummins was $200 and the Gates was $100. The Cummins only had a 1 year warranty and the Gates had Lifetime. I have had good luck with Gates products in the past so hopefully this is another one. Luckily I have a side radiator and this looks to be a very simple install.

I am kicking myself as I just flushed the coolant system a month ago and was in a hurry and did not do the pump...I will drain the coolant into some clean buckets and hopefully reuse the Zerex OAC I put in!

When I had my radiator ruined with road debris and had to have it changed I insisted that the Cummins shop replace the water pump and thermostats. The engine and radiator completely drained so to be able to move the coach so a tow truck could hook up I tan a hose from my wet bay faucet to the surge tank and just pumped fresh water through the system. I also insisted on a complete flush prior to adding new coolant. Seemed like the best time to do it and the cost was minimal compared to the cost of the radiator and labor.

You probably could not have gotten a cummins water pump now unless you found someone that had one in stock. I had to replace one a month or two ago on an 8.3 equipped peterbilt at work and couldnt get a cummins one from MHC Kenworth or Cummins Atlantic. They both said cummins is having major issues getting stuff out of the warehouses due to covid. Everything is backordered. May be better now but I still have several parts ordered from weeks ago that I am still waiting for. My shop down in SC has been waiting for injectors for an ISX12 for months.

One of the first things I did was flush the coolant system really well with multiple rounds of distilled water and then switched to OAC coolant. I was racing the weather so I skipped the pump and thermostat. Now I'm kicking myself

I have had several covid related issues with construction supplies too. Don't get me started on lumber issues

I was confused on how I would even order the cummins one. I found a few listed on ebay etc but was not quite sure how to order direct from cummins. Perhaps they only sell to repair shops?

I would guess that I will be fine with the Gates. Worse case it fails but it look like about as easy of a repair job as it gets!

Who is the local cummins branch? Out here (Charlotte area), its Cummins Atlantic. You can just go to the parts counter, get what you need and pay with a credit card (since you wouldn't have an account). I also get Cummins parts from the local Kenworth dealer (MHC). Gotten stuff from Peterbilt too when they are the only ones whomhave what I need in stock. They'll all sell parts to anybody.

You can also google the PN you found too and buy it online (though it might be more expensive).

John,

I'm in Lexington just a few miles from you. Have you bought from Consolidated Truck parts there in Rockwell? They may be able to get what you're looking for. I've bought parts from them several times and we're very reasonable and seem like a good group of guys. They gave always had or got very quickly what I needed.

Ahh okay, I guess I didn't think of that as I shop online pretty much exclusively nowadays for projects that I have time to order and fix later. I know there is a cummins shop around. I've seen them but never worked with them. I will check out their pricing (and maybe a few other shops too) next parts I need. Thanks for the tip!

Well, as a matter of fact, I'm in Rockwell and know those guys well. When Cummins told me they couldn't get me a water pump, Consolidated was my next call (and they had one the next day). I got all my exhaust pipe parts there for my coach when I changed from the factory 4" muffler to a 5." They have a lot of stuff in stock over there and you can usually make something work.

John that's exactly what I found. Always had the stuff to make it work. I wasn't sure they could get Cummins parts but it doesn't surprise me they can. I'd much rather buy from them over the $$$ dealer.
