Coolant system Flush

[tjm]

My water pump started leaking after 4 years (gates brand Im pretty sure). I now have a dayco, they recommend a flush before install. Is Prestone Flush Solution acceptable for the 5.9L?

Why didn't you buy the OEM pump for 50$ something?

I used the Prestone last summer.

Because its $273 on Genos

Sorry for that, it seems that Genos doesnt carry the recall Pump anymore. That was such a bargain.

273 dollars for a water pump?
Ebay... 68 bucks oem

Gates Water pump for that truck is 50 bucks from Geno's..

same pump is 36 bucks on Rock.. and if you are a real cheapskate they have no name water pump available for $11.51. no sense in paying 200 bucks for what is a generic piece of legacy equipment.

you can flush a cooling system with citric acid and water if you have it available ( I use citric acid in my water softener but any cooling system flush will work.)

Hmmm, I just put a Geno's Gates pump on my truck.
Ran plain water till I got around to changing the pump.
Started leaking when we were camping in central PA & an ole timer told me to loosen the rad cap so no psi would build. This drastically reduced the leak so we could get home. Though for-sure I was going to have my 1st tow....

Are you saying the new pump started leaking?

 

[promisedland]

No, the old one leaked. Bearing wear.
Prob replaced that one 8yrs ago.

Can the Higher flowing 6.7 water pump work? I've heard this is a good swap.

Bought my 04 brand new. I've probably went through 3 water pumps in it in 230,000 miles, including the original. The original lasted the longest. The second one was a Gates and I don't remember it lasting real long. Maybe a couple years.
I used to have issues with the belt and the tensioner failing. Since having the engine rebuilt after a valve seat dropped, I made sure the installer lined the pulleys up perfectly. Haven't had that issue since.

Yes it works flawless, i installed one of these 50$ OEM recall pumps. And I have to say I feels good to have an OEM Cummins water pump again.

Might be able to find that pump here.

so I put on the Dayco. The gates lasted 4 years. OEM ~16 years or 80K miles
