Second Flowkooker in a row. Before that 2 Mopars. Before that 2 NAPA. The NAPA ones were junk and started making bearing noise. The 4 Flowkoolers and Mopars all started leaking from the weephole. I'm wondering WTF.

Are you using the correct belt? Is your clutch fan in good shape? The only thing I can think of that will continually kill water pumps is too much stress on the bearings.

I was running the Mopar efan but I switched to clutch fan about a year ago. Doesn't seem to matter. The Flowkooler instructions say the pump might leak through the weephole at first until the seal laps in. I'm going out to look now.

She ran great yesterday. Never went about 200*. 70* day.

Know you know how to tension a belt but are the pulleys lined up straight on your 5.9 transplant? Any pulleys replaced like PSP? Bypassing your AC compressor which doesn't work? Just digging for suggestions....

AC compressor is long gone. I have the recommended shorter belt.

The belt is aligned perfectly and there is no obvious wear on the belt.

The new water pump is not leaking! See how long that lasts.

Same truck for all these pumps? You may have some casting sand or other grit moving through the system

Could radiator stop leak cause it?

Never.

I replace the coolant that I drain when I do the water pump, which is often.

Guess its time.

Give it a shot. Im not 100% positive but I could see some of that filler gunk getting places where it shouldnt be and causing some issues
