Late 2U water pump leaking

So far as I know, most pumps have that weep hole as an indicator that the seals are leaking. Cat might have a pump service kit with all the the gaskets, seals & what-not.

Admitting I am not a mechanic by nature and miss the obverse,I beat myself up with a leaking water pump in a D6.The problem was the injector per cup seals leaking gas into water jacket and pressurizing radiator and blowing coolant out weep whole on water pump. Just something to consider since you stated water pump is not that old.

Hey OilSlick,

I hate when that happens!!!

Ray, thanks for your observation, I hadn't thought of that angle.

However, should not the pressure relief of the cooling system taken care of that problem?

Remove the pump assembly (unbolt at the timing gear case) and get it on the bench. Tear it down for complete check. Mechanical seal is on the back side of the impeller accessed from one side, bearings and oil seal accessed from the other side. Process is well described in the D13000 Servicemen's reference book. I'm surprised you may not have one after all the work you did.

OM, yes my service handbook covers the later style water pump but my parts book only goes to 13,000 so it doesn't cover it. Would you happen to have a parts book scan for a 23,000 D82U water pump so I can order parts?
