What is the OEM brand sold by dealer for 99 ML 320 water pump?

MB has their OWN casting company..not available thru any aftermarket..only OE thru dealers.

However the interernals..like the bearing & seals are made by INA & at least 2 aftermarket water pump makers (Graf & Sil) use that bearing & seal assembly.

What is the advisability of replacing the water pump on my 1999 ML 320 with 117K miles on it. It is not seeping but I have the shroud, and fan with clutch removed so I can change the bearing in the A/C clutch pulley. I found the idler pulley was noisy so I will change that too.

I just was thinking with the pump so easy to change with everything already apart I should go ahead and do it since the vehicle has over 100K on it.

Any advise?

Ron -- just FYI. On same vehicle as yours, mine was replaced last month. It wasn't because of leakage but , instead, the tech found considerable slop in bearings - he was thorough. Brought the old pump home and confirmed bearing problem. Seemed like there was a lot of movement so am probably lucky it didn't start leaking on last trip.

Vehicle has about 120k km on it.

I replaced mine at 60K (last year) with a Graf purchased from Phil. so far so good, it came with gasket already so you don't need to buy any gasket. fitment is perfect.
