Water pump Saleri or GRAF

I binned off my original water pump which was now made of cheese and spraying my engine bay like that and bought an SIL Saleri (Italian) pump online. Metal impeller and comes with the seals kit for it too. been perfect for years.

Graf here. 15k miles/ 2 years, no problems.

I use on my 12v and 24v VR6 engines, Eurowise aluminum thermostat housing and 42DD stainless steel crack pipe. Water pump I use GRAF or Hepu for its metal impeller.

If it *is* leaking you might want to consider replacing it with a Graf alloy-bodied pump which won’t be affected by heat and exposure to oil, the usual causes of eventual failure of the plastic pumps.

I replaced a perfectly functioning OE Saleri at 12 years/90,000 miles. I will stick with the OE Saleri even though it has the plastic impeller.

Graf has been pretty good to me.

I've also had a Graf I think it was, it did have a metal impeller, which started leaking after 7 yrs.

what I had problems with is with Graf water pump, that was included as part of FCP euro cooling system kit, water pump seal around the bearing started pouring coolant like a waterfall after only 11k miles, I replaced it with a Stewart pump

The Saleri started leaking at the shaft so it wasn't an issue with the gasket. The Saleri had a plastic impeller while the OE had a metal impeller.

the metal fins are spot welded like shit on these cheap metal waterpumps. my graf pump also started to leak from the weep hole after a year too
