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 & Hepu brand water pumps are both metal impeller high quality oem suppliers
I also used a kit from FCP Euro about 8 years ago and it included a HEPU water pump that worked fine for 7 years until I dismantled that car.
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.
my hepu has been in for 9 years with zero issues
i replace with OE saleri pumps every so often and havent opted for a stewart pump.
I had a Saleri pump. I changed it at 100,000 in 2013 and bearing was good at around 145,000 in 2021. I inspected it with a camera. It appeared to be leaking at the gasket.
I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.
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.
a Hepu which went seven years/60,000 miles before it started leaking. I think the additional mass of the metal impeller put more stress on the bearing and seal.
