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.
Pros: 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.
Pros: not affected by heat, resistant to oil
Vehicle:
Volkswagen Scirocco
Graf has been pretty good to me.
Pros: pretty good
Vehicle:

I've also had a Graf I think it was, it did have a metal impeller, which started leaking after 7 yrs.
Pros: metal impeller
Cons: started leaking after 7 years
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
Cons: seal started pouring coolant
Mileage: 11000 km
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
Cons: poor spot welds, leaked after year
Have had bad luck with graf metal impeller pumps, multiple failures over 2 different cars.
Cons: bad luck, multiple failures
