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.
Cons: leaking from same spot
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.
Pros: worked fine for years
Vehicle:
Volkswagen Phaeton
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.
Cons: started leaking, shorter lifespan
Mileage: 96560 km
my hepu has been in for 9 years with zero issues
Pros: 9 years zero issues
Am pățit la fel dar cu o pompa Hepu, a mea a avut un sunet înainte să crape și la 120km/h a cedat axul, similar cum a fost a ta.
Cons: sunet înainte să crape, axul a cedat
If the hepu water pump I put on my 3.0T is anything to go by, I don't know that I would recommend them for chains.
Cons: not recommended
Vehicle:
Audi S8
I put a Hepu water pump in about 20k miles ago.
Cons: failed prematurely
Mileage: 32187 km
Hepu pumps are the best.
Pros: best quality
Water pump if stock would have a plastic impeller known to fail, but you can find metal impeller options from Graf and Hepu brands and from other aftermarket brands too.
Pros: metal impeller options available
Cons: plastic impeller known to fail
