Do you still have the original water pump? Those has plastic impellers that fail. Replace it with a metal impeller pump (Graf and Hepu are ideal).
I have a GRAF metal impeller water pump. so far so goof with it, i like it.
Get a new WP with metal impeller, Hepu, Graf.
Just to let everyone know, it did indeed turn out to be a defective O-Ring on the Graf water pump I installed a couple of months ago.
all graf water pumps with metal impellers are tested and balanced before packaged so why would there be any reason not to buy them ?
Just following up on this- I replaced the water pump and that appears to have resolved the issue. I have been monitoring it frequently and there has definitely been no sign of coolant leaking under the car in the area it was doing it from.
Further, the metal unit (Graf) had a sort of reptile-skin texture to the impeller fins, no doubt a product of the casting process. I spent some time with a dremel polishing the fins (because that's how I roll ) to get them as smooth as the plastic ones being replaced.
I went with the Graf in my 95 passat glx. The graf has a cast iron impeller wheel. The stock one that was in there was plastic and some fins broke off when the pump failed
My local aftermarket dealer stopped selling Graf water pumps after two bearing failures in the last month (one failure destroyed the camshaft timing belt).
My OEM plastic one broke and so did the metal-impeller Graf I replaced it with. They Graf seized up and leaked whereas the OEM plastic one just leaked.
