Re: 3. - After changing a half dozen Vanagon water pumps, I can confidently say that aftermarket water pumps don't even come close to the real deal for trouble free service. Regardless of how good it looks, if it's a knockoff, the water pump still may be the source of your woes. Perhaps the impeller deck height of your pump is too great to produce adequate flow at idle. I once had one of the highly touted aftermarket pumps which never leaked a drop nor had any detectable shaft runout (aka, slop) come up lame. It was only after I heard the screeching sound of the impeller doing some impromptu milling of the case that I discovered that the impeller had shifted axially. Now, only you can decide if you want to throw the dice with the cost of a new VW water pump on the table. Richie |
