Other than the bleeding tips you already got let me add: If the pump bearing is worn severely the shaft will rotate off-center and grind out part of the pump housing, while letting coolant backflow in the other end. The result is reduced pumping effect and both a broken pump and pump housing. (Note these are two different part numbers. I've still got some FS) Additional warning: Many unscroupolus or ignorant mechanics take the easy way out and replace the correct waterpump (harder to find) with the more commonly available Golf/Jetta one. This causes overheating. THe three last dead Diesel Vanagons I inspected had most likely overheated and died because of this. There are also big quality differences between the aftermarket waterpumps. > questions 2. and 3. remain: > 2. timing belt not tracking properly > it's riding @ 1/8" to the REAR and has worn off @ that much of its width on > the crank and tensioner flanges BAD, BAD, BAD. The Diesel is an interference engine.

Lubing the shaft might help for a while. Very carefully bending the lever upwards often solves the problem. Dissassembly or violent acts likely lands you with a $500 pump rebuild.
