Helping dad out with a 1982 300d turbo ( orig owner 61000 miles) that is leaking coolant from some point below the water pump. I looked under the engine area and and attempted to locate the weep hole in the pump body. I did not find the weep hole or exactly where the leak is coming from. Anyway, I am going to replace the pump because the cooling fan bearing feels worn when I shake the blade. Is there anything else I should be looking for? I checked all the hose connections and they seem OK. The leak seems to be coming from the shaft pulleys located below the pump, but its hard to tell for sure. I didn't have a ramp to elevate the car and get underneath properly. I plan on taking a ride out to his house next weekend to do the repair. Any advise would be appreciated as I have never worked on a mercedes before.
