Hi All,

I've been following this thread since I have similar symptoms on my 1987 300TD. Recently, the temp has started climbing on hills. By flooring it going up a long hill I was able to get it to just touch 100 degrees C. The temp drops almost as soon as I crest the hill.

I took it to my mechanic. Since the radiator was original with the car, we assumed it was probably due to that and he replaced it with factory-new.

Sadly, as I drove home last light, it climbed near 100 again just going up a bridge (the Kosciusko on the BQE for those who know NY's outer boroughs).

For nearly a year, the temp gauge has sat just above 80 and wouldn't move to matter what.

I'd like to check out the water pump as suggested in another post but I'm afraid I don't know what the water pump looks like. Could anyone describe where in the engine bay it would be?

Thanks for any suggestions

Tim
