At what milage do you techs see stuff like the air pump (very costly item) and the water pump needing changing? Car is '95 E320 with 92,xxx miles. Do you recommend driving to failure or replacing when I plan on replacing the timing chain (around 150,000 miles). I am assuming you can get 150k out of a timing chain on a well maintained E320. I have already changed the guide pully and the pulley on the tensioner.
thanks for any comments/thoughts.
