So, did you replace your water pump? Did it really take 4 days?! I susect my waterpump (85 380SL) has also gone bad. Curious though. On most american cars I've had, when a water pump goes bad, the fan wiggles a bit. The fan on my mercedes is tight with no wiggle.

I've replaced water pumps before (Ford and Chevy). Is it still the opinion of the forum that it will take 4 days?
