1991 300E water pump

[Gill]

Hi, Was wondering if anyone has any experience replacing the water pump on a 1991 300E . Mine is leaking and needs to be done. I have looked at the job and don't see how to gain access to the lower bolts on the pump. This job may be beyond my ability but I'd like to give it a shot since I'm sure it will cost a bundle at a shop.I was a HVAC tech for quite a few years so I'm no stranger to working with tools and if I could figure how to get this pump out , I know I could put a new one in..I did a search but did not see any info related to this model...
Thanx
William
