Hi DaveK,

I think you have the same problem that I have with my 92 190e 2.6. I have the same leak in exactly the same location. I am about to replace my waterpump tomorrow. You can read my thread http://www.peachparts.com/shopforum/showthread.php?threadid=29568

Also here is some information on removing the waterpump from Benzmac http://www.peachparts.com/shopforum/showthread.php?threadid=6980&highlight=waterpump

I hope this helps. Good luck!

Walter
