my water pump is leaking-help '94 C280
 

I found out today that my water pump on my 1994 c280 is leaking around the seal.

I have a great mechanic, who is honest, and decently priced at $65 an hour.

He says I can do it myself, but I have tried this stuff in the past and gotten into a mess. it seems there are special allen wrenches needed. He says it is not mentally difficult just very tricky to get to.


First question: How hard is replacing the water pump for a decent amature as myself?

2nd question: i am ordering a water pump from fastlane and they want to know what engine from the following 2 options:

-12-034966
-10-004058

Where can I find this engine info? I looked at the plate, the manual and can't determine which engine i have. I know I have the 104.941 engine.

any hellp is always greatly appreciated.

Water pump change outs are not complicated unless there are signs of corrosion on the bolts and between the pump and the block. They tend to be messy though, as you wind up with anti-freeze spilling, and the chances are you do not have a suitable means to collect it as it drains. Based on your self assessment as a mechanic, I would lean towards having your mechanic do the job. Jim

I have come to the same conclusion. Thanks for the input.
