water leak on 300e - water pump or head gasket?

Do you smell any oil in the radiator fluid? If so, it's probably the head gasket.

Chris, remove the undercover from the car, if the water leaks down on the driver side than it's the water pump. I don't see where headgasket would do this, unless there is something you haven't told us ?. Anyway, I've never seen the headgaskets on these cars leak water. Martin Autobahn Auto

LOL,Wow there is some expert advice, shouldn't he smell the oil too for radiator fluid?.

Yep, it's coming from the driver's side alright, so looks like it's the water pump. I'll pick up the O rings & short hose tonight & R & R the water pump over the weekend.

Thanks to all for your insights

Pick up a water pump also.... you will probably need it. :-)

When my pump went it was also leaking in the same manner you described. I did have to replace the whole pump and it was not easy.

If it is an inline six cylinder:

I will recommend that you loosen and move the power steering pump out of the way. Also, I needed 2 1/4 inch socket swivele and a long and short extension for removing the bottom back bolt. I also had to bend a wrench up to reach around and remove the back top bolt. It looks like it is the easiest part to get to but it is really a pain (or at least it was for me)
