I have a coolant leak coming from the block on my 240D. I checked to make sure it wasn't coming down from the T-stat housing, but it seems to be coming from where the t-stat sort of mounts to the block - and where the fan mounts to the block as well. Is there a gasket there? I'm going to replace my thermostat in the near future, but it seems to be operating correctly since the car warms up and stays at the proper operating temperature.

get a small mirror and look at the underside of the waterpump, you will see a small hole (apox. 3/16") if you see coolant or evidence of coolant leaking from here you should replace your pump. if memory serves me i think there is an o-ring around the water pump housing.....

Okay, yeah, that's the water pump and there is coolant coming from a small hole on the pump. Is this going to be a ***** of a job?

It's incredibly quick and easy.

take your time, i cut a piece of cardboard to put against the radiator to prevent damage, than unbolt the fan and lay it against the radiator or remove it for more room, but leave thr cardboard against the radiator to protect it, use some PB blaster or any other rust penetrating fluid on the bolts, once bolts are out you may need to gently tap the pump(with small hammer) to get it out...be sure to get a new GASKET (not o-ring) as originally thought, with the new pump..

I can't seem to find the bolts for the fan. Are they different than on the 300D engine?
