Default 6.9 Water Pump Removal

There's been a fair bit of discussion on the M100 site regarding removal and replacement of the above pumps.

Some contributors maintain that it is necessary to remove the crankshaft pulley in order to remove the pump. Others advocate the removal of both pump and the housing it is attached to as one unit. I have found, without fail and each and every time, the pump can be removed without having to touch the other two components. Sure, it is a VERY close and tight fit as the impeller flange is almost an interference fit in the housing, but it can be done. The most delicate part involves the JUDICIOUS use of force to actually break the gasket seal to free up the pump.One needs to be very careful. Regards Styria

What would constitute judicious amounts of force in this instance?

Hi S-Class, depending on the type of sealant used, the water pumps can be very stubborn to respond to removal attempts. Looking at the car from the front, one can only use the spout to which the bottom hose is attached to as a means of leverage to break the seal and force it away from the pump housing. I normally use a wedge type of lever to gently put pressure on that spout, and keep on tapping the pump itseld with a wooden or plastic mallett. You only need a slight bit of movement which then enables one to spray Inox or even WD 40, or even oil for that matter, in between the pump body and the water pump housing. At the same time, keep on applying 'gentle' leverage with your wedge type lever. Eventually, it will let go. Regards, Styria
