ZD30DI viscous fan service

[SupRob]

Hi Mike,

When I did mine, I took out the alternater (To get the the thermostate) which loosed the belt, then took the whole waterpump out.

Of course at this time I have no coolant/water in the system.

As far as im aware they are not serviceable, brand new water pump including clutch fan should be no more then $250 pending brand..

Rob,
