Water pump for 66 230s M180
What should be used to seal the bolts that attach the water pump to the aluminum housing?
When I removed the pump and the housing it looked like there was some dried "gunk" on the threads. The bolts run all the way through the outer 1/2 of the housing, the holes are exposed inside. There must be some thread sealant required or there could be some leakage around the 5 bolts. (I have the 2 gaskets already)
I checked the EPC and expected to find the small copper crush washers. They aren't listed.
My Service Manual for Passenger Cars starting 1959 (SM1202) only covers the 300SE which looks much different. My Glenns manual skips the subject also.
Also - where should the notch on the water pump be located (i.e. 3:00, 6:00, etc). Does it even matter?
Search first, ask second!
