Hello, Thanks for the alternator cleaning ideas. All belt-driven pumps are off the mighty 78 NYB. A 1978 chassis manual I found on Ebay specifies removing the fan, water pump and water pump housing as a unit AFTER removing the vibration damper from the end of the crankshaft. If anyone has actually done this repair, could you comment as to how this worked for you? Also, should the water pump housing be hard as all get-out to pull off once the bolts are removed? (Mine is). thanks Bruce s 69 coupe 71 Imperial 78 NYB __________________________________ Do you Yahoo!? Yahoo! Mail - More reliable, more storage, less spam http://mail.yahoo.com
