Hi and thanks for using 2CarPros. Com.
I agree with you. Gaskets, o-rings need to be installed on clean and dry surfaces unless otherwise recommended.
First, I suggest getting a new o-ring from a dealer. Often times the aftermarket ones are not of the same quality. Next, do not use sand paper to clean the area. Also, when you reinstall the pump, make sure it is aligned prior to install. If you turn it to make bolt holes align, the o-ring can be damaged.
Here are the directions: They show a sequence for removing bolts. When tightening them to 18 ft/lbs, follow the reverse order of removal. The attached pictures correlate with these directions. Make sure to lube the o-ring with coolant as recommended at the end of the directions.
Remove the bolts in the sequence shown, and the water pump. See pic
Wipe the water pump mounting surface with a soft cloth if necessary.
CAUTION: Do not rotate the water pump housing once installed in the engine. Damage to the O-ring seal can occur, causing the water pump to leak.
NOTE: Install a new O-ring seal and lubricate with Motorcraft Premium Engine Coolant E2FZ-19549-AA, FSFZ-19549-CC in Oregon, CXC-10 in Canada or equivalent meeting Ford specification ESE-M97B44-A (green color) or Motorcraft Premium Gold Engine Coolant VC-7-A meeting Ford specification WSS-M97B51-A1 (yellow color). Use the same coolant that was drained from the engine.
To install, reverse the removal procedure.
Let me know if this helps.
