Figure 1 – Prepping The Block

Disconnect battery; remove all existing accessory drive brackets and components
from motor.

Remove water pump and housing, scrape away any existing gasket material with
a gasket scraper and dress surface with a Scotch Brite® pad.

Clean and prep threads on engine block at water pump, use a 3/8-16 thread
chaser if necessary. Thread chasers are available at your local auto parts store or
tool dealer and are different from a thread cutting tool.

Apply RTV sealer to one end of the 3/8-16 x 3” threaded stud and thread stud
into the driver side top water pump mount hole. Next apply RTV sealer to one
end of the 3/8-16 x 4-1/4” stud and thread into the lower driver side mount hole
and tighten. Apply RTV sealer to one end of the remaining 3/8-16 x 3-1/2” stud
and thread into the bottom passenger side mount hole and tighten. The studs
can easily be tightened by threading two 3/8-16 zinc coated nuts onto the stud
and tighten them against each other to act as a drive nut, see example. Apply
anti-seize to the exposed threads of the studs at this time. Check installed height
of studs by sliding water pump housing on to the studs. There should be 1/2” of
exposed threads on each stud, readjust as necessary.
