Figure 1: Prepping The Block
Disconnect battery; remove all existing accessory drive brackets and components from
motor. Remove crankshaft damper and spacer. Remove water pump and timing cover
housing, scrape away any existing gasket material with a gasket scraper and dress surface
with a Scotch Brite® pad. Drop oil pan and repeat surface prep. Clean and prep threads
on engine block, use a 5/16-18 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.
Install Studs In Block
Apply RTV sealer to one end of the four 5/16-18 x 4” threaded studs and thread 1 stud (A)
into the lower passenger side water pump mount hole. Skip the upper water pump hole
and thread the second stud (B) into the upper passenger block mount hole. Follow by
threading stud (C) into the upper driver side block mount hole near the distributor. Thread
the last remaining stud (D) into the upper water pump mount hole on driver side of block.
Apply anti-seize to the exposed threads of the studs at this time. Check installed height of
studs by measuring 3-1/2” from block surface – adjust studs if necessary. Apply anti-seize
to the exposed threads on each stud. The studs can easily be tightened by threading two
5/16-18 zinc coated nuts (supplied) onto the stud and tighten them against each other to
act as a drive nut (discard nuts after use).
