104. Lubricate the 15/64” bit supplied in Bag #4 with
a small amount of engine oil, then drill into the guide
hole with a bushing until the tape mark on the bit meets
the guide. Loosen the bolt and blow out any chips with
compressed air then turn the guide until the ream hole
lines up with the one just drilled in the crank and balancer.
Use the back side of the ream tool to verify that the holes
line up then tighten the bolt and use the .2500” reamer to
ream the hole.
105. Use compressed air to clear out any metal shards in
the hole. Apply Loctite 609 retaining compound or
equivalent to the supplied crank pin then tap it into the
drilled hole until it is flush.
106. Install the supplied GM crank bolt into the crank and
torque it to 37 ft-lbs, then rotate it an additional 140°
NOTE: You may refer to the Oil COOLER Guide on Pg.9 for
identification and placement of the following components.
107. Remove the wire harness holding clamp from the gap
between the driver side motor mount and the block.
108. Remove the e-clips securing the stock oil lines to the
distribution block located directly above the oil filter then
pull out discard the stock oil lines.
109. Use a 10mm socket to remove the distribution block
from the side of the oil pan and discard it.
110. Use a 10mm socket to remove the two center oil pan
rail bolts.
111. Place a wide drain pan below the driver side of the
crossmember. Even if the coolant has been previously
drained, there will still be a significant amount remaining
in the block.
112. Use a 17mm Allen socket and a 1/2” breaker bar to
remove the threaded freeze plug located on the driver side
of the engine block near the front of the engine.
113. Install the supplied threaded fitting into the hole
previously occupied by the freeze plug.
114. Use a 13mm wrench to loosen the knock sensor then
re-clock it so that it will clear the new oil cooler. Tighten
the sensor back down once it is correctly positioned.
115. Install the male nipple fitting into the short rubber
hose and secure it with a spring clamp. Install the supplied
convolute over the hose then route it between the driver
side engine mount and the block and push the nipple into
the fitting in the block.
116. Attach the short section of the long molded hose to
the supplied hard line and secure it with a worm clamp.
117. Lower the newly assembled water line down near the
upper radiator hose and route it so that it will pass in front
of the steering rack and between the engine mount and the
block so that the fitting is near the oil filter.
118. Attach the bracket to the cooler using the supplied
bolts. Apply a dab of lube to the O-ring on the 90° swivel
fitting and insert it into the lower provision of the cooler.
