A. Locate and remove the fasteners that secure
the factory transmission cooler to the front
cross-member. Push the cooler up and tem-
porarily secure out of the way. (See Fig. 2-a)
B. Remove the 10mm headed fastener that
secures the plastic wire loom to the front of
the oil pan. (See Fig. 2-b)
C. Mark the hole location as shown on the front
of the pan. Center punch the hole location to
be drilled. (See Fig. 2-c)
D. Drill an 1/8” pilot hole at the previously
marked location. Locate the oil drain assem-
bly (4GN130-036). Use the supplied 9/16”
cutter to enlarge the pilot hole, making sure
to break through easily. Do not stop the drill
motor until the cutter has been extracted so
that the cutout does not fall into the pan. It
may help to pack the cutting tool with grease
to help prevent any stray chips from entering
the oil pan.
E. Thread the hole with a 3/8” NPT tap to
approximately 1/2" deep or until the fitting can
be started. Pack the flutes of the tap with
grease to minimize the amount of debris that
gets into the engine. Access is restricted so
inserting the tap in a socket and then using a
ratchet to rotate it is helpful.
F. Thoroughly clean the threaded area and the
interior of the engine. Apply a small amount
of silicone sealer to the new threads. Apply
more sealer to the 3/8” NPT MALE X .5
FEMAL INVERTED FLARE hose fitting and
secure in the hole. Make sure a seal is
formed all around the fitting. (See Fig. 2-d)
G. Loosely install the TUBE NUT ASSEMBLY
into the previously install fitting. The super-
charger oil drain hose connection will be
made in a later step. Leave the transmission
cooler and wire loom loose until then. (See
Fig. 2-d)
H. Drain the engine oil and change the filter.

2. OIL DRAIN INSTALLATION (ENGINE OIL-FED KITS ONLY. APPLICA-
TIONS WITH V3 SUPERCHARGERS SKIP AHEAD TO STEP 4)
NOTE: To provide an oil drain for the supercharger,
it is necessary to make a hole in the oil pan.
NOTE: When tapping the hole be careful
not to bottom out the tap. If the tap
does bottom before the thread is
large enough you will need to trim
the end of the tap to facilitate a deep
enough thread cut.
