5. OIL DRAIN
A. Un-secure the hard coolant tube mounted to
the cross member directly in front of the oil
pan. Un-secure the power steering line/wiring
bracket located on the bottom lip of the oil
pan. Push these brackets/tubes down to gain
access to the oil drain area. (See Fig 5-a)
B. To provide an oil drain for the supercharger, it
is necessary to make a hole in the oil pan.
Locate and center punch the hole per
Fig 5-b. Drill a 1/8" pilot hole at center loca-
tion.
C. Use the supplied 9/16" roto broach to drill the
hole in the oil pan. Take care to break through
the pan gently and remove the cut out.
D. Pack the flutes of the 3/8NPT tap with
grease. Tap the hole until the fitting can be
started.
E. Thoroughly clean the threaded area. Reach
inside the oil pan and retrieve any stray chips.
Apply a small amount of sealer to the new
threads. Apply more sealer to the supplied
3/8" NPT x 1/2" barb x 90° fitting and secure
in the hole. Make sure the seal is formed all
around the fitting. Install the supplied 90°
elbow pointing to the drivers side and slightly
up. (See Fig 5-c.)
F. Re-secure the hard coolant tube to the lower
cross member.
G. Install the supplied spacers between the
power steering/wiring bracket and the oil pan
mounting lip with the supplied 8mm x 45mm
long hardware.(See Fig 5-a.)
