3. OIL DRAIN (2000-2005 MODELS ONLY)
Fig. 3-a
Fig. 3-b
A. Drain the engine oil and change the filter.
B. To provide an oil drain for the supercharger, it
is necessary to make a hole in the pan.
C. Remove (6 screws) the tubular chassis cross-
member located beneath the rear of the
engine.
D. Remove the oil pan bumper that is attached
to the vehicle frame in front of the oil pan.
E.
Remove the two screws that attach the oil
pan to the transmission bellhousing.
F.
Remove the two lower A/C compressor pump
mounting bolts that attach to the oil pan
mounting bracket. Leave the small aluminum
mounting bracket attached to the pan.
G. Remove the remaining oil pan screws around
the perimeter of the pan and carefully remove
the pan.
H. Locate and mark the drain hole location on
the oil pan as per Figs. 3-a, 3-b. The hole
location is between the two fins as shown,
and down from the sealing surface of the pan
1.25". Grind down the fins on the oil pan as
shown.
I.
Using the supplied 9/16" rota-broach cutter
and arbor, carefully machine a through hole
into the pan in the location specified.
J.
From the outside of the pan, tap the hole with
a 3/8" NPT tap approximately 1/4" deep.
Pack the flutes of the tap with heavy grease
to hold the chips. Thoroughly clean the
threads and hole with acetone or lacquer
thinner.
K. Using a small amount of silicone sealer,
install the 3/8"NPT x 1.5" hex nipple into the
oil pan. Thread the supplied 3/8"NPT female
x -8 flare fitting onto the hex nipple.
Temporarily cap the fitting until the drain hose
is connected in Step 12.
L.
Thoroughly clean the mating surface of the oil
pan flange and the bottom of the engine
block. The surfaces must be free from oil so
that a proper seal can be achieved when the
pan is reinstalled.
M. Apply a small amount of Hondabond sealer
(available at the local Honda dealership) to
the oil pan mating flange.
N. Reattach the pan to the engine. Reinstall all
of the factory hardware.
O. Reinstall the two A/C compressor screws,
factory oil pan bumper and chassis cross-
member.
P.
Re-fill engine with factory specified weight oil.
Vortech recommends the use of synthetic oil.
