(3) Use a new gasket and connect the drain line.
Tighten the drain line connection bolts to 24 N»m (18
ft. lbs.) torque.
(4) New turbocharger must be pre-lubricated with
clean engine lubricating oil before start up. Pour
50-60 cc (2-3 ounces) of oil into supply fitting.
WARNING: DO NOT USE YOUR FINGER TO TURN
THE TURBINE WHEEL.
(5) Rotate the turbine wheel to allow oil to enter
the turbocharger.
(6) Install the oil supply line. Tighten the oil sup-
ply line fitting nut to 15 N # m (11 ft. lbs.) torque.
(7) Position the intercooler inlet duct to the turbo-
charger. With the clamp in position, tighten the
clamp nut to 8 N«m (72 in. lbs.) torque.
(8) Position the air intake pipe and the exhaust
pipe onto the turbocharger. Tighten the clamps to 8
N*m (72 in. lbs.) torque.
(9) Operate the engine and check for leaks.
INTERCOOLER
Intake air is drawn through the air cleaner and
into the turbocharger compressor housing. Pressur-
ized air from the turbocharger then flows forward
through the intercooler located in front of the radia-
tor. From the intercooler the air flows back into the
intake manifold.
The intercooler is a heat exchanger that uses air
flow to dissipate heat from the intake air. As the tur-
bocharger increases air pressure, the air temperature
increases. Lowering the intake air temperature in-
creases engine efficiency and power.
REMOVAL
WARNING: IF THE ENGINE WAS JUST TURNED
OFF, THE INTAKE AND OUTLET DUCTS MAY BE
HOT.
(1) Remove the grille (see Group 23, Body for the
proper procedure).
(2) Remove the front support bracket (Fig. 29).
(3) If the vehicle is equipped with air conditioning,
remove the condenser as follows:
(a) Discharge the air conditioning system (see
Group 24, Heating and Air Conditioning for the
proper procedures).
(b) Remove the bolt from the sealing plate (Fig.
29).
(c) Remove the nuts holding the condenser to the
intercooler (Fig. 29). Lift the condenser and sealing
plate assembly away from the intercooler.

(4) Remove the inlet and outlet ducts from the in-
tercooler (Fig. 30).
(5) Remove the intercooler bolts (Fig. 29). Pivot the
intercooler forward and up to remove.
INSTALLATION
(1) Position the intercooler (Fig. 29). Install the
bolts and tighten to 2 N«m (17 in. lbs.) torque.
