INSTALLATION
ENGINE OIL COOLER
(1) Install radiator assembly. Tighten lines to radi-
ator fittings to 18 N·m (160 in. lbs.) (Fig. 40).
COOLER LINES
(1) Position cooler lines and connect lines to radia-
tor fittings. Tighten lines to radiator fittings to 18
N·m (160 in. lbs.) (Fig. 40).
(2) Connect lines to pressure control valve and oil
pan fitting. Tighten lines to 30 N·m (260 in. lbs.)
(Fig. 40).
(3) Connect lines to support retainer and isolator.
PRESSURE CONTROL VALVE
(1) For installation of a NEW control valve:
(a) Install fitting into block. Tighten fitting to 30
N·m (260 in. lbs.).
(b) Position control valve to fitting. Push line
into fitting until it locks in place. Ensure proper
connection is made by pulling in-and-out on valve.
(2) For installation of original control valve:
(a) Install pressure control valve to engine block.
Tighten fitting to 30 N·m (260 in. lbs.) (Fig. 40).
(3) Connect oil cooler supply line. Tighten to 30
N·m (260 in. lbs.).
(4) Connect oil pressure switch connector.
ENGINE BLOCK HEATER
REMOVAL
(1) Raise vehicle on hoist.
(2) Detach power cord plug from heater (Fig. 41).
(3) Remove block heater attaching screw located
below heater terminals.
(4) Remove block heater from cylinder block.
INSTALLATION
(1) Thoroughly clean cylinder block heater cavity.
(2) Insert heater assembly into block such that
mounting hole is located below heater terminals.
(3) Install mounting screw and tighten to 12 N·m
(105 in. lb.).
(4) Attach power cord to heater.
CAUTION: To prevent damage, the power cord
must be secured in its retainer clips, and not posi-
tioned so it could contact linkages or exhaust man-
ifolds.
(5) Lower vehicle.
ACCESSORY DRIVE BELTS—2.7L
AIR CONDITIONING BELT
NOTE: The A/C drive belt self tensioner is NOT a
dynamic tensioner. After tensioner adjustment
bracket bolts are tightened, the torsion spring is no
longer responsible for tensioning the A/C belt. The
torsion spring is only used for initial belt tensioning
only.
REMOVAL
(1) Remove generator/power steering belt. Refer to
procedure in this section.
(2) Loosen BUT DO NOT REMOVE tensioner
locking bolt and pivot bolt (Fig. 42).
(3) Insert 1/2” drive breaker bar into square open-
ing on belt tensioner. Rotate tensioner counterclock-
wise until belt can be removed from pulleys (Fig. 42).
(4) Slowly rotate tensioner clockwise to relieve
spring load.
INSTALLATION—NEW BELT
WARNING: DO NOT REMOVE A/C BELT TEN-
SIONER LOCKING BOLT WITHOUT FIRST HOLDING
THE TENSIONER WITH A 1/2” DRIVE BREAKER
BAR, AS PERSONAL INJURY COULD RESULT.
NOTE: Verify that torsion spring position is in the
new belt position before installing a NEW belt (Fig.
43). If torsion spring is not in the new belt position,
follow steps1–7tochange the tensioner spring
from the USED belt position to the NEW belt posi-
tion.
(1) Insert a 1/2” drive breaker bar into the square
opening on the tensioner. Hold counterclockwise pres-
sure on tensioner while removing the locking bolt
(Fig. 42).
