Reassembly
5. Connect the wire leads to the temperature
warning switch, audible alarm, and/or Oil
Sentry™ switch as equipped.
If the thermostat and thermostat housing were
removed from the intake manifold, reassemble them
at this time.
6. Make sure the sealing surfaces of housing and
manifold are clean and free of nicks or damage.
7. Install the thermostat into the recess in the
intake manifold, so the larger spring end is
down. Place a new thermostat housing gasket
onto the manifold surface, aligning the screw
holes. Make sure that one of the notches in the
gasket is aligned with the by-pass slot in the
manifold and the thermostat housing. Do not
use a substitute gasket. See Figure 11-60.
Figure 11-60. Installing Thermostat and Gasket.
8. Position the thermostat housing on the gasket
and intake manifold. The notch in manifold,
gasket and thermostat housing must all be
aligned. Install and torque the two hex flange
screws to 9.9 N·m (88 in. lb.). See Figure 11-61.

9. Apply rubber lubricant to the inside end of the
upper radiator hose, and install the hose to the
thermostat housing, if separated for servicing.
Secure with the clamp. Make sure tangs of clamp
point toward the #1 cylinder, away from the fan.
Install Coolant By-pass Hose
from intake manifold through individual
component servicing)
1. If the connector fitting for the by-pass hose was
removed from the manifold, reinstall it at this
time. Apply pipe sealant with Teflon
59241 or equivalent) onto the threads and
tighten, so the fitting faces/points toward the #2
side, long intake manifold screw.
2. Attach the coolant by-pass hose to the fittings in
the water pump and intake manifold. Secure
with the clamps.
