C: INSTALLATION
1) Install flywheel.
2) Install ST, and tighten the flywheel attaching bolts to the
specified torque.
ST 498497100 CRANKSHAFT STOPPER
Tightening torque:
72±3 N⋅m (7.3±0.3 kg-m, 52.8±2.2 ft-lb)
NOTE:
Tighten flywheel installing bolts gradually. Each bolt should
be tightened to the specified torque in a crisscross fashion.
G2M0253
3) Insert ST into the clutch disc and install them on the
flywheel by inserting the ST end into the pilot bearing.
ST 499747100 CLUTCH DISC GUIDE
G2M0254
4) Install clutch cover on flywheel and tighten bolts to the
specified torque.
NOTE:
When installing the clutch cover on the flywheel, position
the clutch cover so that there is a gap of 120°or more
between“0”marks on the flywheel and clutch cover. (“0”
marks indicate the directions of residual unbalance.)
Note the front and rear of the clutch disc when installing.
Tighten clutch cover installing bolts gradually. Each bolt
should be tightened to the specified torque in a crisscross
fashion.
Tightening torque:
15.7±1.5 N⋅m (1.6±0.15 kg-m, 11.6±1.1 ft-lb)
5) Remove ST.

3. Thermostat
A: REMOVAL AND INSTALLATION
1) Drain engine coolant.
Set container under the vehicle, and remove drain cock
from radiator.
2) Disconnect radiator outlet hose from thermostat cover.
3) Remove thermostat cover and gasket, and pull out the
thermostat.
G2M0227
4) Install the thermostat in the intake manifold, and install
the thermostat cover together with a gasket.
CAUTION:
When reinstalling the thermostat, use a new gasket.
The thermostat must be installed with the jiggle pin
upward.
In this time, set the jiggle pin of thermostat for front
side.
G2M0215
B: INSPECTION
Replace the thermostat if the valve does not close com-
pletely at an ambient temperature or if the following test
shows unsatisfactory results.
Immerse the thermostat and a thermometer in water. Raise
water temperature gradually, and measure the temperature
and valve lift when the valve begins to open and when the
valve is fully opened. During the test, agitate the water for
even temperature distribution. The measurement should
be to the specification.
Starts to open:
76.0—80.0°C (169—176°F)
Fully opens:
91°C (196°F)
