ENGINE COOLING
CHECK
Check the pad of the thermostat for cracks.
Check the functioning of the thermostat as follows:
• Pass a piece of string through the flange as indicated in the figure.
• Immerse the thermostat in a heat-resistant glass of water as indi-
cated in the figure. Check that the thermostat floats and then heat
the water with a burner. Observe the increase in the temperature
of the thermometer.
• Observe the temperature at the moment when the thermostat
opens. The temperature should be as specified by the following
values.
Standard
Thermostat valve opening temperature: 74.5 – 78.5°C.
• Continue to heat the water to increase the temperature.
• When the temperature of the water reaches the temperature speci-
fied, the thermostat valve should lift up at least 7 mm.
Standard
Lifting up of the thermostat valve: more than 7 mm at 90°C.
• If the thermostat does not operate correctly in either of the two
cases (opening temperature and lifting up of the valve), it must be
substituted.
ASSEMBLY
Install the thermostat in the reverse order of removal.
• Grease the rubber seal of the thermostat.
Specified product: AGIP GREASE 30
• The hole for the bleeding of air A on the thermostat must be placed
upwards.
• Make sure that the cooling circuit tubes are placed correctly and
are not squashed or bent.
• After reassembling the thermostat, top up the system with engine
coolant (see page B-20 for further information on topping up).
Torque pressure
Engine coolant drain plug
(M6): 5.5 N.m (0.55 kg-m)
Air bleed bolt
(M8) : 13 N.m (1.3 kg-m)
