Thermostat

The thermostat is a heat-sensitive valve located in

the coolant outlet connection in the front of the

cylinder head.

When the engine is cold, the thermostat shuts off the

flow of coolant to the radiator, allowing for rapid

engine warm-up. A recirculating bypass allows

coolant to circulate inside the engine whenever the

thermostat shuts off flow to the radiator.

IMPORTANT:

Do not attempt to improve cooling by

removing the thermostat. This will cause the engine

to run below normal working temperatures, resulting

in excessive engine wear.

To install a new thermostat, 1, position it in the recess

of the water outlet connection so that the heat

element (spring end) is in the cylinder head of the

engine.

Fan Belt

NOTE:

Check the condition of the fan belt after every

50 hours of operation. Check fan belt tension after

every 200 hours of operation.

A belt-driven fan located at the front of the engine

draws air through the fins of the radiator to lower the

temperature of the radiator coolant.

When 9-11 kg (20-25 lbs.) of thumb pressure is

applied midway between the belt pulleys, a correctly

tightened belt will deflect 10 mm-15 mm

If the fan belt is slipping, fan efficiency is lowered,

resulting in the engine running too hot. If the belt is

too tight, the life of the alternator bearing will be

shortened. If the fan belt shows signs of cracking or

fraying, install a new one.
