1. Hose

2. Clamp

3. Water outlet socket

Remove:

– water outlet

– socket screws

– gasket thermostat.

To check thermostat, put in water and heat water.

Thermostat should start to open when water tem-

perature reaches the following degree. It will be

almost fully open at 50°C(122°F).

ENGINE TEMPERATURE

42°C(108°F)

Thermostat is a double action type.

– Its function is to give faster warm up of the en-

gine by controlling a circuit; water pump — en-

gine — coolant tank. This is done by bypassing

the radiator circuit.

A16C02A

TYPICAL — CLOSED THERMOSTAT, COLD ENGINE

1. To reservoir

2. From cylinders

– When the liquid is warmed enough, the ther-

mostat opens progressively the circuit, water

pump — engine — radiators — coolant tank

to keep the liquid at the desired temperature.

(See the diagram of the exploded view).

A16C03A

TYPICAL — OPEN THERMOSTAT, WARM ENGINE

1. To radiators

2. From cylinders

These 2 functions have the advantage of prevent-

ing a massive entry of cold water into the engine.
