Thermostat

General Information

The thermosatat maintains water temperature in the

engine consistently and prevents heat loss to improve

heat efficiency of the engine.

When the coolant temperature is below the normal

temperature, the thermostat is closed and the coolant is

bypassed and directly flows into the water pump. When

the coolant temperature reaches the normal temperature

or is higher than the temperature, the thermostat is fully

open and the bypass circuit is closed. So the coolant

flows into the radiator.

DV2213099A

Check of the thermostat

1. Check whether the wax pellet and the spring are

damaged or not.

2. Put the water temperature controller into water and

heat the water slowly to check water temperature

controller operation.

3. The water temperature controller is normal in the

following case: it starts to be open at the water

temperature of 82°C and it is fully open at the water

temperature of 97

DV2213100A_E

4. Check if there is any foreign substance in the water

temperature controller.

Note) Clean the inside of the water temperature controller

with an air gun.

5. Check if there are any foreign substance or damage

part inside and outside of the hose.

CAUTION

•

The wax pellet type thermostat shows slower

response to the change of cooling water than the

bellows type thermostat. This happens because

the heat capacity of the wax pellet type water

temperature controller is larger than that of the

bellows type water temperature controller. There-

fore, to prevent rapid increase of engine coolant

temperature, you must first operate the engine at

idle until the engine is fully warmed up. When the

weather is very cold, do not operate the engine

in an overloaded condition or at high speed after

starting the engine.

•

When draining water from the engine cooler or

injecting water to the engine cooler, work slowly

to let the air in the cooler is fully exhausted.

•

When a defect is found in the water temperature

controller, replace it with a new one.
