4.3.4. V-belt check and adjustment

(1) Visual check

Check the belt for cracks, oil, overheating and wear.

(2) Tension check

By the finger-pressure, the belt is

pressed by 10 ~ 15mm between the

water pump pulley and the alternator

pulley in normal condition.

For the adjustment of the tension,

loosen the adjusting bolts which support

the alternator, adjust the tension and

tighten the bolts again.

(3) V-belt change

Change the belt if necessary after every

2,000 hours of operation.

If, in the case of a multiple belt drive,

wear or differing tensions are found,

always replace the complete set of the

belts.

Note : Always apply to DAEWOO genuine parts every replacement.

4.3.5. Thermostat check

The thermostat maintains a constant

temperature of coolant (71 ~ 85 °C) and

improves thermal efficiency of the engine

by preventing heat loss.

Namely, when the temperature of coolant is

lower than 85 °C, the thermostat valve is

closed to make the coolant bypass to

directly enter the water pump. When the

coolant temperature rises to open wide the

thermostat valve, the bypass circuit is

closed and the water passage to the heat

exchanger is opened so that the coolant is

forced to flow into the heat exchanger.
