1.2.4 COOLING SYSTEM
1.2.4 COOLING SYSTEM (1) Checking cooling liquid
Check the cooling liquid level in the reserve tank.
If the level is below the MIN mark, add cooling liquid of 30% concentration (50 % in coldweather regions) to bring level:
Up to the MAX mark when the engine is warm. 2/3 of the capacity when the engine is cold.
(2) Changing cooling liquid
Shut off the engine and wait fore more than 30 minutes.
Remove the radiator cap and loosen the drain cock at the radiator side.
Loosen the drain cock at the engine side to drain off the cooling liquid.
Tighten the drain cocks at both the radiator and the engine sides.
Add cooling liquid of 30% concentration (50% in cold-weather regions) into the radiator. The rate of addition should be less than 2 L/min (0.5 U.S. gal/min).
After adding cooling liquid, start the engine and let it run at idle rpm for a couple of minutes and check the cooling liquid level. If the level is low, add cooling liquid of the same concentration used in step , as required.
Tighten the radiator cap securely. Add cooling liquid to bring level up to 2/3 of the capacity. Fig. 1.12 Reserve Tank

(3) Adjusting fan belt tension
① Loosen the generator fitting bolts C and C . ② Move the generator away from the engine to adjust the belt tension, so that the fan belt has a deflection of 10 mm (0.4 in) at B on the span when pressed by a finger pressure of about 98N {10 kgf (22.1 lbs)}. ③ Tighten the fitting bolts B and then A.
