COOLING SYSTEM
Inspection and Adjustment
Fan Belt Inspection
(1) Check the belt for contamination with oil, grease and
dust. Replace the belt if required. When the
contamination is slight, remove it clean with rag or
wiping paper. Do not use gasoline, oil or any other
solvent to clean the belt.
(2) During engine overhaul or belt tension adjustment,
closely check the belt for condition. Replace the belt
with a new one if it has any sort of damage.
Fan Belt Tension
Apply a force of 98 N (10 kgf) [22 lbf] perpendicularly to
the belt at a point midway between the fan pulley and
tension pulley. Adjust the tension so that belt deflection
becomes between 11 to 13 mm (0.43 to 0.51 in.).
Connecting Radiator Hoses
When connecting the hoses to the radiator, fit their ends
fully on the fittings and secure them with clamps. Tighten
the clamp bolts to the torques indicated below. Make sure
that each hose is correctly connected and prevented from
disconnection by the flare of the fitting.
