Deflection of between A=7÷9 mm
(0.28÷0.35 in) when the belt is
pressed in the middle of the span.
(1.) Stop the engine and remove the key.
(2.) Apply moderate thumb pressure to belt between pulleys.
(3.) If tension is incorrect, loosen the alternator mounting bolts
and, using a lever placed between the alternator and the
engine block, pull the alternator out until the deflection of the
belt falls within acceptable limits.
(4.) Replace fan belt if it is damaged.
C. Coolant Level Check
The coolant level must be between “MAX COLD” and “MIN”
marks on the reserve tank depending on the temperature of the
engine. Check and ensure that level is correct.
CAUTION
WHEN REMOVING THE RADIATOR FILLER CAP, WHILE THE
ENGINE IS STILL HOT, COVER THE CAP WITH CLOTH, THEN
TURN IT SLOWLY TO GRADUALLY RELEASE THE INTERNAL
STEAM PRESSURE. THIS WILL PREVENT ANYONE FROM
BEING SCALDED BY HOT STEAM SPURTING OUT FROM
THE FILLER NECK.
Add coolant mixed to the correct ratio: 50/50 % ethylene
glycol/water.
