E. COOLING SYSTEM
a . Checking Adjusting
(A) Fan belt
1. Measure the deflection, depressing the belt half-
way between the fan drive pulley and the alternator
pulley at 98 N (10 kgf, 22 lbs) of force.
2. If the deflection is not between the factory specifica-
tions, loosen the bolts and nuts, and relocate the
alternator to adjust.
3. If the belt is damaged or worn (See figure), replace
the belt.

(B) Radiator water tightness
1. Fill radiator with water to the specified amount and
warm up the engine.
2. Set a radiator tester and raise the water pressure to
the specified pressure.
3. Check the radiator for water leaks.
4. For water leak from the pin hole, repair with a radia-
tor cement, and for other leaks, replace the radiator.

(C)Radiator cap tightness
1. Set a radiator tester on the radiator cap.
2. Apply 88 kPa (0.9 kgf/cm², 13 psi) of pressure and
measure the pressure for 10 seconds.
3. If the pressure falls below 59 kPa (0.6 kgf/cm², 9 psi),
replace the radiator cap.
