Coolant - Refill
1. Tighten the coolant drain cocks and plugs.
2. Remove the radiator filler cap, and pour in undilut-
ed LLC.
Note: Determine the amounts of LLC and water to be
added by using the LLC concentration chart.
For the coolant, refer to "COOLANT" (6-1). For
the coolant capacity, refer to "MAIN SPECIFICA-
TIONS" (12-1).
3. Pour in water (soft water with minimal impurities,
such as tap water) slowly to "FULL" level line.
4. Check the radiator and other parts for coolant leak-
age. If any coolant leakage is found, repair it.
5. When coolant reaches "FULL" level line, close the
radiator filler cap securely.
6. Run the engine with starter for approx. 10 seconds
while pulling the stop lever.
Stop the operation for 1 minute, then, repeat the
operation two or three times to bleed the cooling
system.
7. Check the coolant level in the radiator.
If the engine is equipped with a reserve tank, fill the
reserve tank with coolant to "FULL" level line as
well.
