2. If the radiator is provided with a recovery tank, check
the coolant level of the recovery tank. When it is
between the "FULL" and "LOW" marks, the coolant

3. When the coolant level drops due to evaporation, add
water only up to the full level.
4. Check to see that two drain cocks; one is at the
crankcase side and the other is at the lower part of the
radiator as figures below.

caution and securely retighten the cap.
