MAINTENANCE
Radiator
Check Daily: Always check the level of the coolant in the
radiator before starting the engine. Remove the radiator
cap and verify that the coolant reaches top of radiator coils.
1. DO NOT remove the radiator cap while the coolant is
hot. The possibility exists of severe burns or scalding
from the coolant gushing out. Let the coolant cool
before removing radiator cap.
2. Check coolant in the reserve tank daily (Figure 34).
Make sure the level is between the FULL (H) and LOW
(L) markings. Fill reserve tank with a mixture of 50/50
antifreeze/water.
