4. 10 ENGINE COOLING SYSTEM
The engine cooling system fluid is a 50 / 50 mixture of
ethylene glycol and water.
To maintain the fluid level, add coolant to the overflow
reservoir (Fig. 4.10A). The overflow reservoir should be
checked daily when the engine is cold. Keep the coolant
level to the line marked on the reservoir.
To drain the cooling system, turn the radiator petcock
(Fig. 4.10B) in to open. Release the radiator cap. Remove
the lower coolant hose from the engine to drain the coolant
from the engine block.
Drain, flush and replenish the cooling system flush every
two (2) years or every 1000 operating hours, which ever
comes first.
WARNING
To avoid personal injury:
DO NOT remove the
radiator cap when the
engine is hot.
