check the radiator. Steam can spurt out
during engine operation if the cap is loose.
• Always check the level of the engine coolant
by observing the reserve tank.

Periodic Maintenance Procedures
CAUTION
Coolant Hazard!
• Failure to comply may result in minor or
moderate injury.
NOTICE
• Always be environmentally
responsible.
• Follow the guidelines of the EPA or other
governmental agencies for the proper disposal of
hazardous materials such as engine oil, diesel
fuel and engine coolant. Consult the local
authorities or reclamation facility.
• Never dispose of hazardous materials
irresponsibly by dumping them into a sewer, on
the ground, or into ground water or waterways.
• Failure to follow these procedures may seriously
harm the environment.
Engine coolant contaminated with rust or scale
reduces the cooling effect. Even when extended life
engine coolant is properly mixed, the engine
coolant gets contaminated as its ingredients
deteriorate. Drain, flush and refill the cooling
system with new coolant every 1000 hours or once
a year, whichever comes first.
1. Allow engine and coolant to cool.
2. Remove the radiator cap (Figure 5-15, (1)).
