PERIODIC MAINTENANCE
CAUTION
• 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 5-16, (1)).
3. Remove the drain plug or open the drain cock
(Figure 5-16, (2)) at the lower portion of the
radiator and drain the engine coolant.
5-36
4. Drain the coolant from the engine block.
• On models not equipped with an oil cooler,
remove the coolant drain plug
(Figure 5-17, (1)) from the engine block.
