Cooling System

Never remove radiator cap or overflow reservoir

cap when engine is hot. Pressurized hot steam
and water may be released, causing serious burns
or possible blindness. Figure 4-11

Engine cooling is accomplished with circulated water and
Ethylene Glycol mixture. The radiator is equipped with a pres-
sure cap and recovery tank. A 50-50 mixture is recommended
for all season operation. This mixture provides freeze protec-
tion to -32 degrees F (-35 degrees C). Should temperatures
fall below this level, additional Ethylene Glycol must be
IT
added to the mixture.
Visually inspect the system daily prior to operating the
mower. Check coolant level in the recovery tank located to
the left rear of the engine (Figure 4-11). When the engine is
cold the coolant should be up to the cold mark on the recov-
ery tank. When the engine is hot the coolant should be up to
NL the hot mark on the recovery tank. When adding coolant, pre-
mix the solution before adding it to the recovery tank. It is
not necessary to remove radiator cap for adding small
amounts of coolant to the system.

General Engine Maintenance

Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine Owner's
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
engine manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
Belts
Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
Slight raveling of belt covering does not indicate failure,
trim ravelings with a sharp knife.
If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose
steering control while operating the machine, place
the steering control levers in the park brake position
immediately. Inspect the machine and involve your
Hustler Dealer to resolve the problem before con-
®
tinuing to operate.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the
case, otherwise the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or dam-
age the fibers of the belt covering.
