Cooling System
Maintenance
DANGER
Discharging hot pressurized coolant or
touching hot radiator and surrounding parts
can cause severe burns.
• Do not remove the radiator cap when the
engine is hot. Always allow the engine to
cool at least 15 minutes or until the radiator
cap is cool enough to touch without
burning your hand before removing the
radiator cap.
• Do not touch radiator and surrounding
parts that are hot.
DANGER
The rotating fan and drive belt can cause
personal injury.
• Do not operate the machine without the
covers in place.
• Keep fingers, hands and clothing clear of
rotating fan and drive belt.
• Shut off the engine and remove the ignition
key before performing maintenance.
CAUTION
Swallowing engine coolant can cause
poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.
Checking the Cooling
System
Service Interval: Before each use or daily
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol anti freeze.
Check the level of the coolant in the expansion tank at
the beginning of each day before starting the engine.
The capacity of the cooling system is 7.5 liters (6
quarts).
1. Check the level of the coolant in the expansion
tank (Figure 58). The coolant level should be
between the marks on the side of the tank.
1. Expansion tank
2. If coolant level is low, remove the expansion tank
cap and replenish the system. Do not overfill.
3. Install the expansion tank cap.

Cleaning the Radiator

Service Interval: Before each use or daily
Every 1,500 hours
Every 200 hours
Every 2 years
To prevent the engine from overheating, the radiator
must be kept clean. Normally, check the radiator daily
and, if necessary, clean any debris off these parts.
However, it will be necessary to check and clean
the radiator frequently in extremely dusty and dirty
conditions.
Note:
If the mower deck or engine shuts off due to
overheating, first check the radiator for excessive
buildup of debris.
Clean the radiator as follows:
1. Open the hood.
2. Working from the fan side of the radiator, blow
out debris with low pressure (50 psi) compressed
air (do not use water). Repeat the step from the
front of the radiator and again from the fan side.
3. After the radiator is thoroughly cleaned, clean
out debris that may have collected in the channel
at the radiator base.
4. Close the hood.
