CHECK ENGINE COOLANT LEVEL
The engine coolant level and quality should be
checked before each use, when the engine is cool
and off.
1. Remove the radiator pressure cap (A, Figure 18)
to check the fluid level.
2. Coolant level should be 1/2” (13mm) below the
bottom of the filler tube. If coolant level is low, add
coolant until level is 1/2” (13mm) below the bottom
of the filler tube. Proper coolant mix is a 50/50
mixture of ethylene glycol and distilled water. See
engine owners manual for engine coolant
specifications.
3. Check the coolant level in the radiator expansion
tank (Figure 19). If coolant level is low, remove
the cap add coolant until level is at the “FULL” line.
Proper coolant mix is a 50/50 mixture of ethylene
glycol and distilled water. See engine owners
manual for engine coolant specifications.
CHANGE ENGINE COOLANT
See engine owners manual for specific engine coolant
procedures. The drain valve is located at the base of
the right-hand side of the radiator.
CLEAN RADIATOR, SCREEN & OIL
COOLER
Clean the radiator, screen and oil cooler fins before
each use, or as required (depending on conditions) to
allow proper air-flow through radiator and hydraulic oil
cooler.
1. Raise the seat plate.
2. Lift the radiator screen straight up to remove the
screen. Flush the screen with water or blow clean
with air. Flush the radiator core with water or blow
clean with air. See engine owners manual for
proper radiator cleaning procedures.
3. Clean all dirt, grass, and debris from the oil cooler
fins.
4. Reinstall the radiator screen. Make sure the
screen is fully seated in the carrier.
5. Lower the seat plate.
WARNING
PRESSURIZED SYSTEM
Hot coolant can cause serious burns. To open
the cooling system filler cap, stop the engine
and wait until the cooling system components
are cool. Loosen the cooling system pressure
cap slowly in order the relieve the pressure.
