Liquid Cooling System

NOTE: Debris in the engine com-
partment or packed between the cool-
ing fins of the radiator can reduce
cooling capability. Using a garden
hose, wash the radiator to remove
any debris preventing air flow.
The cooling system capacity can be found
in the specification chart. The cooling sys-
tem should be inspected daily for leakage
and damage. If leakage or damage is
detected, take the vehicle to an authorized
Cushman dealer for service. Also, the cool-
ant level should be checked periodically.

NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine temperature. Decreasing
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
When filling the cooling system, use a
coolant/water mixture of 60/40 or a cool-
ant/water mixture which will satisfy the
coldest anticipated weather conditions of
the area in accordance with the coolant
manufacturer’s recommendations.
Always maintain the coolant level at the
cold fill line of the coolant reservoir.
Checking Coolant
1. Lift the hood by turning the 1/4-turn
fasteners located at the rear of the
hood. Remove the hood by sliding it
toward the rear of the vehicle and out
of the slots in the grill.

2. Inspect the coolant level cold. The
level shouldn’t be lower than the cold
full line. When it’s at operating tem-
perature, the coolant level may be
above the cold full line.
MOD043

NOTE: If you cannot see any cool-
ant in the reservoir, inspect the
cooling system for leaks. If no leaks
are present, add coolant using the
bleed procedure below. If a coolant
leak is suspected, schedule ser-
vice with an Authorized Dealer.
Bleeding Cooling
System
While the cooling system is being filled,
air pockets may develop; therefore, make
sure the cooling system is properly bled,
with no trapped air in the system.
1. Slowly remove the plug from the top
of the thermostat housing on the right
side of the engine allowing trapped
air to escape.
CAUTION
Cushman does not recommend using
a pressure washer to clean the radia-
tor core. The pressure may bend or
flatten the fins causing restricted air
flow, and electrical components on
the radiator could be damaged. Use
only a garden hose with spray nozzle
at normal tap pressure.
CAUTION
Continued operation of the vehicle
with high engine temperature may
result in engine damage or premature
wear.
! WARNING
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
