(cooling fan cycling); then increase engine RPM to
3000 RPM. The oil pressure must read 0.6-0.7 kg/
cm

NOTE: If the oil pressure is lower than specified,
check for low oil level or defective oil pump.

NOTE: If the oil pressure is higher than specified,
check for clogged oil passage, clogged oil filter, or
improper installation of the oil filter.
Liquid Cooling System
When filling the cooling system, use a coolant/water
mixture which will satisfy the coldest anticipated weather
conditions of the area in accordance with the coolant
manufacturer’s recommendations.
Checking/Filling
1. Locate the coolant reservoir on the right side behind
the radiator.
2. Remove the cap and fill with the appropriate coolant
until coolant level is between the LOW and FULL
lines. Do not overfill.

3. Install the cap on the reservoir.
While the cooling system is being filled, air pockets may
develop; therefore, run the engine for five minutes after
the initial fill, shut the engine off, and then fill the cool-
ing system to the bottom of the stand pipe in the radiator
neck.
RADIATOR

3. Remove the upper and lower coolant hoses; then
remove the fill hose and air bleed hose.
4. Remove the cap screws securing the radiator to the
frame.
5. Disconnect the fan wiring from the main wiring har-
ness; then remove the radiator/fan assembly and
account for the grommets and collars.
6. Remove the fan/fan shroud assembly from the radia-
tor.
Cleaning and Inspecting
1. Flush the radiator with water to remove any contami-
nants.
2. Inspect the radiator for leaks and damage.
3. Inspect all hoses for cracks and deterioration.
4. Inspect all fasteners and grommets for damage or
wear.
Installing
1. Position the fan/fan shroud assembly on the radiator;
then secure with existing hardware.
CAUTION
After operating the ATV for the initial 5-10 minutes, stop
the engine, allow the engine to cool down, and check
the coolant level. Add coolant as necessary.
