NOTE: Some oil seepage may occur when installing
the oil pressure gauge. Wipe up oil residue with a
cloth.
3. Start the engine and run at 3000 RPM. With the oil
temperature at 60° C (140° F), the oil pressure gauge
must read 1.05-1.2 kg/cm2 (15-17 psi).
NOTE: If the oil pressure is lower than specified,
check for low oil level, defective oil pump, or
restricted oil cooler.
NOTE: If the oil pressure is higher than specified,
check for too heavy engine oil weight (see General
Information), clogged oil passage, clogged oil filter,
or improper installation of the oil filter.
Oil Cooler
REMOVING
NOTE: It is not necessary to drain the engine oil for
this procedure.
1. Remove the input and output hoses from the fittings
on the cooler.
2. Remove the cap screws securing the oil cooler to the
frame. Account for grommets.
3. Remove the oil cooler from the frame.
INSTALLING
1. Place the cooler into position in the frame.
2. Secure the cooler to the frame with the cap screws
and grommets.
3. Install the hoses onto their respective fittings and
secure with the clamps.
Liquid Cooling System
When filling the cooling system, use premixed Arctic Cat
Antifreeze. 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 cooling system to the bottom of the stand pipe in
the radiator neck.
RADIATOR
Removing
1. Drain the coolant at the engine.
2. Remove the front rack (see Steering/Frame/Con-
trols).
3. Remove the front bumper and front fender panel (see
Steering/Frame/Controls).
4. Remove the upper and lower coolant hoses.
5. Remove the cap screws and nuts securing the radia-
tor to the frame.
6. Disconnect the fan wiring from the main wiring har-
ness; then remove the radiator/fan assembly and
account for the grommets and collars.
7. 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.
2. Place the radiator with grommets and collars into
position on the frame; then install the cap screws and
nuts. Tighten securely.
3. Install the upper and lower coolant hoses; then
secure with hose clamps.
CAUTION
Elevate and secure the hoses to avoid oil spillage.
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.
