Testing Oil Pump
Pressure
NOTE: The engine must be warmed up to the speci-
fied temperature for this test (see Engine/Transmis-
sion - Specifications).
1. Connect the Tachometer to the engine.
2. Disconnect the oil pressure switch connector; then
connect the Oil Pressure Test Kit to the oil pressure
switch port.
DE077B
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 the recommended RPM.
The oil pressure gauge must read as specified (see
Engine/Transmission - Specifications).
NOTE: If oil pressure is lower than specified, check
for an oil leak, damaged oil seal, defective oil pump,
or oil cooler.
NOTE: If oil pressure is higher than specified, check
for too heavy engine oil weight (see General Informa-
tion - Fuel-Oil-Lubricant), clogged oil passage,
clogged oil filter, or improper installation of the oil fil-
ter.
Liquid Cooling System
To check the cooling system, see Periodic Maintenance/
Tune-Up.
DRAINING COOLANT
The cooling system does not have a drain; therefore,
coolant must be removed using the following procedure.
1. Using suitable in-line clamps, close off the lower
radiator hose and the coolant bypass hose next to the
water pump.
DE510A
2. Place a suitable drain pan with a capacity of at least 4
l (4.2 U.S. qt) under the left front of the engine; then
loosen the hose clamp on the coolant bypass hose.
3. Remove the hose and allow coolant to drain into the
drain pan. A funnel or short hose can be used to
direct coolant into the drain pan.
4. Install the coolant bypass hose and tighten the clamp
securely; then remove the in-line clamps.
FILLING COOLANT
1. Elevate the rear of the ATV approximately 30 cm (12
in.) and secure in place using appropriate blocks.
2. Remove the cap from the filler neck (located under
the service access cover) and slowly pour the recom-
mended amount of coolant into the system.
3. Move the ATV outside or to a well-ventilated area
and start the engine allowing it to run for several
minutes; then remove the filler cap and check the
coolant level. Add coolant as required until coolant
is visible within one inch of the top of the filler neck.
4. Install the filler cap on the filler neck and tighten
until the cap contacts the stop.
Radiator
REMOVING
1. Drain the coolant at the engine.
2. Remove the front rack (see Steering/Frame).
3. Remove the front bumper and front fender panel (see
Steering/Frame).
4. Remove the upper and lower coolant hoses.
CAUTION
Failure to elevate the rear of the ATV may result in air
being trapped in the cooling system causing severe
engine damage due to overheating.
! WARNING
Do not over-tighten coolant filler cap or excess pres-
sure will build up in the cooling system causing cooling
system damage and possible bodily harm.
