BLEEDING PROCEDURE FOR 4--STROKE COOLING SYSTEMS
Use this procedure when a unit overheats and no appar-
ent leaks in the cooling system are found.
Note: If the coolant level is LOW in the radiator, or if there
are leaks in the system, the coolant system will not draw
coolant from the reservoir tank.
1. Park Machine on a flat surface. Remove radiator cap and
top off coolant. Leave the cap off of the radiator. Start and idle
machine for 5-10 minutes until steam is visible in the radiator
cap area.
2. Stop the engine and let cool for a few minutes or until a
“glug” is seen at the filler neck or there is a dropping of the
coolant level, indicating that coolant has been pulled into the
system.
Important Tips: Slowly squeezing the hose after the bend
below the filler neck will aid in purging the system of air.
Pump the hose using your hand several times as shown in
the diagram. Elevating the rear of the ATV with a floor jack
(rear tires 4-6, off the ground) also aids the purging of air from
the system.
3. Always add coolant to the radiator first,
filling to the top of
the neck to replace air that has been purged from the system.
Fill the reservoir only after you have completely filled the coo
l-
ing system at the radiator filler neck
.
4. Repeat Steps 1 and 2 four or five times or until no more
coolant is pulled into the system.
5. In some instances, Steps 1 and 2 may have to be per-
formed with the radiator cap on to prevent coolant loss.
6. To test, install the radiator cap and idle machine until fan
comes on. Make sure the fan comes on before the hot light.
