Liquid Cooling System - Tracker Off-Road 500S Service Manual

Liquid Cooling System

When filling the cooling system, use premixed anti-
freeze. Verify the coolant level in the reservoir tank is
between the FULL and LOW indicator lines. Fill as
needed. While the main cooling system is being filled, air
pockets may develop. Fill the cooling system to the bot-
tom of the stand pipe in the radiator neck. Run the engine
for 3 minutes to allow air to bleed from the cooling sys-
tem. After the initial fill, shut the engine off, and then
"top-off" the cooling system to the bottom of the stand
pipe in the radiator neck. Install the radiator cap.
 NOTE: Use a good quality, biodegradable glycol-
based, automotive-type antifreeze. When filling the
cooling system, use a 60/40 coolant/water mixture or
one which will satisfy the coldest anticipated weather
conditions of the area in accordance with the coolant
manufacturer's recommendations.
! WARNING
Never check the coolant level when the engine is hot or
the cooling system is under pressure.
CAUTION
After operating the vehicle for the initial 5-10 minutes,
stop the engine, allow the engine to cool down, and
check the coolant level. Add coolant as necessary.
COOLING SYSTEM PRESSURE
TESTING
1. Remove the front hood and radiator access panel.
Use a readily available pressure tester. Wet the pres-
sure tester seal; then connect the pressure tester to
the radiator filler neck.
2. Pump the tester up to 12.8 psi (0.9 kg/cm
coolant system should hold this pressure for up to 6
seconds. If it does not, inspect the entire coolant sys-
tem for leaks. Do not exceed 14.9 psi (1.05 kg/cm
when pressure testing the coolant system.
3. To test the radiator cap relief pressure, wet the seal
on the cap. Connect the tester to the radiator cap. The
relief pressure specification for the cap is 12.8 psi
2
(0.9 kg/cm ). If the cap does not relieve pressure as
specified, replace the cap.
RADIATOR
Removing
1. With the vehicle on a flat level surface, set the trans-
mission into the Park position then chock the wheels.
Remove the center and right-side skid plates.
Remove the front hood and radiator access panel.

2. Remove the radiator cap; then drain the coolant into
a suitable container by removing the drain plug
found on the water pump. Account for the washer.
Disconnect the cooling fan wire connector from the
main harness.
