Using a funnel, add coolant until the fluid level is to
the top of the filler neck.
6.
Reinstall the pressure cap and install the front
access cover.
Cooling System Hoses
1.
Inspect all hoses for cracks, deterioration, abrasion
or leaks. Replace if necessary.
2.
Check tightness of all hose clamps.
CAUTION
Do not over-tighten hose clamps at radiator,
or radiator fitting may distort,
causing a restriction to coolant flow.
Radiator hose clamp torque is 36 in-lbs (4 Nm).
Cooling System Pressure Test
System Pressure Test
1.
Remove radiator cap cover located under the
storage box access panel. See Chapter 3.
2.
Remove recovery bottle hose from coolant filler.
3.
Connect a Mity-Vac™ (
PN 2870975
) to radiator and

must retain 10 lbs of pressure for five minutes or
longer. If pressure loss is evident within five minutes,
check radiator, all cooling system hoses and clamps,
or water pump seal.
