LIQUID COOLING SYSTEM

VIEW
The engine coolant level is controlled or maintained
by the recovery system. The recovery system
components are the recovery bottle, radiator filler
neck, radiator pressure cap and connecting hose.

coolant levels often during the break-in period.
Overheating of engine could occur if air is not fully
purged from system.

COOLANT STRENGTH / TYPE
Test the strength of the coolant using an antifreeze
hydrometer.
Antifreeze Hydrometer
S A 50/50 or 60/40 mixture of antifreeze
and distilled water will provide the
optimum cooling, corrosion protection,
and antifreeze protection.
S Do not use tap water, straight antifreeze,
or straight water in the system. Tap water
contains minerals and impurities which
build up in the system.
S Straight water or antifreeze may cause
the system to freeze, corrode, or
overheat.

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).
RADIATOR
A
B
1. Check radiator (A) air passages for restrictions or
damage. Check and clean the radiator screen
(B).
2. Carefully straighten any bent radiator fins.
3. Remove any obstructions with compressed air or
low pressure water.
