Radiator Coolant Level Inspection

NOTE: This procedure is only required if the cooling
system has been drained for maintenance and/or
repair. However, if the recovery bottle has run dry,
or if overheating is evident, the level in the radiator
should be inspected and coolant added if necessary.
Radiator Cap
WARNING
Never remove the pressure cap when the
engine is warm or hot. Escaping steam can
cause severe burns. The engine must be cool
before removing the pressure cap.
NOTE: Use of a non-standard pressure cap will not
allow the recovery system to function properly.
To access the radiator pressure cap raise the front hood.
The radiator cap is located on the drivers side.

Coolant Strength / Type

Test the strength of the coolant using an antifreeze hydrometer.
Antifreeze Hydrometer
• A 50/50 or 60/40 mixture of antifreeze and distilled
water will provide the optimum cooling, corrosion
protection, and antifreeze protection.
• 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.
• Straight water or antifreeze may cause the system to
freeze, corrode, or overheat.

Cooling System Pressure Test

Refer to Chapter 3 for cooling system pressure test procedure.

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).
