COOLING SYSTEM
Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.

COOLING SYSTEM
NOTICE: Hardware that is removed must always be
installed in its original position unless otherwise
specified. If torque values are not specified, refer to
the Torque Specifications Table. See SCHEDULED
MAINTENANCE CHART on page 166.
Coolant
The use of incompatible coolant will cause insufficient
cooling of the engine. Combining different coolants can
trigger a chemical reaction and cause loss of effective-
ness. The recommended coolants listed have been
tested for compatibility by the engine manufacturer. Verify
compatibility of any coolant not recommended in the list
before use. See RECOMMENDED LUBRICANTS AND
FLUIDS on page 168.
Adding tap water to the coolant will
cause mineral deposits to accumu-
late in the system. This can cause
reduced coolant flow and lead to overheating the
engine.
An incorrect mixing ratio reduces the cooling capacity.
When topping off coolant, do not change the mixing ratio.
The engine coolant is a 50/50 mixture of ant-freeze and
distilled water.
The vehicle requires Ethylene Glycol coolant that is sili-
cate and nitrate-free and suitable for aluminum engines:
See
GENERAL SPECIFICATIONS on page 161. See
RECOMMENDED LUBRICANTS AND FLUIDS on
page 168.
Reservoir Coolant Level
Fig. 2 Coolant Reservoir
Check the coolant level when the engine is cold.
1.
Verify that the coolant level in the reservoir is
between the MIN and MAX lines (Ref. Fig. 2).
2. If the level is below the MIN line, add coolant.
3. Remove the cap from the coolant reservoir.
4. Add coolant until the level is between the MIN and
MAX lines.
5. Replace the cap.
6. Start the engine and allow it to idle for 10 seconds.
7. Recheck the level to make sure it is correct.
NOTICE: If coolant runs low often, or if the coolant
reservoir runs completely dry, check for leaks within
the cooling system.
Radiator Coolant Level
Fig. 3 Radiator Cap
NOTICE: The following procedure is only to be used
for filling a radiator that has not run completely dry.
Refer to coolant replacement if the radiator has
been completely emptied.
If the coolant reservoir has run dry, the coolant level
in the radiator must be checked.
Steam from the radiator can cause
burns if the pressure cap is
removed when the engine is warm
or hot. Do not remove the radiator pressure cap
while the engine is warm of hot. Always allow the
engine to cool before removing the pressure cap.
Check the coolant level when the engine is cold.
1.
Slowly remove the radiator pressure cap (Ref. Fig.
3).
2. Observe the coolant level through the opening. The
coolant level should be level with the filler neck.
3. Use a funnel and slowly add coolant if it is low.
NOTICE: Make sure the engine speed is held at 1900
- 2200 rpm for 15 - 20 seconds so the water pump
has enough force to push all the air out of the sys-
tem. If the engine is allowed to idle, the water pump
seal and valve shaft seals can be damaged.
4. Run the engine at 1900 - 2200 rpm for 15 - 20 sec-
onds to push the air out of the system.
Reinstall the radiator cap.
