MAINTENANCE
Cooling System
Radiator Coolant Level/Changing Coolant
This procedure is required only if the cooling system has been drained
for maintenance and/or repair. If the overflow bottle has run dry, the
level in the radiator should also be inspected.
CAUTION! Escaping steam can cause burns. Never remove the pressure cap
while the engine is warm or hot. Always allow the engine to cool before
removing the pressure cap.
1. Remove the hood. See page
30.
2. Slowly remove the radiator
pressure cap.
3. View the coolant level
through the opening.
4. Use a funnel and slowly add
coolant as needed.
5. Before reinstalling the
pressure cap, bleed the
system of trapped air.
Remove the engine access
panel behind the seats and
use a flat-blade screwdriver
to turn the bleed screw
slightly, allowing the air to
escape. Slowly add
additional coolant to the
radiator until air no longer
escapes and only coolant
flows from the bleed hole,
then tighten the bleed screw.
6. Reinstall the pressure cap.
Tip: Use of a non-standard pressure
cap will not allow the recovery
system to function properly.
