CHECKING COOLANT LEVEL
WARNING
Do not remove cooling system fi ller cap when
the engine is hot. Allow the engine to cool and
then remove the pressure cap slowly, allowing the
pressure to vent. Hot coolant, under pressure, may
discharge violently and cause severe burns.
Degas Bottle
The “see-through” degas bottle is connected to the
heat exchanger by a small hose. The degas bottle
collects coolant that expands with rising temperature,
and would otherwise overfl ow from the system. Coolant
level should be at or slightly above the “ADD” mark on
the bottle when the system is cold. Coolant should be
added ONLY to the bottle when the system cools. Add
specifi ed coolant as required.
