Refilling coolant
Coolant helps keep the gasoline engine at the
proper operating temperature. The heat transfer-
red from the engine to the coolant can be used
to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package and use the recommended amount
of coolant. Never fill the cooling system with
water only; this could lead to freezing, corrosion
and engine damage.
WARNING
If the engine has been running, the coolant
will be very hot. Allow the engine to cool
before opening the coolant expansion tank. If
this is not possible, open the cap very slowly
to allow pressure to dissipate.
Lift the rubber strip by pressing it inward in
the engine compartment.
Remove the plastic cover by folding out the
catch and lifting the cover upward.
Remove the expansion tank and add coolant.
The level should be between the
MIN
and
MAX
marks on the tank.
Put the other components back in place in the
reverse order.
