Maintenance Guidelines

• Engine Coolant Level –
Check/Correct:
With the engine off and
temperature cool:
° Check coolant level. It should
be visible through the clear
plastic surge tank.
° Add coolant as necessary by
removing the pressure cap on
the neck of the surge tank or
sight glass.
° Replacement or top up
coolant should have the same
antifreeze concentration and
corrosion inhibitor content
as the original coolant in the
cooling system.
° Always dilute antifreeze to
the correct concentration
based on freeze protection
before adding it to the cooling
system. Adding or using 100%
antifreeze in a cooling system
may result
in cooling system
plugging and overheating
problems.
