Belt check

Check the belt regularly to make sure it is in good condition and is clean. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation of the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and requires no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.

Check coolant level

The cooling system must be filled with coolant and not leak to operate at maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the engine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Frequent removal may prevent
coolant circulation between the engine and the expansion tank during engine warm up and cooling.
