the power switch off and the battery
switch turned off to avoid contact with
moving parts.
• When there is not enough tension in the
V-ribbed belt, it will slip and the coolant
pump will fail to supply coolant. Engine
overheating and seizure will result.

the belt causes slipping and stretching.
Replace the belt if it is damaged.
