With engine shut down and the ignition key removed, use
your finger to exert a pressure of about 10 kg (22.0 lb) at
the centre of the belt.
The tension slack should be between about 6 mm (0.2 in)
and 8 mm (0.3 in).
NOTE: Check if there are any signs of wear damage to
the pulleys or the belt. Check carefully to ensure that the
belt is correctly positioned in the pulley grooves. If the belt
is stretched, cracked or frayed, it must be replaced.
