DRIVE BELT - CHECK TENSION

As the drive belt is automatically tensioned, no tension
check or adjustment should be necessary. If the drive
belt is believed to be slack carry out the following
checks:

1. Visually check drive belt tension.
2. Watch movement of tensioner with engine

running, 5 mm ’bounce’ is normal. If tensioner
movement is 12 mm or more, fit a new tensioner.
See Drive Belt Tensioner

3. Inspect tensioner. Is the tensioner arm and

spring case in contact? If so fit a new tensioner.

4. Using a recognised drive belt tensioning gauge,

check belt tension several times, running engine
between checks. The checks should be made at
the same point on the belt, away from the
tensioner.

Drive belt tension, with used tensioner and used drive
belt should be more than:-

270N. Non air conditioning or
295N with air conditioning.
