Note
l Measure the belt deflection between the specified
pulleys.
l A belt is considered “New” if it has been used on
a running engine for less than five minutes.
Set the deflection specified below accordingly.
l Check the belt deflection when the engine is cold,
or at least 30 minutes after the engine has stopped.
