A complaint of intermittent engine
noise can be difficult to verify. As a
part of routine predictive mainte-
nance, you could determine that
the perceived belt noise is actually
a result of decoupler pulley slip-
page, and replace it before total
decoupler failure occurs.
Measure the cooling capacity of
the condenser, or quickly scan
the whole condenser for hot or
cold spots. You can use a similar
method to diagnose radiators.
