TIRES: Sweep the tire, including the rim and valve system, to
search for leaks. A sweep with the ultrasonic receiver will locate
even the smallest of leaks. The receiver normally finds leaks of
sufficient magnitude before they cause downtime on the highway.
In addition, you can put a soap solution on tires and listen for the
bubbles to pop. Use the hollow air probe or use the receiver
alone.
LEAKING ENGINE VALVES: All valves should emit a sound in a
very close meter and sound pattern when the probe is placed on
the intake manifold opposite the intake port. A suspect valve can
then be positively checked, with the engine off, by bringing that
particular cylinder to full compression and placing the probe on the
valve stem. The “hiss” of escaping gas across the valve seat will
be distinctly audible on the leaking valve. You can use the same
procedure to check exhaust valves, but the signal intensity will be
much greater. Use the solid contact probe.
EXHAUST SYSTEMS: With the engine idling, pulsation in the
exhaust system can be detected with the receiver. Leak points
normally give off a much louder and sharper sound. Use the
hollow air probe or use the receiver alone.

TANKS: When placed
inside a vehicle, a
completely empty fuel
tank or any other
enclosure, the activated emitter can easily locate leaks in weather-
stripping, seals or the structure itself. Use the hollow air probe or
use the receiver alone.
