and evaporative emission noises. The Ultrasonic Leak Detector includes a multi-directional transmitter
(operating in the ultrasonic range) and a hand-held detector. The transmitter is placed inside the
vehicle. On the outside of the vehicle, the hand-held detector is used to sweep the area of the
suspected leak. As the source of the leak is approached, a beeping sound is produced which
increases in both speed and frequency.

Tracing Powder
Tracing powder is used to check both the uniformity of contact and the tension of a seal against its
sealing surface. These tests are usually done when a suspected air leak/noise appears to originate
from the seal area or during the alignment and adjustment of a component to a weatherstrip. Tracing
powder can be ordered from Crest Industries as ATR Leak Trace. Carry out the tracing powder test as
follows:
a. Clean the weatherstrip.
b. Spray the tracing powder on the mating surface only.
c. Close the door completely. Do not slam the door.
d. Open the door. An imprint is made where the weatherstrip contacted the mating surface seal.
Gaps or a faint imprint will show where there is poor contact with the weatherstrip.
