7. At each area checked, the probe shall be moved around the
location, at a rate no more than 25-50 mm/s and no more
than 5 mm from the surface completely around the position.
Slower and closer movement of the probe often helps locate
the exact position of the leak.
8. An apparent leak shall be verified at least once by blowing
shop air into the area of the suspected leak, if necessary,
and repeating the check of the area. In cases of very large
leaks, blowing out the area with shop air often helps locate
the exact position of the leak.
9. Leak testing of the evaporator core while in the air
conditioning module shall be accomplished by turning the air
conditioning blower on high for a period of 15 sec. minimum,
shutting it off, then waiting for the refrigerant to accumulate
in the case for time specified by paragraph 10, then inserting
the leak detector probe into the blower resistor block or
condensate drain hold if no water is present, or into the
closest opening in the heating/ventilation/air conditioning
case to the evaporator, such as the heater duct or a vent
duct. If the detector alarms, a leak apparently has been
found.
10. The accumulation time shall be 10 minutes.
11. Following any service to the refrigerant system of the
vehicle, and any other service which disturbs the refrigerant
system, a leak test of the repair and of the service ports of
the refrigerant system shall be done.
