Phase Two - SPX LeakMaster 6525 Manual Del Operador

1. Verify the vehicle's fuel level is below the base of
the fuel tank neck.
2. Position the selector valve on the tester to SMOKE.
See Figure 8.
3. Remove the vehicle's fuel cap.
This saves time when filling the EVAP system with
smoke.
4. Press the remote starter button to activate the tester.
The "ON" indicator light will come ON after a
5-second self-diagnostic delay, indicating the tester
is ON and producing smoke.
5. Replace the fuel cap once smoke is seen exiting the
fuel tank's neck.
The timer will automatically turn OFF in five minutes.
To shut the tester OFF before the five minutes are up,
simply press the remote button.
6. Continue to introduce smoke into the EVAP system
for about 60 seconds, or until the flow meter's ball
stops descending.
It is not necessary to wait until the system is full
(indicated by the descending flow meter ball) before
looking for leaks.
7. Use the spotlight provided to follow the EVAP
path and look for smoke exiting a leak. Continue to
introduce smoke in 30 second intervals until the leak
is found.
This ON/OFF technique allows the EVAP system to
achieve test pressure, and then allows the pressure to
be relieved. Diagnostic Smoke
visible at lower test pressures.
You could also use a UV light (not provided) to search
for the UltraTraceUV
at the exact location of the leak(s). The longer the
EVAP system is allowed to fill with Diagnostic
Smoke ® vapor, the more fluorescent material will be
deposited.
8. Repair the leak(s), and perform the Phase One test
again to verify the repair and make certain there are
no additional leaks in the EVAP system.
9. Reinstall the vehicle's Schrader valve using a
counterclockwise thread rotation (OBD vehicles
only). Reinstall the EVAP service port green cap.
® vapor is even more
®
dye that would be deposited

Tech Tips
• For an even quicker test procedure, it is
possible to combine Phase One and Phase
Two. The flow meter is operational in both
phases.
If you already know the EVAP system has a
leak, start with Phase Two testing. (The leak
will still be quantified, because the flow meter
is active.)
Then perform Phase One to verify the repair.
• If you are testing a vehicle that has a fuel roll-
over valve in the fuel tank, you may not see
smoke exiting the fuel tank neck.
You may need to introduce smoke through the
fuel tank neck, and vent the non-smoke air out
the vehicle's service port; or at least partially
fill the system with smoke before closing the
vent solenoid. Then, once smoke is seen exiting
the vent area, close the vent solenoid.
