Depending on the test you are performing, connect either an inert gas, such as Nitrogen, or shop air supply line to the EELD601 water-separator / filter connection located on the back of the tester

Be sure the supply pressure to the tester is between 50 psi and 150 psi

When testing EVAP systems: Connect the tester to an inert gas, such as nitrogen.

When testing systems other than EVAP: Connect the tester to shop air.

The EVAP port adaptor is used to connect to the vehicles EVAP service port.

The Schrader removal tool is used for taking the core out of

the EVAP service port.

No. WVA-04 No. WVA-09

Because of the volatile fumes that may be present in an evaporative emissions system, we recommend using an inert gas, such as nitrogen, for testing EVAP systems.

Do not perform tests near a source of spark or ignition

TEST SAFELY

Q: Why use Nitrogen to test EVAP system?A: SAE published Paper reports the hazards of using air instead of Nitrogen to test the EVAP system. http://www.sae.org/technical/papers/2007-01-1235  

Q: What is BAR requiring on the California BAR-Certified equipment?A: BAR says only Nitrogen can be used in BAR-Certified equipment, citing “equipment requirements and safety concerns”.  Q: Why do some other smoke machine companies say you don’t need to use Nitrogen with their machines?A: Most likely because their machines are not built with the licensed, patented technology to use nitrogen. Sounds like an attempt to put the best ‘spin’ on a product that CAN’T use Nitrogen.

Note: All current Vacutec smoke machines contain patented technology designed to be used with Nitrogen for safer EVAP testing.

1. Remove the OBD-II service port adaptor cap.

2. With the Schrader removal tool turn clockwise and remove the core from the service port *.

You must remove the core before testing.

[After testing,don’t forget to reinstall the OBD-II service port

Schrader core and cap].

* If the vehicle being tested does not have an EVAP service port, then access the EVAP system at the purge valve line that leads to

the charcoal canister.

To intake manifold

To Charcoal Canister / Fuel Tank

If the car you are working on doesn’t have an EVAP service port and

follow this procedure.Note: See Tech Tip Booklet for more details.

Insert smoke supply hose into EVAP system line going to the charcoal canister.

Note: This does NOT test the purge valve for leaks!

.

Let’s do a step by step EVAP test. Remember that you must use nitrogen!

1. Connect the red lead to positive on battery.

2. Connect the black lead to chassis ground.

A low battery will cause the Tester’s green Power light to blink.

See Trouble Codes in your Operator Manual.Click here for next screen

With power leads connected, the green light should be ON.

Press and release the ON/OFF button to active the EELD601

The tester’s Smoke light will come on, indicating smoke production

The timer will automatically turn OFF in 5-minutes. To turn the tester OFF before the5-minutes are up, simply press the ON / OFF button again.

Note:

If the ball initially never goes to the top of the flow meter, this indicates a restriction in the EVAP system.

Did you remember to remove the Schrader valve from the EVAP service port?

Do you have your nitrogen supply turned on?

Notice that at the beginning of the test procedure, the flow meter’s-ball will go to the top of the flow meter scale

This indicates two things;

A) The EVAP system is being filled and

B) There are no restrictions in the EVAP system at this time.

Now close the vehicle’s EVAP System Vent Solenoid. Usually in less than 60 seconds of activating or closing the vent solenoid (depending on the capacity and fuel level) the flow meter’s indicator-ball will fall within the meter’s visible scale.

Continue to fill the system until the ball stops descending (this could take an additional two minutes).

Once the meter's indicator-ball has stopped descending, align the flow meter’s red flag to theindicator-ball. If the ball descends to the bottom of the meter, this indicates the system has NO leak.

However, if the red flag indicates a leak greater than the allowable standard, continue to introduce smoke into the system and look for the smoke exiting the leak.
