Connect nitrogen or shop air supply hose to the quick-connector shown below.  The EVAPro comes with a built-in regulator that allows you to use nitrogen for all EVAP testing or shop air for all of your general purpose leak detection needs.

Choose the proper EVAP port adaptor for the Vehicle from the accessory kit.

The Schrader removal tool is used for taking the core out of the EVAP service port.

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.

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.

For the purpose of this presentation, we will use the .040” standard.

1. Position the Tester’s selector switch to the .040” calibration.

2. Turn the Tester ON. 3. Set the Pass / Fail mark by

using your thumb to align the red pointer flag with the ball.

Now the red flag is set to equal a .040” leak and it is calibrated for that vehicle.

Remember to calibrate for .040” or .020” before each test.Click here for next screen

Power ON Check Oil

Use scantool and close Vent Solenoid

If scantool doesn’t close vent solenoid,

refer to Tech Tip Booklet

Vent Solenoid NO - OFF

To activate vent solenoid

Push YES to turn ON

Push NO to turn OFF

TPS 2.5V

FTL 58%

At first the ball will go to the top of the flow meter.

The ball will slowly drop until it no longer goes down.

3. Once the ball stops moving downward, check the alignment with the red flag.

If the ball is below the red flag, the leak(s) are less than .040”; PASS

If the ball is above the red flag, the leak(s) are greater than .040”; FAIL

Go to Phase Two.

Five minutes after turning the Tester ON, it will turn off automatically.

1. Set selector switch to TEST.

2. Close EVAP vent solenoid.

3. Turn the Tester ON.

Phase Two

1. Set selector switch to SMOKE.

2. Turn the Tester ON.

3. Look for Smoke and/or dye exiting the leak(s).

Look for the smoke or the ultraviolet-activated

fluorescent dye.
