EVAP System Leak Inspection (EVAP Leak Check Model): Notes

WARNING: Failure to take proper precautions when performing the leak inspection of the EVAP system may result in death, serious injury or fire.
  • Be sure to read, understand and follow all instructions in the WARNINGs, CAUTIONs and NOTICEs as well as in the operating procedures.
  • Be sure to use only nitrogen gas for this inspection. If any other gas is used, the gasoline in the fuel system may ignite and explode.
  • Handle compressed nitrogen correctly. Contact your local supplier of compressed gases for the procedures to follow and precautions to observe to correctly handle compressed nitrogen.
  • Wear eye protection that meets OSHA standards.
  • Perform the tests only with the engine stopped.
  • Close nitrogen cylinder valve after completing test.
  • The halogen lamp is very hot when it is lit. Do not touch the top part or lens of a hot halogen lamp or place it near flammable items. Wait until the halogen lamp cools down before storing it.
  • Do not perform the test near a spark or heat source. Leaking fuel or gasoline vapor may catch fire.
  • Use only the Ultra Trace UV™ smoke producing fluid specified by the tester manufacturer.
CAUTION: Failure to take proper precautions may result in damage to or operational problems with the testing equipment and vehicle systems.
  • Use the tester only in the manner specified by the manufacturer.
  • Use the smoke-producing fluid only for testing the evaporative emission system. This fluid will degrade the performance of vehicle systems other than the evaporative emission system.
  • Connect the tester correctly to the battery and the chassis ground connection.
  • Operate and store the tester only in its upright positions.
  • Use the halogen light or optional UV™ light intermittently to prevent overheating.
  • If the smoke leak test is performed more than 5 times for the same vehicle, the performance of the EVAP canister will deteriorate. Replace the EVAP canister if the evaporative emission control system has undergone the leak test 5 times.
NOTE: Change the Ultra Trace UV™ Smoke Producing Fluid in the tester once a year.
