Fuel Injector cleaning steps:

The fuel injector cleaning steps follow by Injector Rx allows for the inspection of all operational aspects of the fuel injectors.

  1. fuel injector cleaning steps check for bad spray patterns

    Our cleaning steps will detect bad fuel injector spray patterns as well as leaking injectors

    Injectors are ohm tested for resistance. If they fail this test no further attempt will be made to clean them.

  2. Then the dirty injectors are externally cleaned, visually inspected, and numbered.
  3. Leak testing is done.
  4. The fuel injectors are then tested for inductance, shorts, and current draw.
  5. Now spray pattern, and injector flow rate tests are performed and recorded.
  6. Filter baskets, O-rings, and pintle caps are removed if needed or where applicable .
  7. A three step ultrasonic cleaning process is performed. During this processes the injectors are pulsed at various rates. This ensures complete results. Only biodegradable environmental friendly chemicals are used .
  8. After ultrasonic cleansing a high pressure back-flush is performed to remove any remaining particles that might be left inside the injector and to flush out water based ultrasonic cleaning fluids.
  9. The injectors, fuel or air, are now retested for: leaks, spray pattern and flow, and the results are recorded.
  10. New filter baskets, O-rings, and pintle caps are installed if and where applicable.
  11. The injectors are lubricated and placed in sealed Poly bags.
  12. A comprehensive test report is prepared and returned with the injectors.

Injector Flow Testing:

($12.00 per injector)

  • Injectors are flow tested only. No additional service is performed and no components are replaced. Flow test results are recorded. Upon completion of the the flow test the injectors are lubricated and sealed in Poly bags.

Long Term Storage:

(No Extra Charge.)

  • The “Clean and Flow” service is performed
  • The injectors are lubricated with special lubricant.
  • The injectors are sealed in Poly bags.

Although there are many fuel injector cleaning methods, our cleaning steps, fuel injector flow testing procedures and equipment are approved by major fuel injector manufacturers.
