Cleaning and testing the Auxiliary Air Valve

Cleaning and testing the AAV or Auxiliary Air Valve



OK, here it is, the Auxiliary air valve before cleaning...




1970 Volvo AAV









I used detergent to clean it, then rinsed in water followed by alcohol. It still needed some shine, so some buffing and polishing followed. The inside was sprayed out with WD40 to make sure it didn't rust, and to ensure that the piston could move freely.

It was tested by placing it in the fridge to see if it opened, and then  the bulb was placed in boiling water to see if it closed. All checked out OK! Ready to go!








Bosch 0 280 140 013 AAV

    Hi
    I've seen that a similar one is used in Mercedes 280xx

    Does this one fit in a P1800 ES?
