Installation & Maintenance Notes
For Freightliner and Western Star trucks using the AF26424 air filter, general service steps include:
- Shut down the engine and allow the air intake system to cool before servicing.
- Open the air filter housing and remove the old primary element (AF26424) first.
- Inspect the secondary element (AF27706) — replace it every 2–3 primary element changes, or immediately if visibly contaminated, and never clean/reuse it.
- Inspect the housing for dust buildup or debris before installing new elements.
- Install the new filter(s), ensuring the seal seats evenly to prevent unfiltered air bypass, and secure the housing cover.
- Recommended replacement interval: follow your truck’s OEM service schedule, typically based on mileage or a restriction indicator reading.
FAQ
Q: Do I need to replace both AF26424 and AF27706 at the same time? A: Not necessarily.
