Prep checklist
- • correct engine air filter
- • correct cabin filter
- • small trim tool or screwdriver if needed
- • shop vacuum or towel for loose debris
Filters are beginner-friendly and make the site feel practical fast. They also teach people how to open housings, inspect debris, and reassemble parts correctly.
Stop if the housing is broken, the tray is full of standing water, or airflow problems clearly point past a simple filter service.
