BEFORE YOU START
Match the car. Then the instructions.
This document concerns the under-bonnet cowl filter. It does not establish that every filter in the car’s ventilation system has been serviced.
- Use the catalogue to check the exact engine, production date and steering position before ordering parts.
- Compare your installed housing and fasteners with the illustrations. Stop if the arrangement differs or the instructions leave a safety-critical detail unresolved.
- Follow the publisher’s precautions. Fitting requires relevant mechanical knowledge and experience.
