Installation

The PCV Hose Assembly is generally a straightforward replacement that can be performed by a knowledgeable DIYer with basic hand tools. Locate the existing PCV hose, release any clamps or retaining clips, remove the old hose, and install the new Genuine Subaru unit. Always inspect surrounding PCV system components (valve, grommets, other hoses) for wear at the same time. If you are unsure, professional installation by a Subaru-certified technician is recommended to maintain your warranty coverage.
