Installation

The Oil Control Valve (AVCS) is typically accessed at the front of the engine block near the camshaft timing cover. Installation involves draining a small amount of engine oil, removing the retaining bolt, extracting the old valve, and installing the new one with a fresh sealing O-ring (verify if included or source separately). Torque the retaining bolt to factory specification. Clearing any stored AVCS fault codes with an OBD-II scanner is recommended after installation. Professional installation by a qualified Subaru technician is advised to ensure proper torque specs and system reset procedures are followed.
