Installation

Cylinder head bolt replacement requires removal and reinstallation of the cylinder head, which is an intermediate-to-advanced repair. Subaru specifies a precise torque sequence and torque angle for EJ253 head bolts — always consult the factory service manual (FSM) for the correct procedure. Note that cylinder head bolts are often torque-to-yield (TTY) fasteners; inspect the old bolt for stretch before reuse, and replace with a new bolt when in doubt. Professional installation by a Subaru-trained technician is recommended.
