Installation

Installation of an engine cylinder head is a complex procedure requiring professional mechanical expertise, precision torqueing to Subaru factory specifications, and the use of new head bolts, gaskets, and seals. This is not a bolt-on DIY repair — professional installation by a qualified Subaru technician or experienced engine builder is strongly recommended. Always consult the Subaru factory service manual (FSM) for torque specs, re-torque procedures, and assembly sequences specific to the EJ253 engine.
