Product Features:

• OEM Part Number: 0JYA-026000-20000
• Product Name: Rear Cylinder Head Sub-Assembly
• Material: High-Strength Alloy
• Model Years: 2017-2020 (See list below)

• Forms Combustion Chamber: Works with the cylinder and piston to create the space where fuel combustion occurs.
• Houses Valve Train: Provides the precise mounting and operational base for camshafts, valves, and spark plugs.
• Efficient Heat Dissipation: Integrated coolant passages rapidly carry away combustion heat, preventing engine overheating.
• Ensures Sealing: Works with the head gasket to seal high-pressure gases and engine oil, preventing leaks.
• Guides Intake/Exhaust: Precisely designed intake and exhaust ports optimize airflow, improving engine volumetric efficiency and power output.

✅ Fault Indications: Common signs of cylinder head-related issues include:
• Rapid coolant loss, white smoke from exhaust (blown head gasket);
• Milky white engine oil (coolant mixing with oil);
• Loss of power, rough engine operation, or failure to start (valve leakage);
• Visible oil or coolant residue on cylinder head mating surfaces.
If you encounter these issues, inspect or replace the cylinder head assembly promptly.

✅ Installation Tip: When replacing the cylinder head, a new head gasket and intake/exhaust manifold gaskets must also be installed. Thoroughly clean the engine block deck surface before installation. Cylinder head bolts must be tightened in multiple stages following the specific sequence and torque values outlined in the service manual. Professional installation by an experienced technician is highly recommended.
