✅ Service Tip: The cylinder head assembly is typically replaced during engine overhaul, when the cylinder head is damaged (cracked, warped), or when valve seats are severely worn. When installing a new cylinder head, always use a new head gasket and tighten the cylinder head bolts to the specified torque and sequence. Valve clearance must be adjusted after installation.

⚠️ Installation Note: Thoroughly clean the cylinder block mating surface before installation, ensuring no old gasket residue remains. Install a new head gasket and position the cylinder head assembly. Tighten the cylinder head bolts in the sequence and torque steps specified in your service manual. After installing the timing system, rotate the crankshaft to check for interference. Start the engine and check for abnormal noise and leaks, then adjust valve clearance.
