HEAD - ENGINE CYLINDER BARE (Toyota TY110173020)

A damaged cylinder head can allow compression loss or coolant leakage into the combustion chamber. During a top-end overhaul, the head's sealing surface condition directly affects engine performance. This aftermarket replacement part references Toyota catalog number TY110173020. The head is the bare casting that caps the cylinder block and forms the upper combustion chamber. A warped or cracked head often causes overheating or misfire from failed gasket sealing. Keeping the head flat and crack-free helps maintain proper compression and cooling system integrity. Verify the serial number or application, then call (562) 693-7748.
