Toyota 86 2016- 1ZZ 11101-22071 11101-22052 Aluminum Cylinder Head 1ZZ 2ZZ 1ZZ-FE ForToyota Corolla Previa Prius Lexus – OEM 11101-22071

Product Overview: This complete cylinder head assembly is a direct-fit replacement engineered for Toyota 1ZZ engines. It is supplied fully assembled with valves, guides and seats installed, so a cracked, warped or valve-damaged original head can be replaced without additional machining work.

Key Features: CNC machining holds deck flatness, valve seat concentricity, valve stem protrusion and port geometry to original equipment limits. Guides and seats are fitted and honed so sealing is even and compression is balanced across all cylinders, giving a stable idle. Internal coolant galleries follow the original casting layout so heat is removed evenly from all cylinders. The machined cam carrier faces keep bearing clearances within specification for correct camshaft rotation.

Vehicle Compatibility: Compatible applications include Toyota, with listed fitment across COROLLA SED (JPP), COROLLA (MEXICO), SCION IM/IM, Scion XB, SCION FR-S/86 and COROLLA HATCHBACK. Fitment is documented for the 2000-2000, 2013-2019 and 2000-2001 model years. Always check the engine code and the reference number on the original part against the listing to ensure the correct variant is supplied.

Specifications: Key specifications: engine code 1ZZ; material Cast Iron or Aluminium; size Standard Size; condition New; warranty 12 Months. It is supplied for replacement and repair applications in standard specification. The assembly is supplied in standard size and is pressure tested before packing to confirm casting integrity.

OEM / Reference Numbers: OEM and cross-reference numbers covered by this listing are 11101-22071, 11101-22101, 11101-22052, 11101-22051 and 11101-0D031. Match the numbers above against the markings on the removed part to be certain of correct identification.

Applications: Typical applications include head gasket failure repairs, valve damage repairs, engine rebuilds and fleet maintenance on vehicles with cracked or distorted cylinder heads. It also suits preventative maintenance programmes where a failed unit is replaced before secondary damage occurs. The part is a sensible stock item for workshops that service this engine family regularly and want to minimise vehicle downtime.

Benefits / Replacement Information: Fitting this assembly restores compression, eliminates coolant loss through cracked castings and returns consistent combustion. Because the unit is supplied fully assembled and pre-machined, it removes the labour and risk involved in reconditioning a warped or cracked original head. The repair stays within original equipment specification, which is important for vehicles that remain in daily commercial service.

Installation or Fitment Notes: Check the reference number and engine code first, then inspect the block deck for flatness and distortion. Fit a new gasket and, where required, new torque-to-yield bolts, ensuring the bolt holes are clean and free of fluid.
