Toyota 86 2016- 1NZ 2NZ Del Motor Parts 11101-21034 11101-21031 1NZ-FE 1NZ 2NZ Cylinder Head Auris Ist Probox Belta Echo Sienta – OEM 11101-21033

Product Overview: This complete cylinder head assembly is engineered for the Toyota 1NZ, 2NZ and 1NZ-FE 1.3 and 1.5-litre four-cylinder petrol engines, the compact powerplants fitted to the Auris, Ist, Probox, Belta, Echo, Sienta and related models. It is supplied with valves included and machined to original equipment tolerances, providing a dependable replacement for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides are fitted and seats are honed for even sealing and balanced compression across all four cylinders, and the cam carrier surfaces are finished for correct bearing clearance in the DOHC 16-valve valvetrain. Intake and exhaust flange faces are machined to original profiles for reliable gasket sealing, and cooling passages follow the factory design for uniform heat distribution.

Vehicle Compatibility: This head fits Toyota 86 (2016 onwards), Prius (2022 onwards), Platz (2000-2005), Raum (2000-2011) and Porte and Spade (2012-2020) models, together with related Corolla, Vios, Belta, Lexus IS and CT200h applications that use the 1NZ or 2NZ engine. Always confirm the engine code, casting number and OE reference before ordering.

Specifications: Engine code 1NZ / 2NZ / 1NZ-FE; displacement 1.3 L and 1.5 L; inline four-cylinder petrol; DOHC 16-valve; material cast iron or aluminium; standard size; new condition; valves included; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 11101-21033, 11101-21034 and 11101-21031. Cross-reference these numbers with the casting marks and part label on the original head to confirm the correct variant.

Applications: Suitable for compact hatchbacks, sedans, small MPVs, hybrids and city cars, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance programmes requiring a factory-specification head.

Benefits / Replacement Information: Installing this assembly restores compression, corrects coolant and combustion leakage caused by cracking or distortion, and avoids the expense of re-machining the original casting. A complete unit keeps repair turnaround short and ensures factory-matched sealing.

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Clean and check the block deck for flatness, use new head bolts where specified, and torque in the correct sequence to the manufacturer's specification. Replace the head gasket, timing components and coolant, verify cam timing and valve clearances, then pressure test and bleed the cooling system before road use.
