Toyota For Toyota Lexus 1AZ 2AZ 11101-28011 Engine 1AZ 2AZ FSE 1AZ-FE 2AZ-FE Complete Cylinder Head Camry Corolla Hiace Liteace Sapcio Lexus – OEM 1110128011

Product Overview: Designed as a complete replacement cylinder head for 1AZ, 2AZ engines, this assembly arrives ready for fitment with valve seats and guides already installed. It serves Toyota Lexus platforms and reproduces the original chamber volume, port shape and camshaft bearing alignment. Every head is inspected and pressure tested before shipment and is supplied new with a 12-month warranty. It is intended for replace/repair use and is a cost-effective alternative to reconditioning a damaged original head. The unit is inspected for flatness and gallery cleanliness prior to dispatch, ensuring it is ready for immediate fitment.

Key Features: Manufactured in High-Strength Aluminum Alloy, this cylinder head is machined on CNC centres to original tolerances for deck flatness, valve seat alignment and port volume. Seats and guides are fitted and honed, and chamber volumes are equalised across cylinders for even compression and smooth running. Thickened sections around the valve bridge and combustion bowl resist thermal cycling, and the precision-machined cam carrier keeps bearing clearances within specification. The casting is dimensionally stable and accepts original-specification gaskets, bolts and ancillary components.

Vehicle Compatibility: Compatible applications include make; model; year; engine. Verify the engine code and OE number cast or stamped on the original head before purchase, since a single model line can use more than one casting revision.

Specifications: Engine code / family: 1AZ, 2AZ; Displacement: 2.0 L / 2.4 L; Cylinder configuration: Inline-4; Valve train: DOHC 16V with VVT-i; Material: High-Strength Aluminum Alloy; Size: STD; Surface treatment: Heat Treated Valve Seats / Nitrided Cam Journals; Condition: New, supplied for replace/repair use; Warranty: 12 Months; Items included: Valve; Certification: ISO 9001 / IATF 16949; Packaging: neutral export carton.

OEM / Reference Numbers: Applicable OEM and reference numbers are 1110128011, 1110128012. Compare the stamped or cast numbers on the removed component with this list, as several revisions may exist within a model range.

Applications: Typical applications include Toyota Lexus passenger cars, vans and light commercial vehicles, covering routine workshop repair, preventive maintenance and full engine rebuilds.

Benefits / Replacement Information: Replacing a damaged original with this ready-built assembly restores compression and combustion sealing while avoiding the labour and lead time of separate valve and seat work. Coolant leaks, cross-cylinder gas transfer and compression imbalance caused by cracks or warping are resolved in one operation.

Installation or Fitment Notes: Installation requires a clean, flat block surface and correctly cleaned bolt holes. Use a new gasket of the correct type and thickness, fit new fasteners where torque-to-yield bolts are specified, and tighten in the prescribed sequence. Refill and bleed the cooling system with the recommended coolant, then re-check levels after the first heat cycle.
