Chevrolet Aveo Cruze 2009–2010 1.6L G3 (Mexico and USA) F14D4 F16D4 A16XER Z16XER Complete Cylinder Head Lacetti Daewoo Nubira Opel Astra 16V – OEM 55565452

Product Overview: This complete cylinder head assembly is designed for GM, Chevrolet, Opel and Daewoo 1.4 and 1.6-litre 16-valve petrol engines in the F14D4, F16D4, A16XER and Z16XER families. It is supplied as a fully assembled unit with pre-installed valves, guides and seats and is machined to original equipment tolerances, offering a reliable replacement for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-strength aluminium alloy and CNC-machined for accurate deck flatness, valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are pre-installed and 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 layout. Intake and exhaust flanges are precision machined for reliable gasket sealing, and cooling passages match the factory design.

Vehicle Compatibility: This head fits Chevrolet G3 Mexico and USA (2009-2010), G3 Wave Canada (2009-2010), Cruze and Lacetti Premier J300 (2009-2016), Cruze 5 (2012-2016), Gentra T255 (2006-2011) and Cruze Wagon GMSA (2013-2017) models, plus related Aveo, Opel Astra and Daewoo Nubira applications using these engine codes. Verify the engine code and OE reference before ordering.

OEM / Reference Numbers: 55565452, 55578489 and 55570930. Match these references against the casting marks on the original cylinder head to confirm the correct variant.

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

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant and combustion gas leakage caused by cracking or distortion, and removes the expense of separately reconditioning valves, guides and seats. A complete unit reduces downtime and simplifies the repair.
