Ford Focus CB4 2008- 2008-2023 HXJD IQDA IQDB IQDP JQDA JQDB JTDA JTDB 7S7G-6C032-AA 1481576 Cylinder Head Assy for Ford R1.6 1.6L Duratec 16V Ti-VCT Sigma – OEM AE8G-6C062-GA

Product Overview: This complete cylinder head assembly is engineered for Ford 1.6-litre Duratec 16V Ti-VCT Sigma petrol engines fitted to the Focus, Fiesta, B-Max and C-Max ranges. It is supplied as a fully assembled unit with valves, guides and seats installed, machined to original equipment dimensions and inspected before dispatch, providing a bolt-on solution for a cracked, warped or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade aluminium alloy and CNC-machined for accurate deck flatness, correct valve seat concentricity and matched 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 maintain correct bearing clearance for the variable valve timing valvetrain. Machined intake and exhaust flanges ensure reliable gasket sealing, and cooling passages follow the factory design.

Vehicle Compatibility: This head suits Ford Focus CB4 (2008 onwards), Focus CDH (2012 onwards), Focus RS CEW (2016 onwards), Fiesta and Fusion CBK (2001 onwards), Fiesta CCT (2014 onwards), F650 and 750 TBC (2016 onwards) and Ford GT (2017 onwards) models using the 1.6 Duratec Ti-VCT engine. Always confirm the engine code and OE number before ordering.

OEM / Reference Numbers: AE8G-6C062-GA, BM5G-6A258-A, BM5G-6A258-AB, 7S7G-6C032-AA, 7S7G-6C032-11 and 1481576. Match these references against the casting identification on the original cylinder head to confirm the correct variant.

Applications: Suitable for compact hatchbacks, family cars and hot hatch derivatives, covering routine repairs, timing service work, engine rebuilds, workshop overhauls and fleet maintenance.

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and eliminates the cost of reconditioning the original valves, guides and seats individually. A complete unit shortens repair time and reduces vehicle downtime.

Installation or Fitment Notes: Have the head installed by a qualified technician. Inspect the block deck for flatness and clean all mating surfaces, fit a new head gasket and new head bolts where specified, and torque in the correct sequence. Replace timing chain, tensioners and coolant as part of the job, verify variable valve timing set-up, then run the engine to operating temperature and check for leaks before road testing.
