Hyundai I20 18 (2018-2020) 2018-2020 G4GC G4GC Complete Cylinder Head 22100-23740 22100-23701 Sportage/Tiburon – OEM 22100-23780

Product Overview: This complete cylinder head assembly is engineered for Hyundai and Kia G4GC 2.0-litre 16-valve petrol engines used across a broad range of passenger and light commercial models. It arrives fully assembled 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 material and CNC-machined to hold accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are fitted and honed for even sealing and balanced compression, while the cam carrier surfaces are finished to maintain correct bearing clearance for the DOHC valvetrain. Intake and exhaust flange faces are machined to original profiles for reliable gasket sealing, and coolant passages follow the factory layout.

Vehicle Compatibility: This head suits Hyundai i20 18 (2018-2020), H-1 (2006-2008), Elantra and Lantra 96 (1995-2001), Trajet (2006-2008), i30 20 (2020 onwards) and Grandeur (2006-2010) models, together with related Kia Sportage, Coupe and Tiburon applications powered by the G4GC engine. Verify the engine code and OE reference before ordering.

Specifications: Engine code G4GC; displacement 2.0 litres; inline four-cylinder petrol; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; intended for replacement and repair.

OEM / Reference Numbers: 22100-23780, 22100-23760, 22100-23740 and 22100-23701. Match these references against the casting identification on the original cylinder head to be certain of the correct specification.

Applications: Suitable for family sedans, coupes, MPVs, small SUVs and light commercials, covering routine repairs, engine overhauls, rebuilds and fleet maintenance where a durable factory-specification head is needed.

Benefits / Replacement Information: Replacing a failed head with this assembly restores compression, eliminates coolant and combustion leakage, and resolves overheating caused by distortion or cracking. Supplying the head complete avoids the lead time and cost of individually reconditioning valves, guides and seats.

Installation or Fitment Notes: Entrust installation to 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 and cooling components as required, verify valve clearances and cam timing, then run the engine and confirm there are no leaks before road testing.
