Hyundai I20 18 (2018-2020) 2018-2020 G4GC Factory Manufacturing G4GC Cylinder Head 22100-23760 Kia Coupe/Elantra – OEM 22100-23780

Product Overview: This complete cylinder head assembly is manufactured for Hyundai and Kia G4GC 2.0-litre petrol engines, a widely used four-cylinder found in sedans, coupes and compact SUVs. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, making it 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, 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. Cam carrier surfaces are finished for correct bearing clearance in the DOHC 16-valve layout, and the intake and exhaust flanges are precision machined for reliable gasket sealing and correct manifold alignment.

Vehicle Compatibility: This head fits 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, plus related Kia Coupe, Sportage and Tiburon applications using the G4GC engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code G4GC; displacement 2.0 litres; inline four-cylinder 16-valve petrol; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 22100-23780, 22100-23760, 22100-23740 and 22100-23701. Cross-reference these numbers with the casting marks and part label on the original head to confirm the correct variant.

Applications: Suitable for sedans, coupes, MPVs, SUVs and light commercial vehicles, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance programmes where a factory-specification 2.0-litre head is required.

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

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Clean and check the block deck for flatness, fit a new head gasket and new head bolts as specified, and torque in the correct sequence. Replace timing belt or chain components and coolant during the job, verify valve clearances and cam timing, then run the engine to operating temperature and check for leaks before road testing.
