How to Find Your Hyundai Engine Code

The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Hyundai and DVLA sources

Engine Code

Engine Code

A unique identifier stamped on the engine block or cover used for parts and service.

VIN

VIN

The vehicle identification number that holds encoded vehicle and engine information.

Chassis Number

Chassis Number

The chassis or frame number used for registration and legal identification.

Hyundai i30 (2012–2016)

Hyundai i30 (2012–2016)

Gamma G4FG Engine

Locate the engine code on the timing cover, near the camshaft housing. It is stamped into the metal or on a label near the front of the engine block.

Hyundai Tucson (2015–2020)

Hyundai Tucson (2015–2020)

Theta II G4KD Engine

The engine code is located on a label attached to the timing cover, visible from the front of the engine bay. It reads 'G4KD' for the 2.0L GDI variant.

Hyundai Santa Fe (2013–2018)

Hyundai Santa Fe (2013–2018)

CRDi D4HA Engine

Open the hood and look at the front left of the engine (passenger side). The code is on a label near the timing cover. Confirm 'D4HA' for the 2.2L diesel.

Hyundai i20 (2015–Now)

Hyundai i20 (2015–Now)

Kappa G4LA Engine

The engine code is cast into the front of the cylinder head, near the thermostat housing. Look for 'G4LA' or 'G4LC' for the 1.2L or 1.4L variants.

Engine code locations per Hyundai Motor Company Service Manual – Vehicle Identification. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7.

Hyundai Engine Technology Specifications and Reliability Data

A technical breakdown of Hyundai's core engine systems including CVVT, T-GDI turbocharging, timing architectures and modular design with documented reliability impacts. All data sourced from Hyundai Motor Company Service Manual, Hyundai TSI and EU Regulation (EC) No 715/2007

Overview

Hyundai's CVVT (Continuous Variable Valve Timing) system continuously adjusts intake camshaft timing to optimize performance, fuel economy, and emissions across the rev range.

How it Works

An oil-controlled phaser on the camshaft adjusts timing based on engine speed and load. Dual CVVT systems adjust both intake and exhaust camshafts for maximum efficiency.

Engine Code FAQ Common Questions Answered

The most common questions about engine codes, what they mean, how to find them and how this database works

Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.

No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.

No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
