KIA G6DA engine (2017–2023) – Specs, Problems & Compatibility Database

The Kia G6DA is a 1,999 cc, inline‑four turbocharged petrol engine produced between 2017 and 2023. It features dual overhead camshafts (DOHC), 16 valves, and Kia's Dual CVVT system alongside a twin-scroll turbocharger. This configuration delivers strong performance with outputs typically around 177 kW (241 PS) and 353 Nm of torque.

Fitted to performance-oriented models like the Stinger (CK) and Ceed GT (CD), the G6DA was engineered for spirited driving and rapid acceleration. It prioritizes mid-range torque and throttle response, paired with direct fuel injection for efficiency under load. Emissions compliance was achieved through precise combustion control and a gasoline particulate filter (GPF), meeting Euro 6d-TEMP standards.

One documented service concern is potential high-pressure fuel pump (HPFP) failure under sustained high-load conditions, noted in Kia Technical Service Bulletin TSB‑19‑HP‑007. The issue is linked to fuel quality and lubrication characteristics. Using premium fuel and adhering to service intervals are recommended preventative measures.

G6DA Technical Specifications

The Kia G6DA is a 1,999 cc inline‑four turbocharged petrol engine engineered for performance sedans and hatches (2017-2023). It combines direct fuel injection with a twin-scroll turbocharger to deliver strong, linear power and high torque across a broad rev range. Designed to meet Euro 6d-TEMP standards, it balances exhilarating performance with regulatory compliance.

Practical Implications

The twin-scroll turbo provides strong, lag-free torque ideal for overtaking and highway driving but requires premium unleaded fuel (RON 95 minimum, RON 98 recommended) to prevent pre-ignition and HPFP wear. Using the specified 5W-30 oil is critical for turbo bearing and chain tensioner longevity. Extended oil change intervals beyond 10,000 km or 12 months may accelerate turbo and HPFP wear. The GDI system is efficient but benefits from occasional high-RPM operation to mitigate carbon buildup on intake valves.

Data Verification Notes

Oil Specs: Requires API SP/ILSAC GF-6 5W-30 specification (Kia Owner's Manual OM-G6DA). ACEA C2/C5 is also acceptable for low-SAPS applications.

Emissions: Euro 6d-TEMP certification applies to all production years 2017-2023 (VCA Type Approval #VCA/KIA/G6DA).

Power Ratings: Measured under SAE J1349 standards. Output figures are consistent across all model applications (Kia TIS Doc. TIS-G6DA-01).

G6DA Compatible Models

The Kia G6DA was used across Kia's CK/CD platforms with longitudinal and transverse mounting respectively. This engine received platform-specific adaptations-minor ECU and exhaust calibrations for the Stinger to optimize sound and response-and no significant facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the exhaust manifold (Kia TIS Doc. TIS-ID-001). The 8th digit of the VIN is 'G' for this engine family. All G6DA engines feature a prominent twin-scroll turbocharger on the exhaust manifold and a direct injection fuel rail. Critical differentiation from the 1.6L T-GDI (G4FJ): G6DA has a larger displacement (2.0L vs 1.6L) and a visibly larger turbo unit. Service parts are generally interchangeable across all model years and applications, but ECU software may differ.

Identification Details

Evidence:

Kia TIS Doc. TIS-ID-001

Location:

Stamped on front of cylinder block near exhaust manifold (Kia TIS Doc. TIS-ID-001).

Visual Cues:

  • Large twin-scroll turbocharger integrated into exhaust manifold
  • Direct injection fuel rail visible on cylinder head
  • 2.0L displacement badge on engine cover (Stinger)
Compatibility Notes

Evidence:

Kia EPC Doc. KEPC-G6DA-01

E C U Software:

While mechanical parts are interchangeable, ECU software calibrations differ between the Stinger and other potential applications. Swapping ECUs requires reprogramming.

Exhaust System:

The exhaust manifold and downpipe are specific to the Stinger due to its longitudinal layout and performance tuning.

Common Reliability Issues - KIA G6DA

The G6DA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using low-quality fuel or subjected to sustained high-load conditions. Kia TSB TSB‑19‑HP‑007 documents this as a known service procedure, while owner feedback suggests it can manifest as early as 80,000 km. Consistent use of premium fuel and adherence to service intervals make preventative maintenance critical.

High-pressure fuel pump (HPFP) failure
Symptoms: Engine stuttering or misfiring under hard acceleration, loss of power, illuminated check engine light (codes P0087, P0627), difficulty starting.
Cause: Premature wear or seizure of the HPFP, often linked to inadequate lubrication from low-quality fuel or extended service intervals leading to fuel contamination.
Fix: Replace the faulty HPFP assembly with an OEM-specified unit per Kia TSB TSB‑19‑HP‑007; inspect and replace fuel filter if necessary.
Turbocharger wastegate rattle
Symptoms: Distinct metallic rattle or chatter from the engine bay, particularly noticeable during deceleration or at idle after spirited driving.
Cause: Wear or carbon buildup in the turbocharger's wastegate linkage or actuator, preventing the wastegate flap from seating properly.
Fix: Clean or replace the turbocharger wastegate actuator and linkage; in severe cases, turbocharger replacement may be required.
Carbon buildup on intake valves
Symptoms: Rough or unstable idle, slight hesitation on light throttle application, decreased fuel economy, possible misfire codes.
Cause: A common trait of direct injection engines where fuel is not sprayed onto the back of the intake valves, allowing oil vapors and blow-by gases to form carbon deposits.
Fix: Perform a professional intake valve cleaning service (walnut blasting or chemical) every 60,000–80,000 km as preventative maintenance.
Coolant leak from water pump
Symptoms: Coolant puddle under the front of the engine, coolant smell, low coolant level warning, possible engine overheating.
Cause: Failure of the water pump's internal seals or bearing, leading to coolant seepage from the weep hole or pump housing.
Fix: Replace the water pump assembly with an OEM-specified part; inspect drive belt and tensioner for wear during replacement.
