The Dodge EKG is a 3,598 cc, V6 gasoline engine produced between 2015 and 2020. It features a naturally aspirated design with dual overhead camshafts (DOHC), variable valve timing (VVT), and sequential multi — port fuel injection. Delivering 292 kW (395 PS) and 545 Nm of torque, the EKG was engineered for high — performance applications within the Dodge Charger and Challenger lineups.

Production years 2015–2020 meet U.S. EPA Tier 2 Bin 5 and Euro 6 standards . High-performance tuning requires premium unleaded fuel (91+ AKI).
The Dodge EKG is a 3,598 cc V6 gasoline engine engineered for high-performance sedans and coupes (2015–2020). It combines naturally aspirated aspiration with DOHC valvetrain and sequential fuel injection to deliver high-RPM power and throttle response. Designed to meet stringent emissions standards, it balances performance with regulatory compliance.

The Dodge EKG was used across Dodge's Charger and Challenger platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Charger and shorter accessory drives in the Challenger-and from 2018 the updated casting process introduced improved thermal management, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The EKG's primary reliability risk is exhaust manifold cracking under sustained high-load use, with elevated incidence in track-driven vehicles. Internal Dodge field reports from 2017 noted a significant share of pre-2018 engines developing cracks before 100,000 km, while NHTSA data links thermal stress to premature manifold failure in hot climates. Aggressive driving and poor cooling maintenance increase thermal fatigue, making inspection and coolant system integrity critical.
Analysis derived from Dodge technical bulletins (2015-2020) and NHTSA failure statistics (2016-2021). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The EKG offers strong high-RPM performance and mechanical durability, but pre-2018 models are prone to exhaust manifold cracking under track use. Later revisions (2018+) improved casting integrity and thermal management. Regular maintenance, strict oil changes (15,000 km max), and use of premium fuel (91+ AKI) significantly improve long-term reliability.
Key issues include exhaust manifold cracking (especially pre-2018), timing chain tensioner wear, intake/EGR carbon buildup, and valve stem seal leakage. These are documented in Dodge SIB 09-003-18 and field service reports. Thermal management and maintenance intervals are critical factors.
The EKG was used in the Dodge Charger SRT Hellcat (2015–2020) and Challenger SRT Hellcat (2015–2020) in North American and select international markets. It was not offered in supercharged trims. All variants produce 395 PS and are longitudinally mounted with model-specific calibration.
Aftermarket ECU tuning is common on the EKG platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Dodge Charger SRT Hellcat, real-world consumption averages ~14.7 L/100km (19 mpg US) in mixed driving. City driving can exceed 18 L/100km (13 mpg US), while highway runs achieve ~11.2 L/100km (21 mpg US). Expect 13–19 mpg US depending on driving conditions and throttle input.
Yes, the EKG is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. The front-mounted chain is robust, but any signs of rattle or oil starvation should be investigated immediately to prevent catastrophic failure.
Dodge specifies Mopar SAE 5W-20 synthetic oil meeting MS-6395 standard. This formulation ensures proper valvetrain lubrication and thermal stability. Oil changes must not exceed 15,000 km or 12 months. Using non-compliant oil can accelerate timing wear and void warranty coverage.
