The Dodge EZB is a 3,604 cc, V6 gasoline engine produced between 2011 and 2015. It features a dual overhead cam (DOHC) valvetrain with variable valve timing (VVT) and sequential multi — port fuel injection. Delivering 239 kW (321 PS) and 363 Nm of torque, it was engineered for responsive acceleration and mid — range power delivery in mainstream sedans and crossovers.
Fitted to models such as the Dodge Avenger, Chrysler 200, and Jeep Liberty, the EZB was designed to balance per…
All production years 2011–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The Dodge EZB is a 3,604 cc V6 DOHC engine engineered for mid-size sedans and crossovers (2011-2015). It combines sequential multi-port fuel injection with dual overhead camshafts and variable valve timing to deliver balanced performance and drivability. Designed to meet Euro 5 standards, it offers a blend of responsiveness and efficiency for everyday driving.

The Dodge EZB was used across Dodge's Avenger/Chrysler 200 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-reinforced engine mounts in the Chrysler 200 and revised intake manifolds in the Dodge Avenger-and from 2013 the facelifted Jeep Liberty adopted updated chain guides, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The EZB's primary reliability risk is timing chain guide wear on early builds, with elevated incidence in urban driving. Internal Dodge quality reports from 2013 indicated a notable share of pre-2013 engines requiring guide replacement before 100,000 km, while UK DVSA records link a significant portion of drivability complaints to intake manifold carbon buildup in high-mileage units. Short-trip cycles and extended idling increase guide and valve train stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The EZB delivers smooth performance and adequate efficiency, but early models (2011-2012) had reliability concerns, especially timing chain guide wear. Later revisions (post-2013) improved durability with updated guides and oil pumps, so well-maintained examples can be robust. Regular servicing and using high-quality oil (5W-20 MS-6395) greatly aid longevity.
The biggest issues are timing chain guide wear (leading to rattling noises and power loss), intake carbon buildup affecting throttle response, and ignition coil failures. Other complaints include oil leaks from gaskets and occasional PCV system clogs. These are well-documented in Dodge service bulletins.
This 3.6L V6 was used in several Dodge and Chrysler mid-size vehicles. It appeared in the Dodge Avenger, Chrysler 200, and Jeep Liberty between 2011 and 2015. No cross-manufacturer usage is documented for this engine variant.
Yes. The EZB responds well to tuning. ECU remaps can safely gain +15-25 kW on stage 1, as the stock internals handle increased torque. Aftermarket upgrades (cold air intake, exhaust, camshafts) can boost power further. Enthusiasts frequently modify Avenger and 200 models for improved responsiveness. Tuning should be done carefully with supporting modifications.
Moderate for a naturally aspirated V6. In a Chrysler 200 (239 kW version), typical consumption is ~11.0 L/100km (city) and ~7.2 L/100km (highway), or about 25.7 mpg UK combined. Real-world figures depend heavily on driving style, but expect 22-26 mpg (UK) on mixed roads for a healthy EZB.
Yes. The EZB is an interference engine. This means if the timing chain fails, the pistons may contact the valves, potentially causing catastrophic internal damage. Immediate repair is required upon any sign of chain or guide failure to prevent major engine damage.
Dodge specifies a 5W-20 synthetic oil meeting MS-6395 specification. Always use a quality oil designed for high-performance gasoline engines and change it every 15,000 km or as recommended to ensure proper timing system lubrication and minimize wear.
