The Chrysler EZB is a 3,604 cc, 60‑degree V6 petrol engine produced between 2011 and 2017. It features an aluminium block and heads, dual overhead camshafts (DOHC), and variable valve timing (VVT) on both intake and exhaust camshafts. This configuration delivers smooth, responsive power, with outputs typically rated at 213 kW (286 PS) and 353 Nm of torque.
Fitted to the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee, the EZB engine was engineered for a blend of everyd…

Production years 2011–2017 meet Euro 5 standards for applicable markets (VCA UK Type Approval #VCA/EMS/5680).
The Chrysler EZB is a 3,604 cc 60-degree V6 petrol engine engineered for full-size sedans and SUVs (2011-2017). It combines DOHC with dual variable valve timing to deliver strong, linear power and refined operation. Designed to meet Euro 5 standards, it offers a compelling mix of performance and efficiency for its class.

The Chrysler EZB was used across Chrysler's LX and WK2 platforms with longitudinal mounting. This engine received platform-specific adaptations-including unique engine mounts and accessory drive layouts for the 300 versus the Grand Cherokee-but remained largely consistent mechanically. All adaptations are documented in OEM technical bulletins.
The EZB's primary reliability focus is on the variable valve timing (VVT) system and associated oil pressure, with elevated incidence in vehicles subjected to infrequent oil changes. Chrysler internal service data indicates VVT solenoid or phaser issues are a leading cause of check engine lights in high-mileage examples, while oil sludge buildup can exacerbate timing chain tensioner wear. Maintaining strict oil change intervals with the correct specification is critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The EZB is generally robust with strong internals. Its main long-term concerns are the VVT system and timing chain tensioners, which rely heavily on clean oil and correct viscosity. With strict adherence to maintenance schedules using the specified 5W-20 oil, the EZB can easily surpass 200,000 km. Neglecting oil changes is the primary cause of major issues.
The most frequent issues are VVT solenoid/phaser failures causing check engine lights, timing chain tensioner wear leading to noise, intake manifold gasket leaks causing vacuum issues, and ignition coil failures resulting in misfires. These are well-documented in Chrysler service bulletins and repair databases.
The EZB 3.6L V6 was primarily used in the Chrysler 300 (2011-2017), Dodge Charger (2011-2017), and Jeep Grand Cherokee (2011-2017). It was the standard V6 for these platforms during this period, succeeding the earlier EGM variant with minor efficiency updates.
Yes, the EZB responds well to basic bolt-on modifications. A performance intake and exhaust can yield modest gains. More significant power increases require forced induction (supercharger/turbo kit), which is popular but requires supporting modifications (fuel system, ECU tune, cooling) to be reliable. Stock internals are strong but have limits.
Fuel economy is typical for a large, naturally aspirated V6. Expect around 14-16 L/100km (17-20 mpg UK) in city driving and 10-12 L/100km (23-28 mpg UK) on the highway. Combined figures usually land around 12-13 L/100km (21-23 mpg UK), heavily dependent on driving style and vehicle weight.
Yes. The Chrysler EZB is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. This underscores the importance of addressing any timing chain noise promptly.
Chrysler mandates the use of 5W-20 engine oil meeting their MS-6395 specification. This specific viscosity is crucial for the proper operation of the variable valve timing system. Using a heavier oil can cause VVT-related problems and check engine lights. Change intervals should not exceed 10,000 km.
