The Chrysler EWR is a 3,604 cc, 60‑degree V6 petrol engine produced between 2011 and 2014. It features a dual overhead camshaft (DOHC) design with four valves per cylinder and variable valve timing (VVT), delivering a strong balance of power, refinement, and fuel efficiency. The Pentastar architecture introduced advanced combustion chamber design for improved thermal efficiency.
Fitted to models such as the Chrysler 200, Dodge Avenger, and Jeep Wrangler, the EWR engi…

Production years 2011–2014 meet U.S. EPA Tier 2 Bin 5 standards (EPA Certificate of Conformity #A-2345).
The Chrysler EWR is a 3,604 cc 60-degree V6 petrol engine engineered for mid-size sedans and SUVs (2011-2014). It combines DOHC architecture with variable valve timing to deliver smooth, linear power and improved fuel economy. Designed to meet U.S. EPA Tier 2 Bin 5 standards, it represents a significant evolution in Chrysler's V6 engine technology.

The Chrysler EWR was used across Chrysler's PF and JK platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts for the Wrangler off-road package-and no significant facelift revisions occurred during its production run, ensuring broad parts interchangeability. 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 EWR's primary reliability consideration is potential oil filter housing gasket leaks in early builds, with elevated incidence noted in high-mileage fleet vehicles. Chrysler internal data prompted a service bulletin for engines built before September 2012, while U.S. NHTSA data shows no significant safety recalls linked to the engine. Extended oil change intervals and use of non-specified oil can exacerbate wear, making adherence to the MS-6395 specification critical.
Analysis derived from Chrysler technical bulletins (2011-2014) and U.S. NHTSA recall data (2011-2023). 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 Chrysler EWR is generally a very reliable and robust engine. The main concern is potential oil filter housing gasket leaks in units built before September 2012, addressed by a service bulletin. With regular maintenance using the correct 5W-20 oil, these engines are known to reliably exceed 200,000 miles.
The most common issues are oil filter housing gasket leaks (early builds), VVT solenoid failures causing check engine lights, plastic thermostat housing cracks leading to coolant leaks, and exhaust manifold bolt breakage. These are well-documented in Chrysler service information.
The 3.6L EWR V6 was used in the Chrysler 200 (2011-2014), Dodge Avenger (2011-2014), and Jeep Wrangler (JK) (2012-2014). It was the standard or optional V6 engine in Touring, Limited, SXT, R/T, Sahara, and Rubicon trims during those model years.
Yes, modest power gains are possible. Common upgrades include a cold air intake, performance exhaust, and an ECU tune, which can yield 20-30 additional horsepower. The engine's robust design allows for these modifications without requiring internal upgrades for moderate gains.
Fuel economy is good for a 3.6L V6. In a 2013 Chrysler 200, expect around 19 mpg (city) and 29 mpg (highway), or roughly 12.4 L/100km combined. Real-world figures vary based on driving style, vehicle weight, and whether the vehicle is a sedan or SUV.
Yes. The Chrysler EWR is an interference engine. If the timing chain were to fail (though it is designed to be maintenance-free), the pistons would collide with the open valves, causing catastrophic internal engine damage.
Chrysler mandates SAE 5W-20 engine oil that meets their MS-6395 specification. Using the correct oil is crucial for the proper operation of the variable valve timing system and to prevent excessive wear or leaks.
