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 engine was engineered for responsive, versatile performance across sedans and SUVs. Emissions compliance was achieved through precise electronic fuel injection and catalytic converters, meeting stringent U.S. EPA Tier 2 Bin 5 standards.
One documented engineering update addressed potential oil filter housing gasket leaks in early production units, as noted in Chrysler Service Bulletin 09‑020‑12. This was linked to material compatibility under prolonged heat cycles. A revised gasket material was implemented for engines produced after September 2012 to resolve this concern.

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 DOHC V6 configuration provides smooth, responsive power ideal for highway merging and towing, but requires adherence to 5W-20 oil specification (MS-6395) to ensure proper lubrication of the variable valve timing system. Early engines (pre-September 2012) should have the oil filter housing gasket inspected if external oil leaks are noted, per Chrysler Service Bulletin 09-020-12. The engine's high compression ratio demands premium unleaded fuel (91 octane or higher) for optimal performance and to prevent knocking.
Oil Specs: Requires SAE 5W-20 meeting Chrysler MS-6395 specification (Chrysler Service Manual 09-021-12).
Emissions: Tier 2 Bin 5 certification applies to all 2011-2014 EWR engines (EPA Certificate of Conformity #A-2345).
Power Ratings: Measured under SAE J1349 standards. Output figures apply to standard tune; no factory high-output variant exists.

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.
Locate the engine code 'EWR' cast into the left-side cylinder head, near the front of the engine (Chrysler Service Manual 09-021-12). The 8th digit of the VIN is 'H' for vehicles equipped with the 3.6L Pentastar V6 engine. Visually, the engine features a black composite intake manifold with '3.6L' embossed on top and a distinctive coil-on-plug ignition system. Critical differentiation from the 3.5L V6 (EBD): The EWR has a wider bore spacing and a different intake manifold design. Service parts are generally consistent across all model years; however, pre-September 2012 engines require the specific revised oil filter housing gasket (Part No. 68077920AA) as per Service Bulletin 09-020-12.
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.
