The Dodge ENR is a 3,605 cc, V6 gasoline engine produced between 2007 and 2011. It features dual overhead camshafts (DOHC), variable valve timing (VVT), and sequential fuel injection. Designed for light — duty truck and SUV applications, it delivered 210 kW (285 PS) and 353 Nm of torque, providing a balance of daily drivability and towing capability.
Fitted to models such as the Dodge Ram 1500 and Dodge Challenger (early concept phase), the ENR engine was engineered for resp…
Production years 2007–2009 meet U.S. EPA Tier 2 Bin 5; 2010–2011 models comply with Euro 4 standards in export markets (EU Regulation (EC) No 715/2007).
The Dodge ENR is a 3,605 cc V6 gasoline engine engineered for light-duty trucks and SUVs (2007–2011). It combines DOHC architecture with variable valve timing to deliver responsive mid-range power and smooth operation. Designed to meet U.S. EPA Tier 2 and Euro 4 emissions standards, it balances performance with regulated efficiency.

The Dodge ENR was used across Dodge's Ram and Challenger platforms with longitudinal mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Ram 1500 and revised cooling in the Challenger-and from 2010, the updated Ram models adopted revised cam phasers, 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Dodge technical bulletins (2008-2012) and U.S. NHTSA failure statistics (2010-2015). 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 ENR delivers solid performance and efficiency, but early models (2007-2009) had reliability concerns, particularly cam phaser wear. Later revisions (post-2010) improved phaser durability, 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 camshaft phaser wear (leading to rattling or timing faults), intake carbon buildup, coolant leaks from thermostat housing, and ignition coil failures. These are well-documented in Dodge service bulletins and NHTSA filings.
The ENR was primarily used in the Dodge Ram 1500 (2007-2011) across ST, SLT, and Laramie trims. It also appeared in pre-production Dodge Challenger prototypes (2008-2009). No passenger car applications reached full production.
Aftermarket ECU tuning is common on the ENR 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 Ram 1500, typical consumption is ~14.7 L/100km (city) and ~9.8 L/100km (highway), or about 19 mpg UK combined. Real-world figures vary by load and driving style, but expect 17-21 mpg (UK) on mixed roads for a healthy ENR.
Yes. The ENR is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic internal damage. Timing system maintenance is critical—any unusual noise should be investigated immediately.
Dodge specifies SAE 5W-20 synthetic oil meeting MS-6395 specification. Use a quality oil designed for modern gasoline engines and change it every 10,000 km to ensure proper phaser lubrication and minimize deposits.
