The Chrysler ENC is a 2,736 cc, 60‑degree V6 petrol engine produced between 2002 and 2006. It features a single overhead camshaft (SOHC) design with four valves per cylinder and sequential fuel injection, delivering smooth, adequate power for mid — size sedans. A cast — iron block and aluminum heads provide a balance of durability and weight.
Fitted to models such as the Chrysler Sebring, Dodge Stratus, and Chrysler Cirrus, the ENC engine was engineered for quiet, refined o…

Production years 2002–2006 meet U.S. EPA Tier 2 Bin 5 standards (EPA Certificate of Conformity #A-9012).
The Chrysler ENC is a 2,736 cc 60-degree V6 petrol engine engineered for mid-size sedans (2002-2006). It combines SOHC architecture with sequential fuel injection to deliver smooth, linear power for daily driving. Designed to meet U.S. EPA Tier 2 Bin 5 standards, it prioritizes refinement and ease of maintenance over high performance.

The Chrysler ENC was used across Chrysler's JA platform with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production run, ensuring broad parts interchangeability. All applications 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 ENC's primary reliability consideration is potential oil sludge formation under severe service conditions, with elevated incidence noted in vehicles subjected to frequent short trips and infrequent oil changes. Chrysler internal data prompted a service bulletin reinforcing maintenance procedures, while U.S. NHTSA data shows no significant safety recalls linked to the engine. Adherence to the MS-6395 oil specification and recommended change intervals is the most critical factor for long-term health.
Analysis derived from Chrysler technical bulletins (2002-2006) and U.S. NHTSA recall data (2002-2023). 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 ENC can be reliable long-term with meticulous maintenance. Its main vulnerability is oil sludge formation, which can be entirely prevented by using the correct 5W-30 oil and changing it every 5,000 miles, especially if the vehicle is used for short trips. Addressing issues like the timing chain tensioner promptly is also key to longevity.
The most common issues are oil sludge buildup (due to poor maintenance), timing chain tensioner failure causing noise, IMRC actuator/runner faults triggering check engine lights, and coolant leaks from the water pump or crossover tube. These are well-documented in Chrysler service information.
The 2.7L ENC V6 was used in the Chrysler Sebring (2002-2006), Dodge Stratus (2002-2006), and Chrysler Cirrus (2002-2003). It was typically the optional or higher-trim V6 engine in LX, Touring, SE, and SXT variants during those model years.
Significant power gains are not common for the ENC. Its SOHC design prioritizes smoothness over high output. Basic modifications like a cold air intake or cat-back exhaust may yield minor improvements, but the engine's architecture limits its tuning potential compared to DOHC designs.
Fuel economy is average for a 2.7L V6 of its era. In a 2004 Dodge Stratus, expect around 18 mpg (city) and 27 mpg (highway), or roughly 13.8 L/100km combined. Real-world figures vary based on driving style, vehicle condition, and maintenance history.
Yes. The Chrysler ENC is an interference engine. If the timing chain were to fail or jump time, the pistons would collide with the open valves, resulting in severe internal engine damage and requiring a costly rebuild or replacement.
Chrysler mandates SAE 5W-30 engine oil that meets their MS-6395 specification. This is non-negotiable for preventing sludge and ensuring the hydraulic timing chain tensioner operates correctly. Extended oil change intervals should be strictly avoided.
