The Chrysler ESD is a 2,429 cc, inline‑four petrol engine produced between 2001 and 2004. It features a dual overhead camshaft (DOHC) design with four valves per cylinder and sequential fuel injection, delivering responsive performance for compact sedans. An aluminum block and head provide a favorable power — to — weight ratio.

Production years 2001–2004 meet U.S. EPA Tier 2 Bin 5 standards (EPA Certificate of Conformity #A-3456).
The Chrysler ESD is a 2,429 cc inline-four petrol engine engineered for compact sedans (2001-2004). It combines DOHC architecture with sequential fuel injection to deliver responsive, linear power for agile driving. Designed to meet U.S. EPA Tier 2 Bin 5 standards, it balances performance with regulatory compliance.

The Chrysler ESD 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 ESD's primary reliability consideration is potential oil consumption in early builds, with elevated incidence noted in high-mileage fleet vehicles. Chrysler internal data prompted a service bulletin for engines built before January 2003, while U.S. NHTSA data shows no significant safety recalls linked to the engine. The timing belt is a critical wear item; failure results in severe engine damage, making strict adherence to the replacement schedule paramount.
Analysis derived from Chrysler technical bulletins (2001-2004) and U.S. NHTSA recall data (2001-2023). 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 ESD can be reliable long-term with meticulous maintenance. Its main concerns are potential oil consumption in pre-January 2003 builds (addressed by a service bulletin) and the critical need to replace the timing belt at the recommended interval. With these addressed and regular oil changes using the correct 5W-30 oil, these engines can reliably reach 150,000+ miles.
The most common issues are excessive oil consumption (early builds), timing belt failure if not replaced on schedule, oil leaks from the valve cover or camshaft seals, and coolant leaks from the water pump. These are well-documented in Chrysler service information and are generally straightforward to repair if caught early.
The 2.4L DOHC ESD engine was used in the Chrysler Sebring (2001-2004), Dodge Stratus (2001-2004), and Plymouth Breeze (2001-2002). It was typically the higher-performance engine option in LX, Touring, SE, and ES trims during those model years.
Yes, the ESD responds well to basic modifications. Common upgrades include a cold air intake, performance exhaust, and an ECU tune, which can yield 10-20 additional horsepower. More significant power gains are possible with forced induction, but this requires substantial supporting modifications and is not common for stock engines.
Fuel economy is reasonable for a 2.4L DOHC engine of its era. In a 2003 Dodge Stratus, expect around 20 mpg (city) and 28 mpg (highway), or roughly 12.4 L/100km combined. Real-world figures vary based on driving style, vehicle condition, and maintenance history.
Yes. The Chrysler ESD is an interference engine. If the timing belt 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. This makes the timing belt replacement schedule critically important.
Chrysler mandates SAE 5W-30 engine oil that meets their MS-6395 specification. Using the correct oil is essential for protecting the hydraulic lifters and ensuring the longevity of the engine. Extended oil change intervals should be avoided.
