The Chrysler EJG is a 2,499 cc, inline‑four petrol engine produced between 1993 and 1995. It features a cast iron block, aluminum head, and dual overhead camshafts (DOHC) with 16 valves. This engine was designed as a mid — range output variant, delivering 136 hp (101 kW) and 157 lb‑ft (213 Nm) of torque, offering a balance of efficiency and adequate performance for its vehicle class.

Production years 1993–1995 meet US Federal Tier 0 emissions standards (EPA Engine Family Number: CCAE2.5L94A).
The Chrysler EJG is a 2,499 cc inline‑four petrol engine engineered for mid-size sedans (1993-1995). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver smooth, reliable power for daily commuting. Designed to meet early 1990s US Federal emissions standards, it prioritized drivability and cost-effectiveness over peak performance.

The Chrysler EJG was used exclusively in Chrysler Corporation mid-size sedans with longitudinal mounting. This engine was the standard 2.5L DOHC variant for the Dodge Spirit and Chrysler LeBaron, featuring unique ECU tuning compared to the base 2.5L SOHC. No licensing partnerships or platform sharing occurred outside these models. All specifications are documented in OEM service literature.
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 EJG's primary reliability risk is distributor drive gear failure, with elevated incidence in high-mileage applications. Chrysler TSB 18-05-94 documents this as a common cause of ignition failure across the 2.5L DOHC family. Neglecting the 60,000-mile timing belt interval poses a severe risk of total engine destruction due to its interference design, making adherence to this schedule critical.
Analysis derived from Chrysler technical service bulletins (1993-1995) and owner-reported data from the Chrysler Historical Society. 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 EJG can be reliable long-term if its two critical weaknesses are addressed: replacing the distributor gear with the steel update and strictly adhering to the 60,000-mile timing belt interval. With these items maintained, the engine's robust cast iron block and proven design offer good longevity for daily driving.
The most common and critical problems are distributor drive gear wear (TSB 18-05-94) and timing belt failure. Secondary issues include intake manifold gasket leaks and oil leaks from the valve cover or rear main seal. Addressing the first two is paramount for reliability.
The EJG engine was used in the Dodge Spirit (1993-1995) and the Chrysler LeBaron (1993-1995). It was the standard 2.5L DOHC engine for these models, positioned below the higher-performance EER variant.
Yes, mildly. The EJG responds to intake and exhaust upgrades, which can yield modest gains. Its ECU is not easily remappable by modern standards. Significant power increases are limited by the stock internals and the distributor ignition system. Focus is often on improving reliability first.
Fuel economy is reasonable for its era. Expect approximately 20-22 mpg (US) in city driving and 28-30 mpg (US) on the highway in a Dodge Spirit. Real-world figures vary based on driving style and transmission type (manual vs automatic).
Yes. The Chrysler EJG is definitively an interference engine. If the timing belt fails or jumps time, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes the 60,000-mile belt change non-negotiable.
The factory specification is API SH 10W-30 or 5W-30 motor oil. Modern, high-quality synthetic or conventional oils meeting API SP or SN specifications are fully backward compatible and recommended for better protection, especially in older engines.
