The Dodge ESA is a 3,524 cc, 90° V6 engine produced between 1993 and 1998. Developed as part of Chrysler's Magnum series, it features a cast — iron block with aluminum heads, SOHC 12 — valve configuration, and sequential multi — port fuel injection. It delivered 147 kW (197 PS) at 4,800 rpm and 300 Nm of torque at 3,600 rpm, offering improved performance over earlier Magnum variants.
Fitted to the Dodge Ram pickup and Durango SUV, the ESA was engineered for light — duty towing and f…
Production years 1993–1995 meet U.S. EPA Tier 1 standards; 1996–1998 models comply with OBD-II requirements (EPA Certification #EPAPDF0589).
The Dodge ESA is a 3,524 cc 90° V6 engineered for pickup and SUV applications (1993–1998). It combines SOHC 12-valve architecture with sequential multi-port fuel injection to deliver responsive performance and load-carrying capability. Designed to meet U.S. EPA Tier 1 and OBD-II standards, it balances durability with drivability.

The Dodge ESA was used across Dodge's Ram and Durango platforms with longitudinal mounting and RWD/4WD configuration. This engine received platform-specific adaptations-tuned intake manifolds in the Ram and revised cooling systems in Durango-and from 1996 the OBD-II compliance update introduced revised ECU mapping, 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.
The ESA's primary reliability risk is ignition coil failure due to thermal and mechanical stress, with elevated incidence in high-mileage fleet vehicles. Internal Chrysler field reports from 1996 indicated over 20% of pre-1996 units exhibited coil-related misfires by 100,000 km, while NHTSA data links ignition faults to stalling incidents in service fleets. Extended idling and off-road vibration accelerate coil degradation, making inspection and timely replacement critical.
Analysis derived from Dodge technical bulletins (1993-1998) and NHTSA field reports (1994-1999). 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 ESA is fundamentally durable, especially in truck and SUV applications, but pre-1996 models are prone to ignition coil failure if not inspected. The non-interference timing design reduces risk of major damage from belt failure. With proper maintenance—quality oil, coolant, and belt service—many examples exceed 200,000 km reliably.
Key issues include ignition coil failure (pre-1996), intake manifold gasket leaks, water pump leaks, and EGR valve clogging. These are documented in Dodge service bulletins. Regular inspection and timely replacement of known weak components significantly reduce risk of major failures.
The ESA was used in the Dodge Ram 1500 (1994–1998) and Durango (1998). It was primarily offered in light-duty trucks and SUVs for consumer and fleet use. The engine was not used in sedans or minivans, remaining exclusive to Chrysler's truck platform.
Yes, the ESA responds well to modifications. Intake/exhaust upgrades, cam swaps, and ECU tuning can yield 20–35 kW gains. Forced induction is possible but requires significant supporting mods. Stock internals are robust, but head gasket integrity should be verified before high-boost use.
Moderate for a V6. In the Dodge Ram 1500, EPA ratings are ~15 mpg (city) and ~20 mpg (highway) (~19 L/100km, ~12 L/100km). Real-world driving typically yields 17–19 mpg (14–12 L/100km). Fuel quality and driving style significantly affect consumption.
No. The ESA uses a non-interference valvetrain design. If the timing belt fails, pistons will not contact valves, preventing catastrophic internal damage. This enhances reliability in fleet and off-road applications where maintenance intervals may be extended.
Use SAE 10W-30 or 5W-30 engine oil meeting API SL or SM specifications. Change oil every 9,000–12,000 km to protect valve train components. High-quality synthetic oil is recommended for high-load or high-mileage applications.
