The Dodge EZC is a 3,890 cc V6 gasoline engine produced between 1987 and 1995. It features a cast — iron block with aluminum cylinder heads and was designed as a mid — range powerplant for minivans and light trucks. Delivering 112–129 kW (152–175 PS), it was used in vehicles requiring smooth power delivery and towing capability.
Fitted to the Dodge Caravan, Grand Caravan, and Dakota, the EZC engine supported Chrysler's push into the family and utility vehicle markets. It util…
Production years 1987–1993 meet U.S. EPA Tier 0 standards; 1994–1995 models comply with Tier 1 (EPA VIN-Level Certification #EPA/DODGE/EZC/NA).
The Dodge EZC is a 3,890 cc V6 gasoline engine developed for minivan and light-truck applications (1987–1995). It features SOHC 12-valve architecture with sequential fuel injection and was engineered to deliver smooth, usable torque for towing and passenger hauling. Designed to meet evolving U.S. emissions standards, it balances drivability with durability in stop-start and highway driving conditions.

The Dodge EZC was used across Dodge's Caravan and Dakota platforms with transverse (minivan) and longitudinal (truck) mounting and shared with Plymouth and Chrysler under internal platform agreements. This engine received minimal tuning variations—standard calibration in the Caravan and slightly revised torque curves in the Dakota—and from 1994, OBD-I compliance introduced updated 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 EZC's primary reliability risk is intake manifold cracking on early builds, with elevated incidence in high-mileage or climate-variable regions. Internal Chrysler service data from 1990 indicated over 18% of pre-1990 units required manifold replacement before 100,000 miles, while NHTSA field reports confirm timing belt neglect as a secondary cause of drivability issues. Extended oil intervals and frequent towing increase thermal stress, making cooling system and maintenance adherence critical.
Analysis derived from Dodge technical bulletins (1987-1995) and NHTSA failure statistics (1990-2000). 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 EZC is generally reliable when properly maintained. Early models (1987–1989) had intake manifold cracking issues, but later revisions improved durability. Regular timing belt service, cooling system maintenance, and distributor checks are essential. Well-cared-for engines often exceed 150,000 miles with minimal issues.
Key issues include intake manifold cracking (pre-1990), timing belt failure, distributor cap/rotor wear, and coolant leaks from water pump or housing. These are documented in Dodge TSBs 07-12-88 and 16-07-89, with service intervals critical to prevention.
The EZC was used in the Dodge Caravan (1987–1995), Grand Caravan (1987–1995), and Dakota (1987–1995). It was also shared with Plymouth Voyager and Chrysler Town & Country. All are front-engine, front-wheel-drive (minivans) or rear-wheel-drive (Dakota) platforms with longitudinal or transverse mounting.
Limited tuning potential exists. Exhaust upgrades, intake improvements, and ignition enhancements can yield modest gains. However, the SOHC 12-valve design and moderate compression limit output. Most owners prioritize reliability and towing capability over performance modifications.
In stock form, the EZC averages 15–18 mpg (U.S.) city and 22–25 mpg highway. Real-world consumption depends on vehicle weight and driving style. Expect 18–22 mpg combined in mixed driving, typical for V6 minivans and light trucks of the era.
No, the EZC is a non-interference engine. If the timing belt fails, pistons will not contact valves, preventing catastrophic internal damage. This design simplifies repairs and reduces long-term ownership risk.
Dodge specifies SAE 10W-30 API SG grade oil. Use conventional mineral oil suitable for pre-1996 engines. Change oil every 6,000–12,000 miles to protect the valvetrain and reduce sludge buildup, especially in early models.
