The Chrysler ECC is a 3,300 cc, 60° V6 petrol engine produced between 1993 and 1995. It features sequential multi — port fuel injection, cast — iron block construction, and an overhead valve (OHV) valvetrain. This engine was designed as a robust, torque — oriented powerplant for Chrysler's full — size vans and trucks, delivering 150 hp (112 kW) and 215 lb‑ft (291 Nm) of torque.
Fitted primarily to the B — van platform, including the Dodge Ram Van and Plymouth Voyager, the ECC was…

Production years 1993–1995 meet US Federal Tier 0 emissions standards (EPA Certificate of Conformity #A-93-03).
The Chrysler ECC is a 3,300 cc 60° V6 petrol engine engineered for full-size vans and light trucks (1993-1995). It combines sequential multi-port fuel injection with a cast-iron block to deliver strong low-end torque and proven durability. Designed to meet US Federal Tier 0 emissions standards, it prioritizes reliability for commercial and fleet use.

The Chrysler ECC was used across Chrysler Corporation's B-van platform with longitudinal mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-primarily related to accessory drive layouts and exhaust routing for different van body styles. All adaptations are documented in OEM technical bulletins.
The ECC's primary long-term reliability consideration is cooling system maintenance. Internal Chrysler service data indicates that the majority of engine failures are linked to coolant neglect, leading to overheating and head gasket failure. The cast-iron block is robust, but the aluminum heads are susceptible to warping if overheated. Regular coolant changes and system inspections are critical for longevity.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the ECC is known for its robust, simple design and potential for high mileage. Its cast-iron block and gear-driven camshaft are very durable. Long-term reliability is heavily dependent on meticulous cooling system maintenance to prevent head gasket failure. With proper care, these engines can easily exceed 200,000 miles.
The most frequent issues are cooling system failures leading to overheating, intake manifold vacuum leaks on early models, distributor cap/rotor wear causing misfires, and exhaust manifold stud breakage. These are well-documented in Chrysler service bulletins and repair manuals.
The 3.3L ECC engine was used in the Dodge Ram Van/Wagon (B150/B250), Plymouth Voyager, and Chrysler Town & Country minivans from the 1993 to 1995 model years. It was the standard or optional V6 for these full-size van platforms during that period.
Significant power gains are difficult due to its low-compression, OHV design. Basic modifications like a cold air intake and free-flowing exhaust might yield minor improvements. More aggressive tuning is generally not cost-effective or reliable for this engine, as it was designed for torque and durability, not high performance.
Fuel economy is modest, typical for a heavy vehicle with a large displacement, low-compression V6 from that era. Expect around 14-16 mpg (US) in city driving and 18-20 mpg (US) on the highway in a full-size van. Minivans equipped with the ECC may see slightly better figures, around 16-18 mpg city and 20-22 mpg highway.
No. The Chrysler ECC is a non-interference engine. This means that if the timing chain (which drives the distributor and oil pump, not the valves) were to fail, or if the valves were to stop moving, the pistons would not contact the valves. This design prevents catastrophic internal engine damage from timing component failure.
Chrysler recommended API SH 10W-30 motor oil for normal operating conditions. For colder climates, 5W-30 was specified. Modern equivalents meeting API SN or SP standards in the same viscosity grades (10W-30 or 5W-30) are perfectly suitable and provide better protection. Regular oil changes are essential.
