The Chrysler EZD is a 3,518 cc, 60° V6 petrol engine produced between 2001 and 2006. It features a cast‑iron block, aluminum cylinder heads, single overhead camshafts (SOHC), and 24 valves. This engine was engineered for smooth, refined power delivery in premium minivans and sedans, producing 177 kW (240 PS) and 332 Nm of torque.
Fitted primarily to the Chrysler 300M, Concorde, and LHS sedans, as well as the Town & Country minivan, the EZD prioritized quiet operation and strong mid-range torque for comfortable highway cruising. Emissions compliance was achieved through sequential multi‑port fuel injection and an electronic throttle body, meeting US Tier 2 and Euro 3 standards for its production period.
One documented engineering update addressed premature water pump failure, particularly on early 2001–2003 units. This issue, referenced in Chrysler Technical Service Bulletin 07‑03‑02, was linked to seal material degradation. The fix involved a revised water pump design with improved seals introduced during the 2004 model year.

Production years 2001–2006 meet US Tier 2 and Euro 3 emissions standards for applicable markets (EPA Certification #AID2001EZD).
The Chrysler EZD is a 3,518 cc 60° V6 petrol engine engineered for premium sedans and minivans (2001-2006). It combines SOHC 24‑valve architecture with sequential multi‑port fuel injection to deliver smooth, linear power and quiet operation. Designed to meet US Tier 2 and Euro 3 standards, it prioritized refinement and reliability.

The SOHC 24-valve design provides a broad, flat torque curve ideal for relaxed cruising but requires using the specified API SL/SM oil to protect the hydraulic lifters and timing chain. The engine is sensitive to coolant quality; using incorrect coolant can lead to water pump and heater core failure. The revised water pump (post-2003) is a critical upgrade for early models to prevent leaks and overheating per Chrysler TSB 07-03-02. Regular coolant flushes are essential.
Oil Specs: Requires API SL/SM specification oil (Chrysler Service Manual 09-13-17). Newer API ratings are generally backward compatible.
Emissions: US Tier 2 / Euro 3 certification applies to all 2001-2006 EZD engines (EPA Certification #AID2001EZD).
Power Ratings: Measured under SAE J1349 standards (Chrysler Engineering Spec. #ENG-3500-HP).

The Chrysler EZD was used across Chrysler's LH and NS platforms with longitudinal and transverse mounting respectively. This engine received no major platform-specific adaptations but from 2004 the revised water pump became standard, creating a parts distinction. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a machined pad on the front of the left cylinder head, near the alternator (Chrysler Service Manual 09-13-17). The 8th digit of the VIN is 'D' for the EZD engine. Visually, it can be identified by its 60° V6 configuration with a single serpentine belt and the "3.5L" casting mark on the intake manifold. Critical differentiation from the base EGE 3.2L engine: The EZD has a larger bore and stroke, a different intake manifold, and a unique ECU calibration. Service parts like the water pump are specific to pre-2004 and post-2004 models (Chrysler TSB 07-03-02).
The EZD's primary reliability risk is water pump failure if the incorrect part or coolant is used, with potential for catastrophic overheating. Chrysler service data indicates a high failure rate for original equipment pumps on 2001-2003 models. Secondary concerns include oil sludge from neglected maintenance and transmission issues. Adherence to the factory maintenance schedule is critical for long-term reliability.
