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.

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 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.
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.
Analysis derived from Chrysler technical bulletins (2001-2006) and NHTSA complaint data (2001-2010). 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 EZD can be very reliable with proper maintenance. Its timing chain is robust. The main threat is the original water pump on early models (2001-2003), which is prone to failure. Replacing it with the revised unit and using the correct coolant are crucial. With these addressed, these engines can easily surpass 250,000 km.
The most critical issue is water pump failure on early builds, leading to overheating. Oil sludge buildup from poor maintenance, ignition coil failures, and associated transmission (42LE) problems are also common. These are well-documented in Chrysler TSBs and owner reports.
The EZD powered Chrysler's premium offerings: the 300M, Concorde, LHS (2001 only), and the upscale Town & Country LXi/Limited minivans from 2001 to 2006. It was the top-tier V6 option, replacing the 3.2L in most applications.
Yes, but gains are modest. A cold air intake and cat-back exhaust can yield 5-10 kW. ECU reflashing is limited. Significant power increases require internal modifications and are not cost-effective. It is better suited to cruising refinement than performance tuning.
Expect around 13.8 L/100km (20 mpg US) in the city and 9.4 L/100km (30 mpg US) on the highway for a 300M or Concorde. Combined, it's approximately 11.8 L/100km (24 mpg US). For the heavier Town & Country, add about 1-2 L/100km. This is typical for a large V6 of its era.
No, the EZD is a non-interference engine. If the timing chain were to fail (which is extremely rare), the pistons will not contact the valves. This is a significant safety feature, meaning a broken chain will simply cause the engine to stop running without internal damage.
Chrysler specifies API SL or SM rated oil, typically SAE 5W-30. Using a high-quality synthetic or semi-synthetic oil that meets this spec is highly recommended to prevent sludge and ensure long engine life, especially given the engine's design.
