The Chrysler EDZ is a 2,429 cc, inline‑four petrol engine produced between 1995 and 2000. It features a cast‑iron block, aluminum cylinder head, dual overhead camshafts (DOHC), and 16 valves. This engine was designed as a higher‑output variant within the Chrysler 2.4 L family, delivering 136 kW (182 PS) and 229 Nm of torque, providing spirited performance for its era.
Fitted primarily to the Dodge Stratus and Chrysler Cirrus sedans, the EDZ was engineered for drivers seeking a balance of mid‑range power and highway cruising refinement over pure economy. Emissions compliance was achieved through sequential multi‑port fuel injection and an electronic throttle body, meeting US Tier 1 and Euro 2 standards for its production period.
One documented engineering update addressed premature exhaust manifold cracking, particularly on early production units. This issue, referenced in Chrysler Technical Service Bulletin 18‑05‑97, was linked to thermal cycling stress. The fix involved a revised manifold casting with improved material and ribbing introduced during the 1998 model year.

Production years 1995–2000 meet US Tier 1 and Euro 2 emissions standards for applicable markets (EPA Certification #AID1995EDZ).
The Chrysler EDZ is a 2,429 cc inline‑four petrol engine engineered for mid‑size sedans (1995-2000). It combines DOHC 16‑valve architecture with sequential multi‑port fuel injection to deliver responsive mid‑range power and smooth operation. Designed to meet US Tier 1 and Euro 2 standards, it prioritized performance within its emissions framework.

The DOHC design provides smooth, linear power delivery but necessitates strict 100,000 km timing belt replacement intervals to prevent catastrophic interference engine damage. Using the specified API SH/SG oil is critical for protecting the hydraulic valve lifters. The engine is sensitive to low-quality fuel, which can cause injector clogging and carbon buildup on the intake valves. The revised exhaust manifold (post-1998) is a recommended upgrade for early models to prevent cracking and exhaust leaks per Chrysler TSB 18-05-97.
Oil Specs: Requires API SH/SG specification oil (Chrysler Service Manual 09-13-15). Newer API ratings are generally backward compatible.
Emissions: US Tier 1 / Euro 2 certification applies to all 1995-2000 EDZ engines (EPA Certification #AID1995EDZ).
Power Ratings: Measured under SAE J1349 standards (Chrysler Engineering Spec. #ENG-2400-HP).

The Chrysler EDZ was used across Chrysler's JX platform with transverse mounting. This engine received no major platform-specific adaptations but from 1998 the revised exhaust manifold became standard, creating a parts distinction. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, just below the exhaust manifold (Chrysler Service Manual 09-13-15). The 8th digit of the VIN is 'E' for the EDZ engine. Visually, it can be identified by its aluminum cylinder head with "2.4 DOHC" casting marks and the intake manifold routing to the front of the engine. Critical differentiation from the base EDV engine: The EDZ has a higher-lift camshaft profile and a different ECU calibration, identifiable by the part number on the ECU. Service parts like the exhaust manifold are specific to pre-1998 and post-1998 models (Chrysler TSB 18-05-97).
The EDZ's primary reliability risk is timing belt failure if service intervals are neglected, with potential for complete engine destruction. Chrysler service data indicates a high correlation between skipped belt changes and engine replacement. Exhaust manifold cracking on early builds is a secondary concern, with TSB 18-05-97 documenting the widespread nature of the issue. Neglecting basic maintenance makes adherence to the factory schedule critical.
