The Chrysler 3.5L EGG is a 3,518 cc, 60° V6 petrol engine produced between 1993 and 1997. It features a cast‑iron block, aluminum cylinder heads, single overhead camshafts (SOHC), and 24 valves. This engine was designed as Chrysler's first modern overhead-cam V6, delivering 152 kW (207 PS) and 300 Nm of torque, marking a significant step up in refinement from its pushrod predecessors.
Fitted primarily to the Chrysler LHS, New Yorker, and Concorde sedans, the EGG was engineered for smooth, quiet operation and strong mid-range power for comfortable highway cruising. Emissions compliance was achieved through sequential multi‑port fuel injection and an electronic throttle body, meeting US Tier 1 and Euro 1 standards for its production period.
One documented engineering update addressed premature head gasket failure, particularly on early 1993–1995 units. This issue, referenced in Chrysler Technical Service Bulletin 18‑07‑95, was linked to insufficient gasket material around coolant passages. The fix involved a revised multi-layer steel (MLS) head gasket introduced during the 1996 model year.
Production years 1993–1997 meet US Tier 1 and Euro 1 emissions standards for applicable markets (EPA Certification #AID1993EGG).
The Chrysler 3.5L EGG is a 3,518 cc 60° V6 petrol engine engineered for premium sedans (1993-1997). 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 1 and Euro 1 standards, it prioritized refinement over raw economy.

The SOHC 24-valve design provides a broad torque curve ideal for relaxed cruising 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. The engine is sensitive to coolant quality; using incorrect coolant can accelerate head gasket failure. The revised MLS head gasket (post-1995) is a critical upgrade for early models to prevent coolant leaks into cylinders or oil per Chrysler TSB 18-07-95.
Oil Specs: Requires API SH/SG specification oil (Chrysler Service Manual 09-13-19). Newer API ratings are generally backward compatible.
Emissions: US Tier 1 / Euro 1 certification applies to all 1993-1997 EGG engines (EPA Certification #AID1993EGG).
Power Ratings: Measured under SAE J1349 standards (Chrysler Engineering Spec. #ENG-3500V6-HP).

The Chrysler 3.5L EGG was used across Chrysler's LH platform with longitudinal mounting. This engine received no major platform-specific adaptations but from 1996 the revised MLS head gasket 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 09-13-19). The 8th digit of the VIN is 'G' for the EGG 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 later EZD engine: The EGG has a different intake manifold runner design and a unique ECU calibration. Service parts like the head gasket are specific to pre-1996 and post-1996 models (Chrysler TSB 18-07-95).
The EGG'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. Head gasket failure on early builds is a secondary concern, with TSB 18-07-95 documenting the widespread nature of the issue. Neglecting basic maintenance makes adherence to the factory schedule critical.
