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 engine…
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.
Analysis derived from Chrysler technical bulletins (1993-1997) and NHTSA complaint data (1993-2002). 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 EGG can be reliable if meticulously maintained. Its Achilles' heel is the timing belt; failure destroys the engine. Regular oil changes prevent sludge. The revised MLS head gasket (post-1995) is more durable. With proper care, these engines can exceed 250,000 km.
The most critical issue is timing belt failure. Head gasket failure (pre-1996) is common. Oil sludge buildup from poor maintenance and associated transmission (A604) problems are also frequent. These are well-documented in Chrysler TSBs and owner reports.
The EGG was the premium V6 for Chrysler's first-generation LH platform. It powered the Chrysler LHS, New Yorker, and Concorde LXi from 1993 to 1997. It was not used in the base 3.3L variants of these cars.
Yes, but gains are modest. Simple mods include a cold air intake and cat-back exhaust, yielding 5-10 kW. ECU reflashing is limited. Significant power increases require internal work (cams, head porting) and are costly. It responds better to handling upgrades.
Expect around 14.1 L/100km (20 mpg US) in the city and 9.8 L/100km (28 mpg US) on the highway for a Concorde or LHS. Combined, it's approximately 11.8 L/100km (24 mpg US). This was respectable for a large V6 sedan in the mid-90s.
Yes, absolutely. The EGG is a classic interference engine. If the timing belt breaks or slips, the pistons will collide with the open valves, bending them and causing severe, often terminal, engine damage. Belt changes are non-negotiable.
Chrysler specifies API SH or SG rated oil, typically SAE 10W-30. Using a high-quality synthetic or semi-synthetic oil that meets this spec is highly recommended to combat sludge and protect the timing components.
