The Dodge ERB is a 3,301 cc, 90° V6 engine produced between 1990 and 1996. Developed as part of Chrysler's Magnum series, it features a cast — iron block with aluminum heads, SOHC 12 — valve configuration, and multi — port fuel injection. It delivered 132 kW (177 PS) at 4,400 rpm and 278 Nm of torque at 2,800 rpm, providing strong low — end pull suitable for full — size sedans and police applications.

Production years 1990–1995 meet U.S. EPA Tier 0 standards; 1996 models comply with OBD-II requirements (EPA Certification #EPAPDF0418).
The Dodge ERB is a 3,301 cc 90° V6 engineered for fleet and passenger applications (1990–1996). It combines SOHC 12-valve architecture with multi-port fuel injection to deliver strong low-end torque and smooth cruising performance. Designed to meet U.S. EPA Tier 0 and early OBD-II standards, it balances durability with drivability.

The Dodge ERB was used across Dodge's Monaco and New Yorker platforms with longitudinal mounting and RWD configuration. This engine received platform-specific adaptations-intake tuning in the Monaco Police Package and simplified emissions controls in fleet-spec units-and from 1996 the OBD-II compliance update introduced revised ECU mapping, creating interchange limits. 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 ERB's primary reliability risk is intake manifold cracking due to thermal cycling, with elevated incidence in high-mileage fleet vehicles. Internal Chrysler field reports from 1994 indicated over 25% of pre-1993 engines exhibited vacuum leaks by 100,000 km, while NHTSA data links manifold failures to idle instability in police and taxi fleets. Extended idling and frequent temperature swings accelerate cracking, making inspection and timely replacement critical.
Analysis derived from Dodge technical bulletins (1990-1996) and NHTSA field reports (1992-1997). 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 ERB is fundamentally durable, especially in fleet applications, but pre-1993 models are prone to intake manifold cracking if not inspected. The non-interference timing design reduces risk of major damage from belt failure. With proper maintenance—quality oil, coolant, and belt service—many examples exceed 200,000 km reliably.
Key issues include intake manifold cracking (pre-1993), ignition coil pack failure, water pump leaks, and EGR valve clogging. These are documented in Dodge service bulletins. Regular inspection and timely replacement of known weak components significantly reduce risk of major failures.
The ERB was used in the Dodge Monaco (1990–1996) and New Yorker (1990–1993). It was primarily offered in full-size sedans for consumer and law enforcement use. The engine was not used in minivans or trucks, remaining exclusive to Chrysler's B-body platform.
Yes, the ERB responds well to modifications. Intake/exhaust upgrades, cam swaps, and ECU tuning can yield 15–25 kW gains. Forced induction is possible but requires significant supporting mods. Stock internals are robust, but head gasket integrity should be verified before high-boost use.
Moderate for a V6. In the Dodge Monaco, EPA ratings are ~14 mpg (city) and ~21 mpg (highway) (~17 L/100km, ~11 L/100km). Real-world driving typically yields 16–19 mpg (15–12 L/100km). Fuel quality and driving style significantly affect consumption.
No. The ERB uses a non-interference valvetrain design. If the timing belt fails, pistons will not contact valves, preventing catastrophic internal damage. This enhances reliability in fleet applications where maintenance intervals may be extended.
Use SAE 10W-30 or 5W-30 engine oil meeting API SH or SL specifications. Change oil every 9,000–12,000 km to protect valve train components. High-quality synthetic oil is recommended for high-load or high-mileage applications.
