Renault F4R Engine Specs

The Renault F4R is a 2.0-liter naturally aspirated inline-four petrol engine produced since 1999, used across a broad range of Renault and Dacia models including the Megane, Laguna, Scenic, and Duster. As one of Renault's longest-serving mainstream four-cylinder engines, the F4R represents a straightforward, dependable approach to mid-size petrol power, prioritizing smoothness and everyday usability over outright performance.

Producing 135-143hp and 191-195Nm of torque from 1,998cc, the F4R uses a DOHC 16-valve aluminum head and a compression ratio of 9.8:1, with conventional multi-point fuel injection keeping the fuel system simple and inexpensive to service. This mechanical simplicity - no turbocharger, no direct injection - has helped the F4R build a reasonably solid reliability reputation across its more than two decades in production, particularly in the rugged Dacia Duster application, where it has proven itself in demanding conditions across a wide range of markets.

A handful of maintenance items are worth checking on a used example. The timing belt (used on most F4R applications) is a critical, interference-engine component and must be replaced strictly on schedule along with the water pump, since belt failure causes significant valve damage - this is one of the most important service items to verify on any used F4R-powered vehicle. Some examples develop minor oil leaks from valve cover or crankshaft seals as they age, generally straightforward and inexpensive to address. Spark plugs and ignition coils should be replaced according to schedule to maintain smooth running and fuel economy. Given the engine's widespread use in the Duster - a vehicle often bought specifically for its low running costs and simplicity - the F4R's reputation for being cheap and straightforward to maintain has become a meaningful part of its appeal, and parts availability remains good across the Renault and Dacia dealer networks as well as independent workshops in most markets where these vehicles are sold.
