The Renault F4R 764 is a 1,998 cc, inline‑four petrol engine produced between 2001 and 2008. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection. In its most common application, it delivered 103 kW (140 PS) and 191 Nm of torque, providing a balance of performance and refinement for its era.
Fitted primarily to the Renault Laguna II (B96) and Espace IV (J64), the F4R 764 was engineered for smooth, linear power delivery and comfortab…
Production years 2001–2005 generally meet Euro 3 standards; 2006–2008 models typically comply with Euro 4 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault F4R 764 is a 1,998 cc inline‑four petrol engine engineered for mid‑size family vehicles (2001-2008). It combines DOHC 16-valve architecture with multi‑point fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 3 and Euro 4 standards, it prioritizes refinement and everyday drivability.

The Renault F4R 764 was used across Renault's Laguna II and Espace IV platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Espace for its MPV weight-and minor ECU mapping variations for different trim levels, creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
The F4R 764's primary documented concern is potential exhaust camshaft lobe wear, with elevated incidence in engines subjected to extended oil change intervals or incorrect oil. Renault internal data noted this issue primarily in high-mileage fleets, while general owner feedback highlights coil pack failures as a common electrical fault. Maintaining correct oil specification and level is critical for long-term engine health.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally yes, the F4R 764 is a robust and proven engine. Its main Achilles' heel is potential camshaft wear if oil changes are neglected or the wrong oil is used. With proper maintenance using RN0700/RN0710 oil, these engines can easily surpass 200,000 km. Common ancillary failures like coil packs are inexpensive to fix.
The most frequently reported issues are ignition coil pack failures causing misfires, oil leaks from the rocker cover gasket, and coolant leaks from the plastic thermostat housing. The more serious, but less common, issue is premature wear of the exhaust camshaft lobes, often linked to poor maintenance.
The F4R 764 was primarily used in the second-generation Renault Laguna (B96, 2001-2007) and the fourth-generation Renault Espace (J64, 2003-2008), specifically in their 2.0 16V (140 PS) petrol variants. It was not used in smaller models like the Mégane or Clio.
Yes, but gains are modest due to its naturally aspirated design. ECU remapping can yield around 10-15 kW extra by optimizing fuel and ignition maps. More significant power increases require forced induction (turbo/supercharger kits), which is complex and expensive. Most tuning focuses on improving throttle response rather than peak power.
Real-world fuel economy varies. In a Laguna II, expect around 9.5 L/100km in city driving and 6.5 L/100km on the highway, averaging 7.5-8.0 L/100km combined (approx. 31-35 mpg UK). The heavier Espace IV will consume slightly more. Driving style has a significant impact on consumption figures.
Yes. The F4R 764 is an interference engine. This means that if the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is very durable with proper oil maintenance.
Renault strongly recommends using engine oil that meets their RN0700 or RN0710 specifications, typically a 5W-40 synthetic or semi-synthetic. Using the correct oil is crucial for protecting the camshafts. The service interval should not exceed 15,000 km or 12 months, whichever comes first.
