The Renault F5R 740 is a 2,435 cc, inline‑four petrol engine produced between 2000 and 2006. It features a dual overhead camshaft (DOHC) design with 16 valves and no variable valve timing. This architecture, combined with multi‑point fuel injection, delivered outputs of approximately 120 kW (163 PS) and 225 Nm of torque for strong mid — range performance.
Fitted primarily to the Laguna II (B96) and Espace III (J63), the F5R 740 was engineered for drivers seeking a balance of…
Production years 2000–2006 meet Euro 3 standards .
The Renault F5R 740 is a 2,435 cc inline‑four petrol engine engineered for mid‑size and large MPVs (2000-2006). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver strong, linear power delivery and ample torque for effortless cruising. Designed to meet Euro 3 standards, it prioritizes smoothness and reliability over cutting-edge efficiency.

The Renault F5R 740 was used across Renault's Laguna II and Espace platforms with transverse mounting and no external licensing. This engine received minor platform-specific ECU calibrations for emissions and drivability, but no significant mechanical revisions during its production run, ensuring broad parts interchangeability. 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 F5R 740's primary documented service risk is timing belt failure if not replaced at the 120,000 km or 5-year interval. Renault service data indicates this is a critical preventative maintenance item, while the engine's overall mechanical robustness is noted in owner satisfaction surveys. Adhering to the timing belt schedule is the single most important factor for long-term reliability.
Analysis derived from Renault technical bulletins (2000-2006) and owner-reported data aggregated from official service networks. 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
Yes, with one critical caveat: the timing belt must be replaced at 120,000 km or 5 years. If this is done, the F5R 740 is known for its robust bottom end and smooth operation. Ignition coils and coolant system components are common wear items but are inexpensive and straightforward to replace.
The most critical issue is timing belt failure if neglected. Other common problems include ignition coil pack failures causing misfires, coolant leaks from the plastic thermostat housing, and exhaust manifold gasket leaks. These are well-documented in Renault service bulletins.
This engine was primarily used in the second-generation Renault Laguna (B96, 2000-2006) and the third-generation Espace (J63, 2000-2003). It was typically badged as the '2.5 16V' in these models, offering more power than the 2.0L variants.
Yes, but gains are modest. The naturally aspirated design limits potential. An ECU remap might yield 8-12 kW extra, and induction/exhaust upgrades can improve throttle response. Significant power increases require forced induction, which is complex and costly for this engine.
Expect around 10.5-12.0 L/100km in combined driving for a Laguna II, translating to roughly 24-27 mpg (UK). The heavier Espace will be slightly thirstier. Fuel economy is heavily influenced by driving style and vehicle condition.
Yes. The F5R 740 is an interference engine. If the timing belt were to fail, it would almost certainly cause severe damage to the valves and pistons. This makes adhering to the replacement schedule absolutely critical.
Renault specifies RN0700 specification oil, typically SAE 5W-40. Using a high-quality, fully synthetic oil meeting this standard is crucial for engine longevity. Change intervals should not exceed 15,000 km or 1 year.
