The Renault F5R 701 is a 2,435 cc, inline‑four petrol engine produced between 1998 and 2003. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection. This naturally aspirated unit delivered 110 kW (150 PS) and 215 Nm of torque, engineered for smooth, linear power delivery suitable for larger Renault platforms.
Fitted primarily to the Laguna I and Espace III, the F5R 701 was designed for refined, comfortable cruising with an emphasi…
Production years 1998–2000 meet Euro 2 standards; 2001–2003 models meet Euro 3 standards .
The Renault F5R 701 is a 2,435 cc inline‑four petrol engine engineered for mid-size sedans and MPVs (1998-2003). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver smooth, predictable power and enhanced drivability. Designed to meet Euro 2 and Euro 3 emissions standards, it offers a balance of performance and environmental compliance for its era.

The Renault F5R 701 was used across Renault's Laguna I and Espace III platforms with transverse mounting. This engine received minor ECU updates but no major mechanical revisions affecting core compatibility occurred during its production run. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F5R 701 is generally robust, but its reliability is heavily dependent on strict adherence to the 60,000 km timing belt replacement interval. Neglecting this can lead to catastrophic engine failure. Crankshaft sensor failures are common but easily remedied. With proper maintenance, these engines can reliably exceed 200,000 km.
The most critical issue is timing belt failure if not replaced at 60,000 km. Other common problems include crankshaft position sensor failure, ignition coil pack failures, and coolant leaks from the thermostat housing. These are well-documented in Renault service information.
The F5R 701 was primarily used in the first-generation Renault Laguna (Phase 2, 1998-2003) and the third-generation Espace (1999-2003), specifically in the 2.5 16V petrol variants. It was not used in any other manufacturers' vehicles under license.
Yes, but gains are modest. An ECU remap can yield around +10-15 kW by optimizing ignition and fuel maps. More significant power requires hardware like performance cams, exhaust, and intake, which is costly. It's better suited to improving drivability than major power increases.
Real-world fuel economy is moderate to high. Expect around 11.0 L/100km (26 mpg UK) in urban driving and 7.5 L/100km (38 mpg UK) on the highway for a Laguna I. Combined figures typically range from 30-34 mpg UK, depending heavily on driving style and vehicle condition.
Yes. The F5R 701 is an interference engine. If the timing belt were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. This makes the 60,000 km belt replacement interval absolutely critical.
Renault mandates oil meeting RN0700 specifications, typically a 10W-40 semi-synthetic. Using ACEA A3 oil is the minimum requirement. Correct oil is crucial for overall engine health and longevity, though less critical for specific components like camshafts compared to later F4R engines.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
