The Renault F4R 701 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 1998 and 2008. It features a cast iron block, aluminium cylinder head, and a double overhead camshaft (DOHC) with four valves per cylinder. Output ranged from 96 kW (131 PS) to 100 kW (136 PS), with torque figures around 180–185 Nm, providing a balance of performance and refinement.
Fitted to models such as the Megane 2 (LM/PM), Laguna 2 (B56), and Scenic 2 (JM), the F4R 701 was eng…
Production years 1998–2002 meet Euro 3 standards; 2003–2008 models meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5682).
The Renault F4R 701 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact and mid-size applications (1998-2008). It combines a DOHC 16-valve valvetrain with multipoint fuel injection to deliver smooth, refined performance. Designed to meet Euro 3 and Euro 4 emissions standards, it balances spirited drivability with low running costs.

The Renault F4R 701 was used across Renault's Megane 2 and Laguna 2 platforms with transverse mounting. This engine received minor revisions in 2003-including updated camshaft profiles and ECU mapping-to improve durability and emissions compliance, creating slight interchange limits for pre- and post-2003 components. All adaptations are documented in OEM technical bulletins.
The F4R 701's primary reliability risk is timing belt failure due to neglected maintenance, with near-total engine destruction as the consequence. Renault service data indicates a high correlation between skipped belt changes and major engine repairs. A secondary, documented risk is exhaust camshaft lobe wear in pre-2003 units, linked to lubrication and thermal stress. Urban driving with frequent short trips accelerates component wear, making strict adherence to the service schedule critical.
Analysis derived from Renault technical bulletins (1998-2008) and UK DVSA failure statistics (2003-2015). 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 F4R 701 is generally reliable with a robust design. Its long-term reliability is heavily dependent on preventative maintenance, especially the 60,000 km timing belt change and using the correct 5W-40 oil to prevent camshaft wear. Engines that have had this service performed regularly can easily exceed 200,000 km. Neglecting these services will lead to catastrophic or expensive failures.
The most critical issue is timing belt failure. Other common problems include premature exhaust camshaft lobe wear (especially in pre-2003 engines), ignition coil pack failure, and oil leaks from the rocker cover or sump gasket. Cooling system neglect can also lead to overheating.
The F4R 701 was primarily used in the second-generation Renault Megane (2002-2008), the second-generation Laguna (2001-2007), and the second-generation Scenic (2003-2009). It was fitted to various trim levels like Expression, Dynamique, and Privilege, often denoted by 2.0 or 16V badges.
Moderate power gains are possible due to the 16-valve DOHC design. Basic modifications like a performance exhaust, air filter, and ECU remap can yield gains of 10-15 kW. More aggressive tuning requires internal modifications and is generally not cost-effective for this engine.
Fuel economy is reasonable for its size and performance. Expect around 8.5-9.5 L/100km (30-33 mpg UK) in mixed driving for a Megane 2.0 16V. Highway cruising can drop consumption to 6.5-7.0 L/100km (40-43 mpg UK).
Yes. The F4R 701 is definitively an interference engine. If the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe and expensive damage to the valves, pistons, and potentially the cylinder head and block.
Renault recommends a good quality semi-synthetic 5W-40 engine oil meeting ACEA A3/B3 or equivalent specifications. This specific viscosity is critical for protecting the camshafts, especially in pre-2003 engines. Change intervals should be 15,000 km or 12 months.
