The Renault F4R 741 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 2000 and 2006. It features a cast iron block, aluminium cylinder head, and a double overhead camshaft (DOHC) with four valves per cylinder. Output was typically 100 kW (136 PS), with torque peaking at 191 Nm, offering a refined and responsive driving experience.
Fitted to models such as the Mégane II, Laguna II, and Scénic II, the F4R 741 was engineered for a balance of performan…
Production years 2000–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5683).
The Renault F4R 741 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact and family hatchbacks/estates (2000-2006). It combines a robust cast iron block with a DOHC 16-valve design to deliver smooth, linear power and refined operation. Designed to meet Euro 3 emissions standards, it prioritized drivability and mechanical refinement for its era.

The Renault F4R 741 was used across Renault's Mégane II/Laguna II platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and was eventually replaced by the F4RT turbocharged engine, creating clear generational boundaries. All adaptations are documented in OEM technical bulletins.
The F4R 741's primary reliability risk is exhaust camshaft position sensor failure, with elevated incidence in high-mileage or humid environments. Renault workshop data indicates this is a common cause of no-start or erratic running conditions for engines over 100,000 km, while general owner feedback highlights it as a frequent electrical gremlin. Timely replacement of the entire timing belt kit is also critical to prevent catastrophic engine damage.
Analysis derived from Renault technical bulletins (2000-2006) and aggregated owner repair data (2002-2023). 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 741 can be very reliable long-term, but it has two key areas of concern: the timing belt system and the camshaft position sensor. Its DOHC engine is fundamentally robust. With the timing belt replaced strictly on schedule (every 90,000 km) and prompt attention to sensor issues, it can easily surpass 250,000 km. Neglecting these items will lead to expensive repairs or breakdowns.
The most critical issues are timing belt failure (causing catastrophic engine damage) and exhaust camshaft position sensor failure (causing no-start or erratic running). Other common problems include leaking camshaft seals and failing ignition coils. These are well-documented in Renault service manuals and are common wear-and-tear or electrical items.
The F4R 741 was used in the second-generation Renault Mégane (2002-2006), the second-generation Renault Laguna (2001-2005), and the second-generation Mégane Scénic (2003-2006). It was a standard 2.0L 16-valve petrol engine for these platforms, offering a good balance of power and economy.
Yes, it has good tuning potential. Common upgrades include a performance exhaust, a high-flow air filter, and ECU remapping, which can yield 10-15 kW extra. More significant power increases are possible with camshaft upgrades. Its robust bottom end makes it a solid foundation for mild to moderate tuning.
Fuel economy is typical for a 2.0L engine of the early 2000s. In a Renault Mégane II, expect around 8.5 L/100km (33 mpg UK) in combined driving. Highway cruising can be around 6.5 L/100km (43 mpg UK), while city driving will be higher, around 11 L/100km (25 mpg UK).
Yes. The F4R 741 is an interference engine. If the timing belt were to break or jump, the pistons will collide with the open valves, causing severe and expensive internal damage. This makes adhering to the 90,000 km timing belt replacement interval absolutely critical.
Renault recommends a mineral or semi-synthetic 10W-40 or 5W-40 engine oil meeting ACEA A3 specification. Full synthetic is also suitable and may offer better high-temperature protection. Change the oil and filter every 10,000 km or annually for best engine life.
