The Renault F4P 722 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 1996 and 2000. It features a cast iron block, aluminium cylinder head, and a double overhead camshaft (DOHC) with four valves per cylinder. Output was typically 98 kW (133 PS), with torque peaking at 180 Nm, offering a significant performance upgrade over the SOHC F3R.
Fitted to sportier variants like the Mégane I Coupe and Scénic RX4, the F4P 722 was engineered for a more dynami…
Production years 1996–2000 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5681).
The Renault F4P 722 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for sporty compact and family vehicles (1996-2000). It combines a robust cast iron block with a DOHC 16-valve design to deliver responsive, high-revving power. Designed to meet Euro 2 emissions standards, it prioritized performance and driver engagement for its era.

The Renault F4P 722 was used across Renault's Mégane I platform with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and was eventually replaced by the F4R engine, creating clear generational boundaries. All adaptations are documented in OEM technical bulletins.
The F4P 722's primary reliability risk is intake manifold failure, with elevated incidence in high-mileage or frequently heat-cycled engines. Renault workshop data indicates this is a common repair item for engines over 120,000 km, while general owner feedback highlights it as a frequent cause of drivability issues. Timely replacement of the timing belt is also critical to prevent catastrophic engine damage.
Analysis derived from Renault technical bulletins (1996-2000) and aggregated owner repair data (1998-2023). 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 F4P 722 can be reliable long-term, but it has two critical failure points: the plastic intake manifold and the timing belt. Addressing these proactively is key. The DOHC engine itself is robust. With the manifold replaced and the timing belt changed on schedule, it can easily surpass 200,000 km. Neglecting these items will almost certainly lead to expensive repairs.
The most critical issues are cracking of the plastic intake manifold (leading to coolant leaks) and timing belt failure (causing catastrophic engine damage). Other common problems include leaking camshaft seals and failing ignition coils. These are well-documented in Renault service manuals.
The F4P 722 was primarily used in the sportier variants of the first-generation Renault Mégane, specifically the Mégane Coupe and the Mégane Scénic RX4, between 1996 and 2000. It was the performance petrol engine for this platform before the F4R arrived.
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 and head work, leveraging its 16-valve design. Its robust bottom end makes it a solid foundation for tuning.
Fuel economy is typical for a 2.0L performance engine of the late 90s. In a Renault Mégane Coupe, expect around 9.5 L/100km (30 mpg UK) in combined driving. Highway cruising can be around 7.5 L/100km (38 mpg UK), while aggressive city driving will push consumption to 12-13 L/100km (21-23 mpg UK).
Yes. The F4P 722 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 for the twin camshafts. Change the oil and filter every 10,000 km or annually for best engine life.
