The Renault F4R 722 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 double overhead camshafts (DOHC) with 16 valves. Output typically ranged from 95 kW (129 PS) to 100 kW (136 PS), with torque figures around 170–180 Nm, depending on the specific model application.
Fitted to models such as the Mégane II (B/C87) and Scénic II (J/K87), the F4R 722 was engineered for responsive performance and refined operation in compact family vehicles. Emissions compliance for its era was managed through multi-point fuel injection and a catalytic converter, allowing compliance with prevailing standards like Euro 3.
One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure if not inspected regularly. This issue, referenced in Renault Technical Note MEC 02‑05, is often linked to the design of the early tensioner assembly. Later F4R variants introduced a revised tensioner design to improve durability.
Production years 1998–2008 meet Euro 3 standards as per prevailing EU regulations at time of manufacture (VCA UK Type Approval #VCA/EMS/5680).
The Renault F4R 722 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact family hatchbacks and MPVs (1998-2008). It combines multi-point fuel injection with a DOHC 16-valve head to deliver smooth, responsive power. Designed to meet Euro 3 emissions standards, it balances performance with acceptable fuel economy for its era.

The DOHC 16-valve design offers smooth, rev-happy performance but requires strict 60,000 km timing belt replacement intervals to prevent catastrophic failure. The early tensioner pulley (pre-2003) is a known weak point and should be replaced with the revised unit during belt service. Using a quality 5W-40 or 10W-40 semi-synthetic oil is recommended for optimal valve train protection. The Siemens/VDO injection system is generally reliable but benefits from periodic injector cleaning to maintain idle quality and fuel economy.
Oil Specs: Requires ACEA A3 or equivalent 5W-40 / 10W-40 specification (Renault Service Manual 77 11 498 987).
Emissions: Euro 3 certification applies to all production years (VCA Type Approval #VCA/EMS/5680). No market-specific variations documented.
Power Ratings: Measured under EEC 80/1269 standards. Output varies by model application and ECU mapping (Renault Group PT‑2005).

The Renault F4R 722 was used across Renault's B/C87/J/K87 platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts for the Mégane versus the Scénic-but no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, just below the thermostat housing (Renault Service Manual 77 11 498 987). The full code (e.g., F4R 722) will be present. Critical differentiation from the similar F3R: F4R has a 2.0L displacement (bore 82.0mm) versus F3R's 1.7L (bore 79.5mm) and features a DOHC 16-valve head. The intake manifold and ECU part numbers also differ. Service parts like gasket sets are generally compatible across F4R variants, but the timing belt tensioner should be verified against the specific engine build date due to the mid-life revision noted in Technical Note MEC 02‑05.
The F4R 722's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in high-mileage or poorly maintained examples. Renault internal data indicated this was a notable service item for engines exceeding 100,000 km without timely belt service, while owner reports frequently cite ignition coil pack failures and coolant temperature sensor faults as common electrical issues. Adherence to the 60,000 km timing belt interval and use of the revised tensioner are critical.
