The Renault F4R 736 is a 1,998 cc, inline‑four petrol engine produced between 1998 and 2002. It features a dual overhead camshaft (DOHC) and 16 valves, delivering outputs around 100 kW (136 PS) and 180 Nm of torque. Its design prioritized a balance of performance and refinement for sportier models, using multi-point fuel injection for precise metering.
Fitted to models such as the Mégane I Coupe and Laguna I, the F4R 736 was engineered for responsive driving dynamics and spirited performance. Emissions compliance for its era was managed through catalytic converters and electronic engine management, meeting Euro 2 standards.
One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure. This issue, highlighted in Renault Service Information Bulletin 01 05 98, is often linked to bearing fatigue under sustained high-RPM operation. The design was revised in later F4R variants.
Production years 1998–2002 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5683).
The Renault F4R 736 is a 1,998 cc inline‑four petrol engine engineered for sporty compact and mid-size hatchbacks and coupes (1998-2002). It combines multi-point fuel injection with a dual overhead camshaft to deliver smooth, high-RPM power delivery. Designed to meet Euro 2 standards, it balances performance with adequate refinement for its vehicle class.

The DOHC 16-valve design offers spirited performance but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. The Bosch Motronic system is generally robust but sensitive to fuel quality; using clean, high-octane petrol is recommended. The timing belt tensioner pulley is a known wear item; replacement with the belt is advised. Regular coolant changes prevent corrosion in the cast-iron block.
Oil Specs: Requires CCMC G5 specification oil (Renault Owner's Manual 1998). ACEA A3/B3 is a suitable modern equivalent.
Emissions: Euro 2 certification applies to all production years (VCA Type Approval #VCA/EMS/5683).
Power Ratings: Measured under EEC 80/1269 standards (Renault Group PT‑1998).

The Renault F4R 736 was used across Renault's Mégane and Laguna platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping differences between Mégane Coupe and Laguna-and no significant facelift revisions 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, near the gearbox flange (Renault Tech Manual 6011). The 8th VIN digit often corresponds to the engine type ('F' for F4R series). Visually, it is identifiable by its dual cam covers and Bosch Motronic intake manifold with individual injectors. Critical differentiation from the F4P 775: The F4R 736 is the higher-output 136 PS variant used in sportier models, while the F4P 775 produced 125 PS. Service parts like timing belts and tensioners are generally interchangeable within the F4R family.
The F4R 736's primary reliability risk is timing belt tensioner pulley failure, a common issue across its production run. Renault workshop data indicates this is the most frequent cause for timing-related repairs. Ignoring the 60,000 km replacement interval can lead to catastrophic engine damage, making strict adherence to the schedule critical.
Analysis derived from Renault technical bulletins (1998-2002) and UK DVSA failure statistics (2000-2010). Repair procedures should follow manufacturer guidelines.
