The Renault F3P 720 is a 1,721 cc, inline‑four petrol engine produced between 1989 and 1996. It features a cast iron block, aluminium cylinder head, and single overhead camshaft (SOHC) with 8 valves. Output ranged from 72 kW (98 PS) to 79 kW (107 PS), with torque figures around 140–145 Nm, providing adequate performance for its era.
Fitted to models such as the Clio 1 (B/C57), Megane 1 (BA/BB0), and Kangoo (KC), the F3P 720 was engineered for reliability and cost-effective motoring. It offered a balance of fuel economy and sufficient power for urban and highway driving. Emissions compliance for its production period was met under prevailing standards, typically pre-Euro or Euro 1.
One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure if not inspected. This issue, noted in Renault service documentation, is often linked to component fatigue over time. The engine was eventually superseded by newer F-series and K-series units.
Production years 1989–1996 fall under pre-Euro or Euro 1 emissions standards depending on specific model year and market (VCA UK Type Approval applicable for registered imports).
The Renault F3P 720 is a 1,721 cc inline‑four petrol engine engineered for compact and light commercial vehicles (1989-1996). It combines a robust cast iron block with a SOHC 8-valve head to deliver dependable, economical performance. Designed for the emissions standards of its era, it prioritises mechanical simplicity and serviceability.

The SOHC design offers mechanical simplicity and ease of repair but requires strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic failure. Using the correct viscosity oil (10W-40/15W-40) is critical for maintaining hydraulic tappet function and overall engine longevity. The injection system, while robust, benefits from clean fuel and periodic injector cleaning. Early detection of tensioner pulley wear, as noted in service bulletins, is key to avoiding belt damage.
Oil Specs: Requires mineral or semi-synthetic 10W-40/15W-40 (Renault Service Manual 77 11 298 999). Modern full-synthetics may be used if viscosity is correct.
Emissions: Euro 1 certification applies to later production models only (VCA Type Approval applicable for specific UK-registered vehicles). Most units are pre-Euro.
Power Ratings: Measured under EEC standards. Output varies by model application and injection type (Renault Homologation Data).

The Renault F3P 720 was used across Renault's Clio 1, Megane 1, and Kangoo platforms with transverse mounting. This engine received minor ECU and accessory adaptations between models, but the core architecture remained consistent. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, near the gearbox flange. The full code (e.g., F3P 720) should be clearly visible. Cross-reference this with the vehicle's VIN and service documentation. Visually, it is identifiable by its SOHC 8-valve cylinder head and distributor-based ignition system (on earlier variants).
The F3P 720's primary reliability risk is timing belt or tensioner failure, with elevated incidence in high-mileage or poorly maintained vehicles. Renault service documentation strongly emphasises the 60,000 km replacement interval. Neglecting this, or using incorrect oil, can lead to costly engine damage.
