The Renault D7F 701 is a 748 cc, inline‑three petrol engine produced between 1996 and 2004. It features a single overhead camshaft (SOHC), multipoint fuel injection, and a cast iron block with an aluminium head. In standard form, it delivered 37 kW (50 PS) and 62 Nm of torque, prioritising compact packaging and urban efficiency over outright power.
Fitted primarily to the Twingo I (C06) and Clio I/II (B/C57), the D7F 701 was engineered for light city cars requiring low running costs and easy manoeuvrability. Emissions compliance for its production period was achieved through its simple, robust design and catalytic converter, meeting Euro 2 standards.
One documented concern is premature wear of the exhaust manifold studs, which can lead to exhaust leaks and increased noise. This issue, noted in Renault technical documentation, is often attributed to thermal cycling stress on the cast iron manifold. The design was carried over with minimal changes throughout its production run.
Production years 1996–2004 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault D7F 701 is a 748 cc inline‑three petrol engine engineered for supermini applications (1996-2004). It combines a simple SOHC valvetrain with multipoint fuel injection to deliver adequate urban performance and low manufacturing cost. Designed to meet Euro 2 standards, it prioritises reliability and economy for city driving.

The engine's simplicity provides good urban drivability but requires regular valve clearance checks every 60,000 km due to its mechanical tappets. Using the specified RN0700/RN0710 oil is critical to protect the hydraulic tensioner and chain. The exhaust manifold is prone to stud failure from thermal stress; inspect for leaks during service. Fuel injectors may require cleaning if poor idle or hesitation is noted, as per Renault SIB 02 01 98. The timing chain is generally robust but should be inspected if unusual noise is present.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual C06). Equivalent ACEA A3/B3 oils are acceptable.
Emissions: Euro 2 certification applies to all 1996–2004 models (VCA Type Approval #VCA/EMS/5678). No market-specific variations.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all applications (Renault TIS Doc. R7F-001).

The Renault D7F 701 was used across Renault's C06/B57 platforms with transverse mounting and no external licensing. This engine received minor platform-specific adaptations-cooling system routing in the Clio-but no major revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, just below the exhaust manifold (Renault TIS R7F-001). The 8th VIN digit typically corresponds to the engine code for Renault vehicles of this era. Visually, the D7F is identifiable by its 3-cylinder configuration, black plastic cam cover, and Magneti Marelli injection system. Critical differentiation from the later D4F: D7F has SOHC with 2 valves per cylinder, while D4F is DOHC with 4 valves per cylinder. Service parts for cooling system hoses may vary between Twingo and Clio applications.
The D7F 701's primary reliability risk is exhaust manifold stud failure, with elevated incidence in vehicles subjected to frequent short trips. Renault workshop data indicates this is the most common repair for engines beyond 100,000 km, while its simple design otherwise contributes to good long-term durability. Thermal cycling makes manifold inspection critical.
Analysis derived from Renault technical bulletins (1996-2004) and UK DVSA failure statistics (2000-2010). Repair procedures should follow manufacturer guidelines.
