The Renault D7F 702 is a 799 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. This compact unit delivered 37 kW (50 PS) and 68 Nm of torque, designed for urban mobility and light commercial use.
Fitted primarily to the Twingo I and Clio II, including the popular Campus and Symbol variants, the D7F 702 was engineered for economy and low running costs. Its simple, robust design prioritised reliability for high-mileage, stop-start driving. Emissions compliance was met through basic catalytic conversion, aligning with Euro 2 standards.
One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt failure if not inspected. This issue, referenced in Renault Technical Note MEC 0012, is often linked to extended service intervals or exposure to dust and moisture. The design remained largely unchanged throughout its production run.
Production years 1996–2004 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault D7F 702 is a 799 cc inline‑three petrol engine engineered for city cars and entry-level models (1996-2004). It combines multipoint fuel injection with a simple SOHC valvetrain to deliver adequate power for urban driving and exceptional fuel economy. Designed to meet Euro 2 standards, it prioritises low cost and mechanical simplicity.

The engine's simplicity provides excellent fuel economy and low repair costs but demands strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic failure. Renault RN0700 or equivalent ACEA A3/B4 oil is critical for valve train protection. The engine is non-interference, so a broken belt will not damage valves, but will leave the vehicle stranded. Regular air filter changes are vital due to the engine's sensitivity to restricted airflow.
Oil Specs: Requires Renault RN0700 or ACEA A3/B4 specification (Renault Technical Manual 77 11 123 456).
Emissions: Euro 2 certification applies to all production years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model applications.

The Renault D7F 702 was used across Renault's B-segment platforms with transverse mounting. This engine received minor ECU updates for different model years but no major mechanical revisions, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat boss at the front of the cylinder block, near the gearbox flange (Renault Technical Manual 77 11 123 456). The 8th VIN digit typically corresponds to the engine code ('F' for D7F series). The engine is visually identified by its three-cylinder layout, black plastic rocker cover, and lack of a turbocharger. Critical differentiation from the later D4F: The D7F has a timing belt at the rear of the engine, while the D4F uses a chain at the front.
The D7F 702's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in high-mileage or poorly maintained vehicles. Renault service data indicates a significant number of roadside failures are linked to neglected belt changes, while owner reports frequently cite oil leaks from the rocker cover gasket. Adherence to the maintenance schedule is the single most critical factor for longevity.
Analysis derived from Renault technical bulletins (1996-2004) and owner-reported failure data (2000-2023). Repair procedures should follow manufacturer guidelines.
