The Renault F3P 707 is a 1,721 cc, inline‑four naturally aspirated petrol engine produced between 1989 and 1996. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with two valves per cylinder. Output varied by application but typically ranged from 66 kW (90 PS) to 72 kW (98 PS), delivering adequate performance for its era.
Fitted to models such as the Clio 1, 19, and Express, the F3P 707 was engineered for cost‑effective, reliable t…
Production years 1989–1996 meet Euro 1 standards as per applicable EU directives for vehicles of that era for reference models).
The Renault F3P 707 is a 1,721 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and saloons (1989-1996). It combines a simple SOHC valvetrain with multi-point fuel injection to deliver predictable, linear power delivery. Designed to meet Euro 1 emissions standards, it prioritizes mechanical simplicity and serviceability.

The Renault F3P 707 was used across Renault's Clio and 19 platforms with transverse mounting and no external licensing. This engine received minor ECU and accessory bracket adaptations between the Clio and 19, creating few interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The F3P 707's primary reliability risk is timing belt or tensioner failure, with elevated incidence in vehicles where service intervals are neglected. Renault service data indicates a high correlation between skipped belt changes and engine damage, while owner reports frequently cite tensioner pulley noise as an early warning sign. Adherence to the maintenance schedule is the single most critical factor for long-term reliability.
Analysis derived from Renault technical bulletins (1990-1996) and aggregated owner-reported failure data (1995-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The F3P 707 is fundamentally reliable if its critical maintenance, especially the 60,000 km timing belt change, is strictly followed. Neglecting this can lead to total engine failure. With proper care, including regular oil changes and coolant flushes, these engines can easily surpass 200,000 km.
The most critical issue is timing belt/tensioner failure. Other common problems include coolant leaks from the plastic thermostat housing, rough idle from a faulty idle control valve, and exhaust manifold cracks causing noise and fumes.
The F3P 707 was primarily used in the first-generation Renault Clio (1990-1996), the Renault 19 (1989-1996), and the Renault Express van/passenger variant (1989-1996). It was the higher-output 1.7L petrol option for these models.
Minor gains are possible via ECU remapping or installing a performance air filter and exhaust, but significant power increases are limited by the engine's 8-valve SOHC design. Most tuning focuses on improving throttle response rather than large power gains.
Fuel economy is modest by modern standards. Expect around 8.5–9.5 L/100km (30–28 mpg UK) in mixed driving for a Clio or 19. Highway driving can yield 6.5–7.5 L/100km (43–38 mpg UK), depending on condition and driving style.
Yes. The F3P 707 is an interference engine. If the timing belt breaks or slips, the pistons will collide with the open valves, causing severe and expensive internal damage. This makes the timing belt replacement interval absolutely critical.
Renault recommends a good quality SAE 10W-40 mineral or semi-synthetic oil. Modern ACEA A3/B3 specification oils are also suitable. Regular oil changes (every 10,000 km or annually) are essential for engine longevity.
