The Renault K4J 710 is a 1,390 cc, inline‑four naturally aspirated petrol engine produced between 2000 and 2008. It features an aluminium block and cylinder head, a double overhead camshaft (DOHC) with four valves per cylinder, and multi-point fuel injection. Output is 72 kW (98 PS), with torque peaking at 127 Nm, offering a balance of efficiency and responsive performance for compact vehicles.
Fitted primarily to the Clio II RS 172 Cup, Mégane II, and Scénic II, the K4J 710 was engineered for sporty, agile driving with a free-revving character. Its 16-valve design prioritised mid-range torque and high-RPM power over low-end grunt. Emissions compliance for its era was managed through electronic fuel injection and a catalytic converter, meeting Euro 3 standards.
One documented characteristic is sensitivity to timing belt failure, which can lead to catastrophic engine damage due to its interference design. This critical maintenance interval is emphasized in Renault's technical documentation for the Clio RS. The engine received no major updates during its production run before being superseded by the more powerful K4M engine.
Production years 2000–2008 meet Euro 3 standards as per applicable regulations (VCA UK Type Approval documentation for relevant model years).
The Renault K4J 710 is a 1,390 cc inline‑four naturally aspirated petrol engineered for sporty hatchbacks and MPVs (2000-2008). It combines an aluminium construction with a DOHC 16-valve valvetrain to deliver responsive power and a high-revving character. Designed to meet Euro 3 emissions standards, it prioritises mechanical precision and driver engagement over ultimate fuel economy.

The engine delivers a sporty, responsive driving experience but demands strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic failure. The high compression ratio requires good quality 95 RON petrol for optimal performance and to prevent knocking. Using the correct semi-synthetic 5W-30 oil is essential for protecting the DOHC valvetrain. The free-revving nature encourages spirited driving, which can accelerate wear if maintenance is neglected.
Oil Specs: Requires SAE 5W-30 semi-synthetic oil specification (Renault Owner's Manual).
Emissions: Euro 3 certification applies to vehicles manufactured during this period (VCA Type Approval Database for relevant Renault models).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across applications (Renault Group PT Archive).

The Renault K4J 710 was used across Renault's Clio II, Mégane II, and Scénic II platforms with transverse mounting. This engine received no significant platform-specific adaptations during its production run. All applications 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. The code will read "K4J 710" followed by a serial number. Visually, it is a compact, all-aluminium engine with a twin-cam cover and a plastic intake manifold. Differentiate from the K4M (1.6L) by displacement and from the K4J 712 (higher power) by the specific power output and ECU mapping. Service parts are generally compatible across all K4J 710 applications.
The K4J 710's primary reliability risk is timing belt failure due to neglect, with elevated incidence in vehicles exceeding the 60,000 km service interval. Renault service documentation highlights the critical nature of this maintenance, while owner reports frequently cite ignition coil and sensor failures as common causes of drivability problems. Addressing these specific maintenance items is critical for long-term reliability.
