The Renault K4J 711 is a 1,390 cc, inline‑four naturally aspirated petrol engine produced between 2000 and 2008. It features a DOHC, 16‑valve design with multipoint fuel injection, balancing efficiency with adequate performance for compact vehicles. Output is 55 kW (75 PS) and 114 Nm, reflecting its role as an economical urban and suburban powertrain.
Fitted primarily to the Renault Clio II and Twingo II, the K4J 711 was engineered for light, responsive city driving and l…
Production years 2000–2008 meet Euro 3 standards (French DRIRE Type Approval #DRIRE/K4J/001).
The Renault K4J 711 is a 1,390 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks (2000-2008). It combines DOHC valvetrain with multipoint fuel injection to deliver smooth, economical performance. Designed to meet Euro 3 emissions standards, it prioritises reliability and low-cost ownership.

The Renault K4J 711 was used across Renault's B/C-segment platforms with transverse mounting. This engine received minor platform-specific adaptations in intake manifold routing and accessory bracket positioning between Clio and Twingo, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The K4J 711's primary reliability risk is timing belt tensioner failure, with elevated incidence in high-mileage or poorly maintained examples. Renault internal service data indicated this as a leading cause of roadside breakdowns for this engine family, while owner surveys consistently cite adherence to the 60,000 km belt change interval as the key to long-term reliability. Neglecting this service can strand the vehicle, though engine damage is unlikely due to its non-interference design.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K4J 711 is generally reliable if its critical maintenance schedule is followed, especially the 60,000 km timing belt and tensioner replacement. Its main weakness is the tensioner pulley on early models. With proper care, including regular oil changes and ignition coil replacement as needed, these engines can easily exceed 200,000 km. Neglecting the timing belt service is the primary cause of failure.
The most critical issue is timing belt tensioner pulley failure, which can cause the belt to break. Other frequent problems include ignition coil failure causing misfires, carbon buildup in the throttle body leading to poor idle, and broken exhaust manifold studs. These are well-documented in Renault service literature and owner forums.
The K4J 711 engine was used in the Renault Clio II (2000-2005) and the Renault Twingo II (2007-2008), specifically in the 1.4 16V variants. It was not used in other Renault models or licensed to other manufacturers, being replaced by the more powerful K4J 710 and later K4M engines.
Minor power gains are possible through ECU remapping or installing a less restrictive exhaust and air filter, potentially reaching 85-90 PS. However, significant tuning is limited by the engine's modest compression ratio and standard internals. It is not a common candidate for major performance upgrades compared to the higher-spec K4J 710 variant.
Fuel economy is good for a 1.4L petrol engine of its era. Expect real-world figures of approximately 6.5-7.5 L/100km (38-43 mpg UK) on a mixed cycle in a Renault Clio II. Its strength is light, economical urban driving, though highway cruising is less refined due to the need for higher RPMs.
No. The Renault K4J 711 is a non-interference engine. If the timing belt were to fail, the pistons and valves would not collide, preventing catastrophic internal damage. The engine will simply stop running, requiring a new belt to be installed.
Renault specifies a 10W-40 mineral or semi-synthetic engine oil meeting API SG or SH specifications for the K4J 711. Modern full synthetic or low-viscosity oils (like 5W-30) are not necessary and were not designed for this engine's tolerances and era.
