The Renault K9K 714 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2007 and 2018. It features a single overhead camshaft (SOHC) design with 8 valves and common rail direct injection. In standard form, it delivers 66 kW (90 PS) and 200 Nm of torque, offering a balance of frugal fuel economy and accessible low — end pulling power for its class.
Fitted to popular models such as the Clio III, Captur, and Duster, the K9K 714 was engineered for global markets seeking d…
Production years 2007–2010 meet Euro 4 standards; 2011–2014 models meet Euro 5; 2015–2018 models meet Euro 6 depending on market .
The Renault K9K 714 is a 1,461 cc inline‑four turbo‑diesel engineered for compact and crossover vehicles (2007-2018). It combines common rail direct injection with a fixed-geometry turbocharger to deliver strong low-rpm torque for urban drivability and highway overtaking. Designed to meet Euro 4 through Euro 6 standards, it prioritizes fuel efficiency and low running costs.

The Renault K9K 714 was used across Renault's B/C-segment platforms with transverse mounting. This engine received minimal platform-specific adaptations-standard engine mounts across all applications-with no major facelift revisions affecting core compatibility during its production run. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Renault technical bulletins (2007-2018) and owner-reported failure data (2015-2023). 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 K9K 714 is generally robust and economical, but its long-term reliability is heavily dependent on addressing two key issues: the EGR system and the timing belt. Engines with strict adherence to the 60,000 km belt change interval and proactive EGR maintenance can easily exceed 200,000 km. Neglecting these can lead to expensive repairs.
The most frequent issues are EGR valve and cooler clogging (causing running issues), timing belt failure (if neglected), glow plug system faults (causing cold-start problems), and DPF regeneration issues (causing limp mode). These are well-documented in Renault service information.
This 1.5L dCi diesel engine was primarily used in the Renault Clio IV (2012-2018), Captur (2013-2018), and Duster (2012-2018). It was also fitted to the Dacia Sandero Stepway (2012-2018) as the 1.5 dCi 90 variant. All applications are transverse, front-wheel drive.
Aftermarket ECU tuning is common on the K9K-714 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is excellent. In a Clio IV, expect ~4.8 L/100km (city) and ~3.6 L/100km (highway), or around 65 mpg UK combined. The heavier Captur or Duster will return slightly higher consumption, typically 55-60 mpg UK on mixed driving. Figures vary with driving style and vehicle condition.
Yes. The K9K 714 is an interference engine. If the timing belt snaps or jumps, the pistons will collide with the open valves, causing catastrophic internal damage requiring a full engine rebuild or replacement. This makes the 60,000 km belt change interval absolutely critical.
Renault mandates oil meeting the RN0720 specification, typically a 5W-30 low-SAPS (low ash) synthetic grade designed for diesel engines with particulate filters. Using the correct oil is vital for protecting the DPF and EGR systems. Change intervals should not exceed 20,000 km or 12 months.
