The Renault K4M 760 is a 1,598 cc, inline‑four petrol engine produced between 2006 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering outputs typically around 81 kW (110 PS) and 151 Nm of torque. Its compact dimensions made it ideal for transverse mounting in Renault's supermini and compact vehicle segments.
Fitted to popular models like the Clio III, Mégane III, and Scénic III, the K4M 760 was engineered f…
Production years 2006–2010 generally meet Euro 4 standards; 2011–2018 models may have Euro 5 compliance depending on market .
The Renault K4M 760 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for supermini and compact vehicles (2006-2018). It combines multi‑point fuel injection with a DOHC 16‑valve layout to deliver responsive low‑to‑mid range performance and urban drivability. Designed to meet Euro 4 (and some market‑specific Euro 5) standards, it prioritizes reliability and serviceability.

The Renault K4M 760 was used across Renault's B/C platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Scénic III and revised intake manifolds for the Mégane III-and from 2011 received minor ECU updates for emissions, creating minor software 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 K4M 760's primary reliability risk is exhaust camshaft lobe wear on early builds, with elevated incidence in high-mileage or poorly maintained vehicles. Internal Renault service data indicated a notable number of pre-2010 engines required camshaft replacement before 150,000 km, while general owner feedback highlights timing chain tensioner rattle as a common annoyance. Extended oil change intervals or use of incorrect oil viscosity significantly increase camshaft wear risk.
Analysis derived from Renault technical bulletins (2006-2012) and owner-reported failure data (2012-2023). 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 K4M 760 is generally robust, but early models (pre-2010) are known for camshaft wear. Later engines and those with the updated camshaft are significantly more reliable. Regular oil changes with the correct 5W-40 specification are crucial for preventing major issues and ensuring longevity beyond 200,000 km.
The most frequent issues are exhaust camshaft lobe wear (pre-2010), timing chain tensioner rattle, coolant temperature sensor failure, and valve cover gasket leaks. These are well-documented in Renault service notes and are common points of discussion in owner communities.
This 1.6L petrol engine was widely used in Renault's lineup from 2006-2018. Key models include the Clio III (2006-2012), Mégane III (2008-2016), Scénic III (2009-2016), and Kangoo II (2010-2018), typically badged as '1.6 16v'.
Yes, modest gains are possible. ECU remapping can yield around +10-15 kW. Bolt-on modifications like a performance exhaust and air filter can complement this. Significant power increases require internal upgrades, as the stock engine is tuned for reliability over performance.
Fuel economy is reasonable for its era. Expect around 8.2 L/100km in city driving and 5.3 L/100km on the highway, translating to approximately 34 mpg UK combined. Real-world figures vary based on driving style and vehicle condition.
Yes. The K4M 760 is an interference engine. If the timing chain fails or jumps, the pistons can collide with the open valves, causing catastrophic engine damage. This underscores the importance of addressing any timing chain rattle promptly.
Renault specifies a 5W-40 synthetic oil meeting the RN0700 standard. Using the correct oil is critical, especially for protecting the camshaft. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
