The Renault K4M 724 is a 1,598 cc, inline‑four petrol engine produced between 2000 and 2015. It features a dual overhead camshaft (DOHC) layout with 16 valves and multi‑point fuel injection. In its standard 75 kW (102 PS) tune, it delivers 145 Nm of torque, providing adequate performance for urban and highway driving.
Fitted to models such as the Clio II/III, Mégane II, and Scénic II, the K4M 724 was engineered for dependable daily commuting and family use. Its design priorit…
Production years 2000–2005 meet Euro 3 standards; 2006–2015 models meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault K4M 724 is a 1,598 cc inline‑four petrol engine engineered for compact and family hatchbacks/MPVs (2000-2015). It combines multi‑point fuel injection with a DOHC 16‑valve head to deliver smooth, predictable power delivery. Designed to meet Euro 3 and Euro 4 standards, it prioritises reliability and serviceability for high‑mileage use.

The Renault K4M 724 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Scénic II and revised intake manifolds for the Mégane II-with no major facelift revisions affecting core compatibility. All adaptations are documented in OEM technical bulletins.
The K4M 724's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in high-mileage or poorly maintained vehicles. Renault internal service data indicates a notable number of camshaft replacements on pre-2006 engines before 150,000 km, while timing belt failures, though less common, can cause total engine destruction. Extended oil change intervals and low-quality oil make adherence to the manufacturer's maintenance schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K4M 724 can be very reliable long-term if its two critical needs are met: strict 15,000 km oil changes with the correct 5W-40 specification and timely 120,000 km timing belt replacement. Neglecting either can lead to expensive camshaft or engine failure. Well-maintained examples easily surpass 250,000 km.
The most common issues are exhaust camshaft lobe wear (especially pre-2006), timing belt failure if not replaced, coolant leaks from the plastic thermostat housing, and ignition coil pack failures. These are well-documented in Renault service bulletins and owner communities.
The K4M 724 1.6L 16V petrol engine was used in the Renault Clio II (2000-2005) and Clio III (2005-2012), Mégane II (2002-2008), and Scénic II (2003-2009). It was a mainstay engine for Renault's compact and family vehicle lineup during this period.
Yes, but gains are modest. An ECU remap can yield around +8-10 kW safely. More significant power increases require hardware like performance cams, a larger throttle body, or an exhaust manifold, which can be costly. It responds better to maintenance for optimal performance than aggressive tuning.
Fuel economy is respectable for its era. In a Clio or Mégane, expect around 7.5 L/100km (38 mpg UK) in combined driving. Highway cruising can drop to 5.8 L/100km (49 mpg UK), while city driving may consume 9.5 L/100km (30 mpg UK). Real-world figures vary with driving style and condition.
Yes. The K4M 724 is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing severe internal damage that often requires a complete engine rebuild or replacement. This makes the 120,000 km belt change critical.
Renault specifies a 5W-40 synthetic or semi-synthetic oil meeting RN0700 or RN0710 standards. Using the correct oil is paramount to prevent camshaft wear. Always change the oil and filter at 15,000 km intervals or annually, whichever comes first.
