The Renault K4M 804 is a 1,598 cc, inline‑four petrol engine produced between 2011 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering refined performance for compact and family vehicles. Output ranges from 84 kW (114 PS) to 88 kW (120 PS), with torque figures around 151–158 Nm, providing smooth, linear power delivery ideal for daily commuting.
Fitted primarily to the Clio IV, Captur I, and Mégane IV, the K4…
All production years (2011–2018) meet Euro 5 standards; select late-model variants (2017–2018) may meet Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Renault K4M 804 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for B/C-segment hatchbacks and crossovers (2011-2018). It combines multi-point fuel injection with DOHC 16-valve architecture to deliver smooth, predictable power and everyday drivability. Designed to meet Euro 5 (and select Euro 6) standards, it prioritizes refinement and fuel efficiency.

The Renault K4M 804 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Captur and revised exhaust manifolds in the Mégane IV-and from 2017 minor ECU updates for emissions, creating subtle interchange limits. All adaptations are documented in OEM technical bulletins.
The K4M 804's primary reliability consideration is its interference-design timing belt, where failure leads to catastrophic engine damage. Renault internal service data indicates that adherence to the 120,000 km replacement schedule is critical, while owner reports frequently cite ignition coil failures as a common electrical fault. Extended oil change intervals can contribute to sludge buildup, making scheduled maintenance non-negotiable for longevity.
Analysis derived from Renault technical bulletins (2011-2018) and UK DVSA failure statistics (2016-2023). 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 804 is generally reliable with diligent maintenance. Its main vulnerability is the timing belt; failure to replace it causes major engine damage. Ignition coils are a common wear item. Regular oil changes and timely belt service are crucial for achieving high mileage without major issues.
The most frequent issues are timing belt/tensioner failure if neglected, ignition coil pack failures causing misfires, electronic throttle body faults leading to idle issues, and coolant temperature sensor malfunctions. These are well-documented in Renault service information.
This 1.6L petrol engine was fitted to the fourth-generation Clio (2012-2018), first-generation Captur (2013-2018), and early fourth-generation Mégane (2016-2018). It was typically badged as '1.6 16V' across various trim levels like Expression, Dynamique, and GT Line.
Modest gains are possible. An ECU remap can typically yield an extra 5-8 kW (7-10 PS) and slightly improved torque. Bolt-on modifications like a less restrictive intake or exhaust offer marginal improvements. Significant power increases are impractical due to the naturally aspirated design.
Real-world fuel economy is decent. In a Clio IV or Captur, expect combined figures of approximately 6.2–7.0 L/100km (40–45 mpg UK). Consumption will be higher in city driving (7.5-8.5 L/100km) and lower on highways (5.0-5.8 L/100km), depending on driving style.
Yes. The K4M 804 is an interference engine. If the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe internal damage that usually necessitates a complete engine rebuild or replacement.
Renault specifies oil meeting the RN0700 standard, typically a 5W-40 synthetic or semi-synthetic. Using the correct specification is vital for engine protection. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
