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 K4M 804 was engineered for responsive urban driving and efficient highway cruising. Emissions compliance was enhanced through electronic throttle control and revised combustion mapping, allowing all units to meet Euro 5 standards, with some late-production variants achieving Euro 6 compliance in specific markets.
One documented engineering update is the introduction of a revised timing belt tensioner and water pump assembly, addressing premature wear concerns noted in earlier K4M variants. This improvement, detailed in Renault Technical Note MEC‑11‑008, was implemented to enhance long-term durability and reduce maintenance-related failures in high-mileage applications.
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 naturally aspirated design offers predictable, linear power perfect for city traffic but mandates strict adherence to 120,000 km or 5-year timing belt replacement intervals to prevent catastrophic failure. Renault RN0700 (5W-40) oil is essential for optimal valvetrain protection. The engine performs best with E10 petrol meeting EN 228 standards. Late-model engines (post-2015) benefit from the revised tensioner and water pump per Renault Technical Note MEC‑11‑008, improving reliability. The electronic throttle body requires periodic cleaning to maintain smooth idle and throttle response.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Technical Note LUB‑01‑005). Equivalent ACEA A3/B4 oils are acceptable.
Emissions: Euro 5 certification applies universally (VCA Type Approval #VCA/EMS/6789). Euro 6 compliance confirmed for specific 2017-2018 models in designated markets.
Power Ratings: Measured under ISO 1585 standards. Output varies by model application and ECU calibration (Renault Technical Manual 60B).

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.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault Tech. Manual 60B). The 8th VIN digit typically corresponds to the engine type ('K' for K4M family). Engines feature a textured grey plastic cam cover with '16V' branding. Critical differentiation from K4M 753: K4M 804 uses a Continental ECU with a specific part number suffix; K4M 753 uses a Siemens ECU. Service parts, particularly for the timing kit and water pump, require verification of the engine's production date for compatibility with the revised components per Renault Technical Note MEC‑11‑008.
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.
