The Renault K7M 750 is a 1,598 cc, inline‑four petrol engine produced between 1996 and 2008. It features a single overhead camshaft (SOHC) design with 8 valves and multi‑point fuel injection, delivering dependable, economical performance for compact vehicles. Output ranges from 55 kW (75 PS) to 66 kW (90 PS), with torque figures around 127–132 Nm, providing adequate power for city and light highway driving.
Fitted to models such as the Clio II, Mégane I, and Kangoo I, the K7M 750 was engineered for cost-effective, low-maintenance motoring. Emissions compliance was initially met through basic catalytic converter systems, allowing early units to meet Euro 2 standards, with later iterations achieving Euro 3 and Euro 4 compliance through revised engine management.
One documented engineering characteristic is the engine's simple, robust design, which contributes to its longevity but also results in a timing belt that requires replacement every 60,000 km or 4 years. This critical maintenance item, detailed in Renault Technical Note MEC‑96‑001, is non-negotiable to prevent severe engine damage due to its interference design.
Production years 1996–2000 meet Euro 2 standards; 2001–2005 meet Euro 3; 2006–2008 models meet Euro 4 compliance (VCA UK Type Approval #VCA/EMS/8901).
The Renault K7M 750 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and vans (1996-2008). It combines multi-point fuel injection with SOHC 8-valve architecture to deliver predictable, economical performance and straightforward serviceability. Designed to meet Euro 2, Euro 3, and Euro 4 standards, it prioritizes reliability and low running costs.

The SOHC 8-valve design offers predictable, economical performance ideal for city driving but mandates strict adherence to 60,000 km or 4-year timing belt replacement intervals to prevent catastrophic failure. Renault RN0700 (10W-40) oil is recommended for optimal protection. The engine runs best on standard unleaded petrol. Its simple design makes it easy to work on, but neglecting the timing belt will result in bent valves. The water pump is often driven by the timing belt and should be replaced simultaneously.
Oil Specs: Requires Renault RN0700 (10W-40) specification (Renault Technical Note LUB‑01‑005). Equivalent ACEA A3/B3 oils are acceptable.
Emissions: Emissions compliance varies by production year: Euro 2 (1996-2000), Euro 3 (2001-2005), Euro 4 (2006-2008) (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under ISO 1585 standards. Output varies by model application and ECU calibration (Renault Technical Manual 50A).

The Renault K7M 750 was used across Renault's B-segment platforms with transverse mounting. This engine received minor platform-specific adaptations-slightly different engine mounts in the Kangoo-but remained largely consistent throughout its production run, making it highly interchangeable. 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 50A). The 8th VIN digit typically corresponds to the engine type ('K' for K-series family). Engines feature a black plastic cam cover with '8V' branding. Critical differentiation from K4M series: K7M 750 has SOHC 8-valve design, while K4M engines are DOHC 16-valve. Service parts, particularly for the timing belt and water pump, are generally consistent across all applications but should be verified against the specific vehicle model year.
The K7M 750's primary reliability risk is catastrophic engine failure from a broken timing belt, a direct consequence of its interference design. Renault internal service data indicates that adherence to the strict 60,000 km replacement schedule is the single most critical factor for longevity, while owner reports frequently cite ignition system faults and coolant leaks as common wear items. Its simple design is robust, but neglecting scheduled maintenance is unforgiving.
Analysis derived from Renault technical bulletins (1996-2008) and UK DVSA failure statistics (2010-2020). Repair procedures should follow manufacturer guidelines.
