The Renault K7M 720 is a 1,598 cc, inline‑four petrol engine produced between 1996 and 2005. It features a single overhead camshaft (SOHC) layout with 8 valves and multi‑point fuel injection. In standard form, it delivered 55 kW (75 PS) and 114 Nm of torque, offering dependable urban performance and straightforward mechanical serviceability.
Fitted to models such as the Clio I, Mégane I, and Kangoo, the K7M 720 was engineered for economical, low-maintenance motoring. Emissions compliance was achieved through electronic fuel injection and a three‑way catalytic converter, meeting Euro 2 standards for its primary production run.
One documented characteristic is its robust, non-interference valvetrain design, which provides a safety margin in the event of timing belt failure. This design, referenced in Renault Technical Note MEC 0321, was a deliberate choice for cost-effective production and service, prioritizing durability over high specific output.
All production years (1996–2005) meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/4567).
The Renault K7M 720 is a 1,598 cc inline‑four petrol engine engineered for compact hatchbacks and vans (1996-2005). It combines multi‑point fuel injection with a SOHC 8‑valve head to deliver predictable, low-stress performance and economical cruising. Designed to meet Euro 2 standards, it prioritizes mechanical simplicity and serviceability over peak performance.

The SOHC 8-valve design provides a torquey, low-revving character ideal for city driving and light loads but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. The non-interference valvetrain is a safety feature, meaning a broken belt will not cause piston-to-valve contact. The Magneti Marelli fuel injection system is robust but sensitive to poor electrical grounds; ensure battery and earth strap connections are clean. The catalytic converter is a separate component from the manifold, making replacement less costly than integrated designs.
Oil Specs: Requires Renault RN0700 (10W-40) specification for pre-2000 models; 5W-40 for later models (Renault Owner's Manual Ref. 77 11 308 542).
Emissions: Euro 2 certification applies to all models (1996-2005) (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under ISO 1585 standards. Output figures are for standard atmospheric conditions (Renault TIS Doc. MEC 0321).

The Renault K7M 720 was used across Renault's B‑segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Kangoo and revised exhaust manifolds for the Mégane I-creating minor service part variations. 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 TIS MEC 0321). The full engine designation is 'K7M 720'. Visually, it can be identified by its silver metal cam cover with '8V' embossed on top. Critical differentiation from the similar K7M 710: The 720 uses a Magneti Marelli fuel injection ECU, while the 710 uses a different system. Service parts, particularly for the ignition and fuel systems, are not always interchangeable between 710 and 720 variants.
The K7M 720's primary reliability strength is its simple, non-interference design, making it highly tolerant of missed maintenance. Renault internal service data indicated very few catastrophic engine failures, while owner reports frequently cite distributor cap and rotor arm wear as the most common service item. Adherence to the 60,000 km timing belt replacement interval is the single most critical maintenance task.
Analysis derived from Renault technical bulletins (1996-2005) and owner-reported failure data (2000-2023). Repair procedures should follow manufacturer guidelines.
