Production years 1996–2000 meet Euro 2 standards; 2001–2005 meet Euro 3; 2006–2008 models meet Euro 4 compliance .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K7M 750 is renowned for its mechanical simplicity and potential for high mileage, but its reliability is entirely contingent on strict adherence to the 60,000 km timing belt replacement schedule. If this is followed, along with regular oil changes, the engine is very durable. Ignoring the timing belt will result in expensive engine damage.
The most critical issue is timing belt failure if neglected. Other common problems include ignition system faults (distributor cap, rotor, leads), coolant leaks from hoses or the thermostat housing, and idle instability caused by a dirty throttle body or faulty idle air control valve. These are well-documented in Renault service information.
This 1.6L 8-valve petrol engine was fitted to the second-generation Clio (1998-2005), first-generation Mégane (1996-2002), and first-generation Kangoo (1997-2008). It was typically badged as '1.6' across various trim levels like RN, RL, RT, and Expression.
Significant power gains are difficult due to the SOHC 8-valve design. Minor improvements can be had from a performance air filter, a free-flow exhaust, and an ECU remap, potentially yielding 5-8 kW (7-10 PS). However, the engine's design limits its potential compared to 16-valve variants.
Fuel economy is reasonable for its era. In a Clio II or Mégane I, expect combined figures of approximately 7.0–8.0 L/100km (35–40 mpg UK). Consumption will be higher in city driving (8.5-9.5 L/100km) and lower on highways (5.8-6.5 L/100km), depending on driving style and vehicle condition.
Yes. The K7M 750 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 requires a complete engine rebuild or replacement. This is why the 60,000 km replacement interval is non-negotiable.
Renault specifies oil meeting the RN0700 standard, typically a 10W-40 mineral or semi-synthetic for this engine. Using the correct specification is important for engine protection. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
