The Renault K4M 700 is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 1999 and 2008. It features a dual overhead camshaft (DOHC), 16‑valve design with multi‑point fuel injection, delivering a balance of refinement and adequate power for compact vehicles. Output ranged from 70 kW (95 PS) to 79 kW (107 PS), depending on the specific ECU calibration and application.
Fitted to models like the Clio II, Mégane II, and Scénic, the K4M 700 was engineered for smooth, reliable daily commuting and family use. Its character is defined by linear power delivery and modest fuel consumption. Emissions compliance was achieved through electronic engine management and catalytic converters, meeting Euro 3 standards for most of its production run.
One documented concern is premature failure of the exhaust manifold, which can crack near the cylinder head flange, as noted in Renault technical bulletin TB‑02‑09. This issue is often linked to thermal cycling stress and material fatigue. The design was eventually superseded by updated K4M variants with revised manifold castings.
Production years 1999–2005 meet Euro 3 standards; 2006–2008 models may have Euro 4 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K4M 700 is a 1,598 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks and MPVs (1999-2008). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver smooth, economical performance. Designed to meet Euro 3 (and some Euro 4) standards, it prioritises reliability and low running costs for high-mileage use.

The DOHC design provides smooth, rev-happy performance but demands strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic failure. The documented exhaust manifold cracking issue necessitates visual inspection during services. Valve clearances are hydraulic and generally maintenance-free. The non-interference design offers protection if the timing belt snaps, though ancillary damage is still possible.
Oil Specs: Requires semi-synthetic 10W-40 meeting ACEA A3/B3 specification (Renault Service Manual 99-08).
Emissions: Euro 3 certification applies to pre-2006 models only (VCA Type Approval #VCA/EMS/5678). Some 2006-2008 models meet Euro 4 depending on market.
Power Ratings: Measured under EEC 80/1269 standards. Output varies by model and ECU map (Renault Homologation Sheet H-99-K4M).

The Renault K4M 700 was used across Renault's B/C platform vehicles with transverse mounting. This engine received minor ECU and intake manifold revisions for different applications, but the core architecture remained consistent. All variations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the block, below the exhaust manifold (Renault Service Manual 99-08). The full code "K4M 700" should be clearly visible. Visually, it is identifiable by its aluminium cylinder head, plastic intake manifold, and the presence of a distributorless ignition system with coil packs mounted on the valve cover. Differentiate from the K4J 1.4L by its larger displacement and specific engine code.
The K4M 700's primary reliability risk is exhaust manifold cracking, with elevated incidence in high-mileage or frequently short-trip vehicles. Renault internal quality reports from the early 2000s indicated this was a common cause of exhaust noise complaints and MOT failures. Neglecting the timing belt schedule remains a significant cause of roadside breakdowns. Regular inspections and adherence to service intervals are critical for preventing expensive repairs.
