The Renault K4M 701 is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 1999 and 2008. It features a DOHC, 16‑valve design with multi‑point fuel injection, balancing efficiency with accessible performance for its segment. Output was rated at approximately 77 kW (105 PS) and 148 Nm, making it a popular choice for compact and mid-size Renault applications.
Fitted to models such as the Mégane II, Scénic II, and Laguna II, the K4M 701 was engineered for responsive daily driving and dependable service. Emissions compliance was achieved through electronic fuel injection and catalytic converter systems, meeting Euro 3 standards for its primary production period.
One documented service consideration is premature wear of the exhaust camshaft lobes, particularly in high-mileage examples, which can lead to reduced valve lift and performance loss. This issue, referenced in Renault Technical Bulletin TB‑K4M‑05, is often associated with infrequent oil changes or use of incorrect oil viscosity.
Production years 1999–2008 meet Euro 3 standards (French Ministry of Transport Type Approval Ref. FMT/99/K4M).
The Renault K4M 701 is a 1,598 cc inline‑four naturally aspirated petrol engineered for compact and mid-size vehicles (1999-2008). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver responsive mid-range torque and urban efficiency. Designed to meet Euro 3 emissions standards, it prioritises serviceability and cost-effective ownership.

The DOHC 16-valve design provides smooth power delivery ideal for highway cruising but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. SAE 5W-40 semi-synthetic oil is critical for camshaft lobe protection, especially on the exhaust side. The relatively high compression ratio demands good fuel quality (95 RON minimum). The Siemens injection system is generally robust but requires clean fuel and periodic injector cleaning. High-mileage engines should have camshaft lobes inspected per Renault TB-K4M-05.
Oil Specs: Requires SAE 5W-40 semi-synthetic oil specification (Renault Workshop Manual 7700). Mineral oils are not recommended for extended service.
Emissions: Euro 3 certification applies to all 1999-2008 models (French Ministry of Transport Type Approval Ref. FMT/99/K4M).
Power Ratings: Measured under CEE/ECE standards (Renault Group PT-2003). Output is net power at the flywheel.

The Renault K4M 701 was used across Renault's C-segment platforms with transverse mounting. This engine received platform-specific adaptations-standard fitment in the Mégane II and Scénic II-with no major facelift revisions affecting core components, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a machined pad on the front face of the cylinder block, near the gearbox flange (Renault Workshop Manual 7700). The full designation 'K4M 701' should be clearly visible. Differentiation from the similar K4M 700 (used in earlier Mégane models) is primarily by the 16-valve cylinder head and specific ECU mapping. The timing belt cover and intake manifold are visually distinct from 8-valve variants. Engine ancillaries (alternator, starter) are generally interchangeable within the K4M family.
The K4M 701's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in high-mileage or poorly maintained examples. Renault service data indicates camshaft wear is a common cause of performance loss after 150,000 km, while general mechanical robustness is otherwise good. Infrequent oil changes and use of incorrect oil can accelerate wear on cam lobes and hydraulic lifters.
