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.

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 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.
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.
Analysis derived from Renault technical bulletins (1999-2008) and aggregated European repair workshop data (2001-2015). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The K4M 701 is generally reliable with proper maintenance. Its main weakness is potential exhaust camshaft lobe wear, which is preventable with timely oil changes using the correct 5W-40 semi-synthetic oil. With adherence to the 60,000 km timing belt replacement schedule, these engines can reliably reach 200,000 km or more without major issues.
The most frequent issues are exhaust camshaft lobe wear, leading to power loss, and timing belt failure if neglected. Coolant temperature sensor faults and valve cover gasket leaks are also common on high-mileage examples, as documented in Renault service bulletins.
The K4M 701 engine was used in the second-generation Renault Mégane (BM0/1), second-generation Scénic (JM0/1), and second-generation Laguna (BG0/1) during the 2001-2008 period. It was the 1.6-litre 16-valve petrol option for these popular models.
Minor power gains are possible through ECU remapping, high-flow air filters, and performance exhaust systems, potentially yielding 10-15 additional PS. Significant tuning is limited by the engine's internal components and is not commonly supported. Reliability may be compromised without supporting modifications.
Fuel economy is respectable for its era and size. In a Renault Mégane 1.6 16V, expect real-world figures of approximately 7.5-8.5 L/100km (33-38 mpg UK) on a mixed cycle. Careful highway driving can achieve figures closer to 6.5 L/100km (43 mpg UK), reflecting its efficient design.
Yes. The K4M 701 is an interference engine. If the timing belt were to fail, the pistons and valves would collide, causing severe internal engine damage. This makes strict adherence to the 60,000 km replacement interval absolutely critical.
Renault specified a high-quality semi-synthetic oil, typically SAE 5W-40, meeting ACEA A3/B3 or equivalent standards. Using the correct viscosity is crucial for protecting the camshafts and hydraulic lifters from premature wear, especially on the exhaust side.
