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.

Production years 1999–2005 meet Euro 3 standards; 2006–2008 models may have Euro 4 compliance depending on market .
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 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.
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.
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.
Analysis derived from Renault technical bulletins (1999-2008) and historical workshop manuals. 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 700 is generally reliable if its critical maintenance points are addressed: strict adherence to the 60,000 km timing belt replacement and periodic inspection of the exhaust manifold for cracks. With proper maintenance, these engines can easily exceed 200,000 km. Neglecting either of these points will almost certainly lead to expensive repairs.
The most critical issue is exhaust manifold cracking near the cylinder head flange. Timing belt failure due to neglected replacement is also common. Other frequent problems include ignition coil pack failures causing misfires and coolant leaks from the plastic thermostat housing.
The K4M 700 engine was fitted to the Renault Clio II (1999-2005), Mégane II (2002-2008), and Scénic I (1999-2003) in their 1.6 16V variants. It was the primary 1.6L petrol engine for these platforms during its production run.
Minor power gains are possible through ECU remapping or intake/exhaust modifications, typically adding 5-10 kW. The engine's bottom end is robust, but pushing it significantly offers diminishing returns. Conservative tuning is advised to maintain reliability.
Fuel economy is respectable for its size. Expect real-world figures of approximately 7.0-8.0 L/100km (35-40 mpg UK) on a mixed cycle in a Clio or Mégane. Its efficiency makes it a good choice for mixed driving conditions.
No. The K4M 700 is a non-interference engine. If the timing belt snaps, the pistons will not contact the valves, preventing catastrophic internal damage. This is a significant safety feature, though ancillary damage can still occur.
Renault specifies a semi-synthetic 10W-40 engine oil meeting ACEA A3/B3 standards. Change intervals should be kept to 15,000 km or annually. Using the correct oil helps maintain engine longevity.
