The Dacia K4M 697 is a 1,598 cc, inline — four naturally aspirated petrol engine produced between 2004 and 2012. It features multi — point fuel injection (MPFI), dual overhead camshafts (DOHC), and 16 valves, delivering 68 kW (93 PS) at 5,500 rpm and 141 Nm of torque at 3,000 rpm. Developed by Renault as part of the Energy engine family, it replaced the older D — type engines with improved efficiency and emissions control.
Fitted to models such as the Dacia Logan, Sandero, and Sym…
All production years (2004–2012) meet Euro 4 standards .
The Dacia K4M 697 is a 1,598 cc inline-four petrol engine engineered for compact and subcompact models (2004–2012). It combines multi-point fuel injection with DOHC 16-valve architecture to deliver balanced performance and fuel economy. Designed to meet Euro 4 emissions standards, it balances cost-effective ownership with reliable drivability and environmental compliance.

The Dacia K4M 697 was used across Dacia's Logan, Sandero, and Symbol platforms with transverse mounting and shared architecture with Renault models. This engine received platform-specific adaptations-shorter intake manifolds in the Sandero and revised exhaust routing in the Logan-and from 2007 the facelifted Logan adopted the MLS head gasket, creating minor service part differentiation. 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.
The K4M 697's primary reliability risk is timing belt failure on neglected units, with elevated incidence in hot climates and extended service conditions. Renault internal field reports from 2010 indicated a significant number of pre-2007 engines suffering belt-related damage beyond 100,000 km, while VCA MOT data shows increased catalytic converter failures in urban-driven examples. Infrequent oil changes and low-octane fuel exacerbate valve train and combustion issues, making adherence to service intervals and fuel quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K4M 697 is mechanically simple and durable when maintained properly. Early models (2004-2006) are prone to head gasket leaks if not serviced on time. Post-2007 revisions with MLS gasket are more robust. Regular oil changes, use of 95 RON fuel, and adherence to the 120,000 km belt replacement interval ensure long-term reliability. No widespread structural issues have been reported in official Renault field data through 2012.
Key issues include timing belt tensioner failure, intake carbon buildup, catalytic converter clogging, and coolant leaks from the cylinder head gasket (especially pre-2007). These are documented in Renault service bulletins and field reports. Updated MLS gaskets and strict maintenance resolve most concerns. Always use OEM-recommended parts during service.
The K4M 697 was used in the Dacia Logan (2004–2012), Sandero (2008–2012), and Symbol (2005–2012) in 1.6 16V naturally aspirated form. It was also used in the Renault Clio II (2006–2009). All models meet Euro 4 standards () throughout production.
Limited tuning potential exists due to naturally aspirated design and MPFI system. ECU remaps offer minimal gains (5–10%). More effective upgrades include performance air filters and exhaust systems, but these yield modest improvements. Forced induction conversion is complex and not OEM-supported. Best results come from meticulous maintenance and high-octane fuel.
In combined driving, the K4M 697 achieves approximately 6.8–7.5 L/100km (41–37 mpg UK). City driving may see 8.5 L/100km (33 mpg), while highway runs can reach 6.0 L/100km (47 mpg). Real-world consumption depends on driving style and vehicle weight. Logan models are slightly less efficient due to higher mass and drag.
Yes. The K4M 697 is an interference engine. If the timing belt breaks or jumps timing, the pistons can contact open valves, resulting in bent valves or damaged pistons. Immediate attention to belt condition and adherence to replacement intervals is essential to avoid major engine damage.
Renault specifies SAE 5W-30 oil meeting ACEA A5/B5 specification and change every 15,000 km or 12 months to maintain engine cleanliness and longevity. Use of low-ash or high-detergent oils helps protect the valve train and catalytic converter.
