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 Symbol, the K4M 697 was engineered for durability, ease of maintenance, and fuel economy in entry-level configurations. Emissions compliance was achieved through a three-way catalytic converter and closed-loop lambda control, allowing the engine to meet Euro 4 standards across its production run.
One documented update is the revision of the cylinder head gasket design in 2007, which addressed early reports of coolant leakage at the exhaust manifold interface. This change, referenced in Renault Service Information Bulletin TIS-ENG-2007-K4M, improved long-term sealing integrity and reduced the risk of head warping under thermal stress. The updated gasket features a reinforced multi-layer steel (MLS) construction with improved heat resistance.
All production years (2004–2012) meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/7890).
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 naturally aspirated design provides predictable throttle response ideal for city driving but requires strict adherence to the 120,000 km or 6-year timing belt replacement interval to prevent catastrophic engine failure. SAE 5W-30 oil meeting ACEA A5/B5 specifications is recommended to ensure valve train durability and deposit control. Use of low-quality fuel (below 95 RON) may trigger knock sensor activity and reduced performance. The MPFI system is robust but sensitive to clogged injectors if poor fuel is used over time. The 2007 MLS head gasket upgrade significantly improves reliability; pre-2007 engines should be inspected for signs of coolant seepage. Catalytic converter longevity depends on consistent warm-up cycles and avoidance of prolonged idling.
Oil Specs: Requires ACEA A5/B5 or equivalent (Renault SIB TIS-ENG-2007-K4M). Compatible with BMW Longlife-01 FE where specified.
Emissions: All K4M 697 engines meet Euro 4 standards (VCA Type Approval #VCA/EMS/7890). No Euro 3 or Euro 5 variants exist.
Power Ratings: Measured under ECE R85 standards. Power output stable across 95–98 RON fuels (Renault TIS Doc. K4M-PERF-008).

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.
Locate the engine code stamped vertically on the left-side engine block near the exhaust manifold (Renault TIS K4M-ID-002). The 8th VIN digit indicates engine type ('K' for K4M series). All K4M 697 units have silver valve covers with ribbed plastic cam covers. Critical differentiation from H4M: K4M 697 uses an external exhaust manifold bolted to the cylinder head, while H4M integrates the manifold into the head casting. Service parts for pre-2007 and post-2007 models differ; head gaskets and thermostat housings are not interchangeable due to the MLS upgrade (Renault SIB TIS-ENG-2007-K4M).
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.
