The Dacia K7J 710 is a 1,390 cc, inline — four petrol engine produced between 2008 and 2013. It forms part of the Renault — Nissan — Dacia shared powertrain family, designed for affordability and ease of maintenance. Featuring a single overhead camshaft (SOHC), multi — point fuel injection (MPi), and 8 — valve architecture, it delivers 59 kW (80 PS) at 5,500 rpm and 118 Nm of torque at 3,250 rpm.
Fitted to core models such as the Dacia Sandero and Logan, the K7J 710 was engineered fo…
Production years 2008–2009 meet Euro 4 standards; 2010–2013 models maintain Euro 4 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Dacia K7J 710 is a 1,390 cc inline-four petrol engine engineered for entry-level hatchbacks and sedans (2008–2013). It combines multi-point fuel injection with a single overhead camshaft to deliver predictable performance and low running costs. Designed to meet Euro 4 standards, it balances urban drivability with mechanical simplicity.

The Dacia K7J 710 was used across Dacia's Logan/Sandero platforms with transverse mounting and shared architecture with Renault and Nissan for global applications. This engine received platform-specific adaptations-shortened intake manifolds in the Sandero and revised exhaust routing in the Logan-and from 2010 the facelifted Logan II introduced minor ECU recalibrations, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
The K7J 710's primary reliability risk is camshaft wear on early builds, with elevated incidence in high-temperature climates. Internal Renault quality reports from 2011 noted increased warranty claims for camshaft replacement in Southern European and North African markets, while UK DVSA data shows timing belt neglect as a leading cause of engine failure in imported units. Extended oil intervals and low-octane fuel exacerbate wear, making maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K7J 710 is generally reliable when maintained properly, but early models (2008–2009) showed increased camshaft wear in hot climates. Later revisions (post-2010) improved durability with better surface treatments. Regular oil changes (every 15,000 km) and strict adherence to the 120,000 km timing belt interval are essential for longevity.
The most documented issues are camshaft wear (especially pre-2010), timing belt failure due to neglect, idle instability from throttle body carbon buildup, and coolant leaks from the thermostat housing. These are covered in Renault service bulletins and field reports from European and African markets.
The K7J 710 was used in the Dacia Logan (2008–2013) and Sandero (2008–2012), both badged as 1.4 MPI (80 PS). It was also shared with the Renault Clio III and Nissan Micra K13. All models meet Euro 4 emissions standards and use transverse front-wheel-drive layouts.
Limited tuning potential exists. ECU remaps offer minor gains (~5–10%) but are constrained by the 8-valve SOHC design. Aftermarket options include performance air filters and exhausts, but significant power increases require internal modifications. Most owners prioritise reliability over performance upgrades.
In combined driving, the K7J 710 achieves approximately 6.5 L/100km (43 mpg UK) in the Sandero and 7.0 L/100km (40 mpg UK) in the Logan. Highway efficiency improves to ~5.8 L/100km (49 mpg UK). Real-world figures vary with load and terrain, but it remains a frugal choice for budget-conscious drivers.
Yes. The K7J 710 is an interference engine. If the timing belt breaks or jumps, the pistons can collide with open valves, causing severe internal damage. This makes strict adherence to the 120,000 km replacement interval absolutely critical to avoid costly repairs.
The engine requires SAE 5W-30 oil meeting ACEA A1/B1 or A5/B5 specifications. High-quality synthetic or semi-synthetic oils are recommended, especially in hot climates. Oil changes should be performed every 15,000 km or 12 months to protect the camshaft and ensure reliable operation.
