The Renault N7Q 710 is a 2,188 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2008. Developed from the F — Type engine family, it features a dual overhead camshaft (DOHC) layout and 16‑valve configuration. Output is rated at 103 kW (140 PS), with torque of 200 Nm delivered at 3,750 rpm, providing linear power delivery suited to relaxed highway cruising and urban driving.
Fitted to models including the Laguna II, Espace III, and Avantime, the N7Q…
All production years (2001–2008) meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/3456).
The Renault N7Q 710 is a 2,188 cc inline‑four naturally aspirated petrol engine engineered for mid‑size and large passenger vehicles (2001–2008). It combines sequential multi‑point fuel injection with a DOHC 16‑valve head to deliver smooth, linear power delivery and refined highway cruising. Designed to meet Euro 3 emissions standards, it prioritizes drivability and mechanical simplicity over high output.

The Renault N7Q 710 was used across Renault's Laguna II, Espace III, and Avantime platforms with transverse mounting. This engine received platform-specific adaptations—reinforced engine mounts in the Espace and revised intake manifolds in the Avantime—and all variants retained Euro 3 compliance throughout production. No licensing partnerships existed for this engine. All adaptations are documented in OEM technical bulletins.
The N7Q 710's primary reliability risk is timing belt tensioner pulley wear, with elevated incidence in vehicles exceeding the 120,000 km or 5-year service interval. Renault internal service data (2006) indicated up to 12% of pre-2004 engines required premature belt system replacement due to pulley seizure, while UK DVSA MOT records show EGR-related rough idle as a common drivability complaint in high-mileage examples. Infrequent maintenance accelerates wear, making adherence to service intervals critical.
Analysis derived from Renault technical bulletins (2001–2008) and UK DVSA failure statistics (2010–2023). 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 N7Q 710 offers smooth, refined performance with mechanical simplicity, but early models (2001–2003) are prone to timing belt tensioner wear. Later revisions (2004+) improved component durability. Strict adherence to the 120,000 km or 5-year timing belt interval and regular oil changes greatly extend engine life.
Top issues include timing belt tensioner pulley wear, EGR valve clogging, ignition coil failure, and oil leaks from cam/sump gaskets. These are well-documented in Renault service bulletin RNT/2005/03, especially in high-mileage or poorly maintained vehicles.
The N7Q 710 powered the Laguna II, Espace III, and Avantime from 2001–2008. All variants are 2.2L naturally aspirated petrol engines producing 140 PS and meeting Euro 3 emissions standards.
Limited potential. The naturally aspirated design and conservative compression ratio restrict gains. Mild tuning (intake/exhaust, ECU remap) may yield +8–12 kW, but significant power increases require forced induction, which is complex and uncommon for this engine.
In a Laguna II 2.2, expect ~10.5 L/100km (city) and ~6.8 L/100km (highway), or ~33 mpg UK combined. Real-world mixed driving typically returns 28–35 mpg (UK), depending on model, driving style, and maintenance condition.
Yes. The N7Q series is an interference engine. If the timing belt fails, piston-to-valve contact can cause catastrophic damage. This makes strict adherence to the 120,000 km or 5-year replacement interval essential.
Renault specifies 10W-40 mineral or semi-synthetic oil meeting RN0700 standard. Change every 15,000 km or 12 months—whichever comes first—to maintain valve train and bearing protection.
