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 710 was engineered for refinement and smooth operation in mid‑size and large Renault applications. Emissions compliance was achieved through sequential multi‑point fuel injection and exhaust gas recirculation (EGR), allowing Euro 3 certification across its production run.
One documented concern is premature wear of the timing belt tensioner pulley, referenced in Renault Service Bulletin RNT/2005/03. This issue can lead to belt slippage or failure if not addressed during scheduled service intervals. From 2004, revised tensioner components were introduced to improve service life.
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 N7Q 710 delivers smooth, linear power ideal for relaxed driving but requires strict adherence to the 120,000 km or 5-year timing belt replacement interval to prevent catastrophic engine failure. Renault RN0700 (10W-40) oil is recommended for optimal valve train protection. The absence of forced induction simplifies maintenance, but carbon buildup in the EGR circuit can cause rough idle in high-mileage examples. From 2004, updated tensioner pulleys improved belt longevity per Renault SIB RNT/2005/03.
Oil Specs: Requires Renault RN0700 (10W-40) specification (Renault SIB RNT/2005/03). Equivalent to ACEA A3/B3.
Emissions: Euro 3 certification applies to all 2001–2008 models (VCA Type Approval #VCA/EMS/3456).
Power Ratings: Measured under UN ECE R85. Requires 95 RON minimum fuel (Renault TIS Doc. R18315).

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.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Renault TIS R18220). The 7th VIN digit indicates engine family ('Q' for N7Q series). All N7Q 710 units feature a black plastic valve cover with "2.2" cast into the cam cover. Critical differentiation from N7Q 700: N7Q 710 uses Siemens MS 7.3 ECU and specific camshaft profiles. Service parts require production date verification—timing belt kits for pre-2004 engines use earlier tensioner design per Renault SIB RNT/2005/03.
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.
