The Renault Z7W 717 is a 2,963 cc, V6 naturally aspirated petrol engine produced between 1996 and 2003. It features a DOHC 24‑valve layout and sequential multi‑point fuel injection. In standard form it delivers 155 kW (211 PS) and 285 Nm of torque, with smooth power delivery and refined high‑rpm character.
Fitted primarily to the Laguna I Phase 2 and Avantime, the Z7W 717 was engineered for spirited highway cruising, responsive mid‑range performance, and compliance with E…
Production years 1996–2003 meet Euro 3 standards .
The Renault Z7W 717 is a 2,963 cc V6 naturally aspirated petrol engine engineered for premium hatchbacks and coupés (1996–2003). It combines sequential multi-point fuel injection with dual overhead camshafts to deliver linear, high-revving performance and refined motorway cruising. Designed to meet Euro 3 emissions standards, it balances responsiveness with drivability.

The Renault Z7W 717 was used across Renault's premium hatchback and coupé platforms with transverse mounting. This engine received platform-specific adaptations—reinforced engine mounts in the Avantime and revised intake manifolds in the Laguna I Phase 2—and from 2001 the updated timing system introduced minor service part interchange limits. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Z7W 717 is generally robust when maintained properly, but early units (1996–2000) are prone to timing belt tensioner bearing failure if service intervals are exceeded. Later models (2001–2003) feature updated pulleys and improved durability. Using correct oil (RN0700) and 95 RON petrol, plus adhering to 60,000 km timing belt changes, greatly improves longevity.
Top issues include timing belt tensioner wear, catalytic converter degradation, intake manifold gasket leaks, and ignition coil pack failure. These are documented in Renault Technical Notes TN‑ME‑1999‑07 and service bulletins. Fuel quality and maintenance discipline significantly influence reliability.
The Z7W 717 powered the Laguna I Phase 2 (1999–2003) and Avantime (2001–2003) as the 3.0 V6. It was not used in Nissan or other alliance brands. All feature Euro 3 compliance with three-way catalytic converters.
Aftermarket ECU tuning is common on the Z7W-717 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Laguna I Phase 2 3.0 V6, real-world consumption is ~11.5 L/100km (city) and ~7.6 L/100km (highway), or ~24 mpg UK combined. The Avantime averages 12.0–12.8 L/100km (22–23 mpg UK) due to its aerodynamic profile and weight.
Yes. The Z7W series uses an interference design. If the timing belt fails or jumps, piston-to-valve contact can cause catastrophic damage. Strict adherence to 60,000 km or 48-month belt replacement is critical to prevent engine destruction.
Renault specifies RN0700 (10W‑40, ACEA A3/B3) mineral or semi-synthetic oil. This protects the DOHC valvetrain and prevents sludge. Change every 15,000 km or 12 months—whichever comes first—to maintain reliability.
