The Renault Z7V 711 is a 2,946 cc V6 naturally aspirated petrol engine engineered for executive sedans and premium MPVs (1996–2002). It combines DOHC valvetrain with sequential multi‑point injection to deliver smooth high‑rpm power and refined highway cruising. Designed to meet Euro 2 standards, it balances performance with emissions compliance.

The Renault Z7V 711 was used across Renault's executive and premium MPV platforms with longitudinal mounting. This engine received platform-specific adaptations—reinforced subframes in the Espace III and revised exhaust manifolds in the Laguna I—and from 1999 the aluminium thermostat housing, creating 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 Z7V 711 offers smooth V6 performance and refined operation, but early models (1996–1998) had thermostat housing coolant leak concerns. Later revisions (post-1999) eliminated this issue with an aluminium housing. Regular oil changes with RN0700 oil and timely cooling system maintenance greatly enhance longevity.
Top issues include coolant leaks from the early plastic thermostat housing, timing chain tensioner wear, ignition coil pack failure, and intake manifold gasket leaks. These are well-documented in Renault service bulletins 05 03 08 and 05 06 12, particularly in high-mileage executive vehicles.
This 3.0L V6 powered the Renault Laguna I (1996–2001), Safrane (1996–2000), and Espace III (1996–2002). All applications are Euro 2-compliant executive sedans and premium MPVs with longitudinal engine mounting.
Aftermarket ECU tuning is common on the Z7V-711 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 Renault Laguna 3.0 V6, real-world consumption is ~12.5 L/100km (urban) and ~8.2 L/100km (highway), or about 23 mpg UK combined. Fuel economy varies with load and driving style; expect 20–26 mpg UK in mixed use.
Yes. The Z7V series uses an interference design. If either timing chain fails or jumps, piston-to-valve contact can cause internal damage. However, the dual front-mounted chains are generally robust with proper maintenance.
Renault specifies 10W-40 mineral or semi-synthetic oil meeting RN0700 standard. Always use OEM-approved oil and change every 15,000 km or annually to protect timing chains and camshafts from wear.
