The Renault G8T 760 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 1999 and 2005. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a fixed‑geometry turbocharger. Power output ranged from 85 kW (115 PS) to 94 kW (128 PS), with torque figures between 270–300 Nm, providing strong pulling power for its class.
Fitted primarily to the Laguna II and Espace IV platforms, including variants like the 2.2 dCi 115 and 2.2 dCi 128, the G8T 760 was engineered for a blend of fuel economy and responsive performance in mid-size applications. Emissions compliance for most units was achieved through exhaust gas recirculation (EGR), meeting Euro 3 standards.
One documented reliability concern involves premature failure of the vacuum-operated turbocharger wastegate actuator, which can lead to boost control issues. This issue, referenced in Renault Technical Note LAG‑01‑02, is often linked to diaphragm degradation or linkage corrosion. Later revisions incorporated minor updates to the actuator's internal seals and linkage material.
Production years 1999–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5682).
The Renault G8T 760 is a 2,188 cc inline‑four turbo‑diesel engineered for mid-size sedans and MPVs (1999-2005). It combines a Bosch VP44 rotary injection pump with a single fixed‑geometry turbocharger to deliver strong low-end torque and efficient highway cruising. Designed to meet Euro 3 standards, it prioritizes drivability and economy for its era.

The fixed-geometry turbo provides predictable boost but requires strict 60,000 km timing belt changes to prevent catastrophic failure. Renault RN0700 (10W-40) oil is recommended for injector pump longevity. Extended idling should be avoided to prevent EGR valve coking. The Bosch VP44 pump is sensitive to water and low-quality fuel; always use EN 590 standard diesel. The vacuum-operated wastegate actuator is prone to diaphragm failure per Renault Note LAG-01-02; inspect linkage for free movement during service. EGR systems require cleaning every 80,000 km to maintain performance.
Oil Specs: Requires Renault RN0700 specification (Renault Technical Note LAG-01-02). Equivalent to ACEA B3.
Emissions: Euro 3 certification applies to all 1999-2005 G8T 760 models (VCA Type Approval #VCA/EMS/5682).
Power Ratings: Measured under SAE J1349 standards. 94 kW output requires EN 590 fuel quality (Renault Group PT-2003).

The Renault G8T 760 was used across Renault's Laguna II and Espace IV platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Espace's raised ride height-and no significant facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, below the exhaust manifold (Renault Service Manual 2.2 dCi). The 8th VIN digit typically indicates engine power output ('E' for 115 PS, 'F' for 128 PS). All G8T 760 engines feature a black plastic cam cover with 'dCi' branding. Critical differentiation from the later G9T: The 760 uses a Bosch VP44 rotary injection pump and a fixed-geometry turbo, while the G9T uses common-rail injection and a VGT turbo. Fuel pumps and turbochargers are specific to the G8T 760 variant and not interchangeable with other G8T/G9T codes without major modification.
The G8T 760's primary reliability risk is timing belt failure, with elevated incidence in vehicles with neglected service intervals. Renault internal reports indicated a significant correlation between belt failures and extended mileage, while owner data suggests turbo actuator faults are common. Using low-quality fuel or skipping filter changes makes preventative maintenance critical.
