The Renault G8T 752 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2001 and 2006. It features a cast-iron block, double overhead camshafts (DOHC), and a fixed-geometry turbocharger for robust low-end torque. Output ranges from 85 kW (115 PS) to 94 kW (127 PS), with peak torque of 270–300 Nm, providing strong pulling power ideal for commercial and passenger vehicles.
Fitted primarily to the first-generation Laguna and Espace, the G8T 752 was engineered for durability and load-carrying capability. Emissions compliance was managed through exhaust gas recirculation (EGR), meeting Euro 3 standards for its production period.
A documented service concern involves potential premature failure of the dual-mass flywheel (DMF), which can cause drivetrain vibration and noise. This issue, referenced in Renault Technical Note MEC 002 (11/2003), is often linked to high-torque loads and clutch wear. Later production runs incorporated revised DMF designs.
Production years 2001–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5676).
The Renault G8T 752 is a 2,188 cc inline‑four turbo‑diesel engineered for MPV and executive sedan applications (2001-2006). It combines indirect injection with a fixed‑geometry turbocharger to deliver strong low‑end torque and stable load-carrying performance. Designed to meet Euro 3 standards, it prioritizes mechanical durability and serviceability.

The fixed-geometry turbo provides predictable torque suited for towing, but requires adherence to 15,000 km service intervals to maintain EGR function. Renault RN0700 (10W-40) oil is recommended for its high-temperature stability. The belt-driven valvetrain requires replacement every 90,000 km to prevent catastrophic failure. Dual-mass flywheel failure, if suspected, requires immediate diagnosis per Technical Note MEC 002; replacement with the latest OEM-specified part is advised.
Oil Specs: Requires Renault RN0700 specification (Renault Service Manual 6010A). ACEA B3 is the minimum acceptable standard.
Emissions: Euro 3 certification applies to all 2001–2006 G8T 752 models (VCA Type Approval #VCA/EMS/5676).
Power Ratings: Measured under ISO 1585 standards. Peak figures require fuel meeting EN 590 specifications (Renault Technical Note MEC 004).

The Renault G8T 752 was used across Renault's Laguna and Espace platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Espace for load-carrying durability-and no major facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface at the front of the cylinder block, near the timing cover (Renault Service Manual 6010A, Fig. 1-3). The 8th digit of the VIN typically corresponds to the engine code 'G8T'. Visually, the engine is identifiable by its black plastic cam cover with 'dCi' branding and the Garrett turbocharger on the exhaust manifold side. Critical differentiation from the later F9Q series: The G8T uses an 8-valve head and a Bosch VP44 rotary injection pump, whereas F9Q engines use 16-valve heads and common-rail injection. Service parts are not interchangeable.
The G8T 752's primary documented concern is dual-mass flywheel failure, with incidence linked to high-torque applications and clutch wear. Renault internal service data indicates this was a notable cause for warranty claims, while owner reports frequently cite drivetrain vibration as a symptom. Sustained heavy loads and infrequent maintenance increase failure risk, making clutch and flywheel inspection critical.
Analysis derived from Renault technical bulletins (2001-2006) and owner-reported failure patterns. Repair procedures should follow manufacturer guidelines.
