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.

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 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.
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.
Analysis derived from Renault technical bulletins (2001-2006) and owner-reported failure patterns. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The G8T 752 is a robust and torquey engine with a simple indirect injection system. Its main weaknesses are the dual-mass flywheel and the timing belt. With proactive maintenance—especially timely belt changes and using quality oil—it can be very dependable for high-mileage use.
The most critical issues are dual-mass flywheel failure causing drivetrain vibration, and timing belt failure leading to engine damage. Other common problems include Bosch VP44 injection pump failure and turbocharger oil seal leaks. These are well-documented in Renault's service information.
The G8T 752 was primarily used in the second-generation Renault Laguna (2001-2005) in dCi 115 and dCi 127 variants. It was also fitted to the third-generation Renault Espace (2002-2006) in the dCi 115 specification.
Aftermarket ECU tuning is common on the G8T-752 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.
Real-world fuel economy varies by model and driving style. In a Laguna dCi 115, expect around 7.0 L/100km (40 mpg UK) combined. The heavier Espace dCi 115 might return 8.5 L/100km (33 mpg UK). Highway driving can yield figures closer to 5.5 L/100km (51 mpg UK).
Yes. The G8T 752 is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing catastrophic internal damage. This makes adhering to the 90,000 km replacement interval absolutely critical.
Renault recommends RN0700 specification oil, typically a 10W-40 semi-synthetic or mineral oil. This is suitable for the engine's design and operating temperatures. Using a quality oil and changing it regularly is key to longevity, especially for the turbocharger and injection pump.
