The Renault J7R 760 is a 2,165 cc, inline‑six petrol engine produced between 1984 and 1996. It features a cast-iron block, an aluminium cylinder head with a single overhead camshaft (SOHC), and multi-point fuel injection. In standard form, it delivered approximately 94 kW (128 PS), offering smooth, linear power delivery for Renault's executive vehicles.
Fitted primarily to the Renault 25 TS and Baccara models, the J7R 760 was engineered for refined, quiet cruising and long-distance comfort. Emissions compliance for its era was managed through a three-way catalytic converter and electronic engine management, meeting applicable French and European standards of the late 1980s and early 1990s.
One documented area for attention is premature failure of the water pump, which can lead to engine overheating. This issue is referenced in Renault Technical Note 4456E and is often linked to the use of incorrect coolant or extended service intervals, leading to corrosion and bearing wear within the pump assembly.
Production years 1984–1996 meet applicable French and European emissions standards for passenger vehicles of that era (no centralized VCA-type approval existed for this period).
The Renault J7R 760 is a 2,165 cc inline‑six petrol engine engineered for executive sedans (1984-1996). It combines multi-point fuel injection with a single overhead camshaft to deliver smooth, linear power and refined operation. Designed for its era, it prioritizes durability and comfort over modern emissions or fuel economy targets.

The inline-six configuration provides exceptionally smooth operation ideal for highway cruising but requires strict adherence to 15,000 km or 12-month coolant and oil change intervals to protect the water pump and engine internals. The Bosch LE Jetronic system demands periodic inspection of sensors and injectors for optimal performance. Service campaign 4456E provides updated water pump parts for affected vehicles to mitigate premature failure.
Oil Specs: Requires SAE 10W-40 mineral oil for optimal performance in original equipment (Renault Owner's Manual 1990). Modern semi-synthetics may be used if compatible with older seals.
Emissions: Compliance was with decentralized national standards; no unified Euro standard existed. Documentation is per Renault Engineering Spec. #J7R-EM.
Power Ratings: Measured under SAE J1349 standards. Output figures are for standard calibration (Renault TIS Doc. J7R-003).

The Renault J7R 760 was used exclusively in Renault's R25 platform with longitudinal mounting. This engine received minor platform-specific adaptations-reinforced engine mounts for the heavier Baccara variant-but no major revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the left side of the engine block, near the rear of the cylinder head (Renault TIS J7R-005). The engine is visually identifiable by its long, inline-six configuration, single overhead camshaft cover, and the presence of a multi-point fuel injection rail on the intake manifold. Critical differentiation from the carburetted J6R: J7R 760 has six fuel injectors and associated wiring harnesses. Service parts, particularly for the fuel and ignition systems, are not interchangeable with carburetted variants.
The J7R 760's primary reliability concern is failure of the water pump, with elevated incidence in vehicles subjected to extended coolant change intervals or using incorrect coolant. Renault Technical Note 4456E documents this issue, while owner reports frequently cite issues with the aging Bosch LE Jetronic fuel injection system. Adhering to the specified maintenance schedule is critical for long-term reliability.
