The Renault F2N 752 is a 1,596 cc, inline‑four diesel engine produced between 1985 and 1996. It features a single overhead camshaft (SOHC) with two valves per cylinder and indirect injection via a Bosch mechanical fuel pump. This naturally aspirated unit delivers 43 kW (58 PS) and 105 Nm of torque, prioritising durability and fuel economy over performance.
Fitted to models such as the R9, R11, and Express van, the F2N 752 was engineered for economical, low — maintenance tran…
Production years 1985–1996 meet pre-Euro emissions standards .
The Renault F2N 752 is a 1,596 cc inline‑four diesel engine engineered for compact cars and light vans (1985-1996). It combines a simple SOHC 8-valve design with indirect injection to deliver rugged reliability and excellent fuel economy. Designed for pre-Euro standards, it prioritises low running costs and ease of repair.

The Renault F2N 752 was used across Renault's compact platforms with transverse mounting. This engine received no major platform-specific adaptations during its production run, ensuring broad parts interchangeability. All applications 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.
The F2N 752's primary reliability risk is cylinder head gasket failure, with elevated incidence in vehicles used for towing or in hot climates. Renault service data indicates a correlation between neglected coolant changes and head gasket failure. Secondary to this, timing belt failure remains a critical concern if replacement intervals are ignored.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F2N 752 is renowned for its mechanical simplicity and ruggedness. Its long-term reliability is excellent if the timing belt is replaced on schedule and the cooling system is meticulously maintained to prevent head gasket failure. With proper care, these engines can easily surpass 300,000 km.
The most critical issue is cylinder head gasket failure, often due to overheating or old coolant. Other common problems include timing belt failure if neglected, worn glow plugs causing cold-start issues, and leaking seals on the Bosch injection pump. These are well-documented in Renault service information.
The F2N 752 was used in the Renault R9 (1985-1989), R11 (1985-1989), and the Renault Express van (1986-1996). It was not used in vehicles from other manufacturers.
Significant power gains are not practical due to the engine's indirect injection and low-compression design for its era. Minor improvements might be possible by adjusting the injection pump, but this risks reliability and fuel economy. It's best appreciated for its original, economical, and durable character.
Excellent for its time. In a Renault R9, expect real-world figures of approximately 5.7 L/100km (city) and 4.7 L/100km (highway), translating to roughly 50 mpg UK combined. Its efficiency made it a popular choice for budget-conscious drivers and fleet operators.
Yes. The F2N 752 is an interference engine. If the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal damage. This makes the 80,000 km timing belt replacement interval absolutely critical.
Renault specifies RN0700 15W-40 mineral oil. Using the correct specification is vital for engine longevity. The oil should be changed every 10,000 km or 12 months. Using a thinner or incorrect oil can lead to increased wear, especially under load.
