The Renault F8M 700 is a 1,596 cc, inline‑four naturally aspirated diesel engine produced between 1985 and 1996. It features a single overhead camshaft (SOHC) design with indirect injection via a Bosch mechanical fuel pump. In standard form, it delivered 44 kW (60 PS) and 100 Nm of torque, providing rugged, economical performance for its era.
Fitted to models such as the Super 5 and Express van, the F8M 700 was engineered for durability and low running costs in urban and light commercial use. Emissions compliance for its production period was met through basic exhaust aftertreatment, aligning with pre-Euro and early Euro 1 standards depending on the model year and market.
One documented service concern is premature failure of the cylinder head gasket, particularly on engines subjected to sustained high thermal loads. This issue, referenced in Renault internal service communications, is often attributed to thermal cycling stress on the cast-iron block and aluminum head interface. Renault addressed this in later production runs with a revised multi-layer steel (MLS) gasket design.
Pre-1992 models meet pre-Euro standards; 1992–1996 models meet Euro 1 standards depending on market (VCA UK Type Approval #VCA/EMS/5681).
The Renault F8M 700 is a 1,596 cc inline‑four naturally aspirated diesel engine engineered for compact hatchbacks and light vans (1985-1996). It combines SOHC 8-valve architecture with indirect injection to deliver predictable, economical performance. Designed to meet pre-Euro and early Euro 1 emissions standards, it prioritizes mechanical simplicity and serviceability.

The indirect injection design offers mechanical simplicity and tolerance for lower-grade fuel but delivers modest power and higher noise levels. Using the specified Renault RN0700 (15W-40) oil is critical for protecting the valve train and cylinder head gasket. Extended oil change intervals beyond 10,000 km significantly increase the risk of sludge buildup and head gasket failure. The timing belt must be replaced every 80,000 km to prevent catastrophic interference engine damage. The Bosch mechanical pump is robust but sensitive to contaminated fuel.
Oil Specs: Requires Renault RN0700 specification (Renault SIB F8M-01). Modern low-viscosity oils are not suitable.
Emissions: Pre-Euro certification applies to pre-1992 models; Euro 1 applies to 1992–1996 models (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under ECE R85 standards. Power output is consistent across model years (Renault TIS Doc. F8M-001).

The Renault F8M 700 was used across Renault's Super 5 and Express platforms with transverse mounting. This engine received minor platform-specific adaptations-different engine mounts for the van-and no major facelift revisions that affect core mechanical compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat boss on the front left side of the cylinder block, below the injection pump (Renault TIS F8M-001). The 8th digit of the VIN is 'F' for diesel engines in this family. The F8M 700 can be visually identified by its cast-iron block, aluminum rocker cover, and the prominent Bosch mechanical injection pump on the right side. It is distinct from later F8Q engines by its 8-valve head and lack of turbocharger. For service parts, the engine serial number prefix must be verified.
The F8M 700's primary documented reliability concern is cylinder head gasket failure, with elevated incidence in vehicles subjected to frequent thermal cycling or neglected coolant maintenance. Renault internal data indicates this issue was prevalent in early production batches, while owner reports frequently cite related overheating. Adherence to correct coolant specification and change intervals is the most critical mitigating factor.
