The Renault F3P 704 is a 1,721 cc, inline‑four petrol engine produced between 1989 and 1996. It features a cast‑iron block, aluminium head, and a single overhead camshaft (SOHC) with two valves per cylinder. In standard European specification, it produced 66 kW (90 PS) and 135 Nm of torque, offering adequate performance for its era's compact family cars.
Fitted primarily to the Renault 19 (Phase 1) and early Clio models, the F3P 704 was engineered for cost‑effective, relia…
Production years 1989–1996 meet Euro 1 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault F3P 704 is a 1,721 cc inline‑four petrol engine engineered for compact hatchbacks and saloons (1989-1996). It combines a robust cast‑iron block with a simple SOHC valvetrain to deliver dependable, economical performance. Designed to meet Euro 1 standards, it prioritizes serviceability and low running costs over high output.

The Renault F3P 704 was used across Renault's R19 platform with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds for carburetted vs. injected versions-and no significant facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The F3P 704's primary reliability risk is exhaust manifold stud failure, with elevated incidence in high-mileage or frequently short-trip vehicles. Renault internal service data indicated this was a common workshop repair, while the simple mechanical design otherwise proved very durable. Thermal stress from repeated heating and cooling cycles makes using updated replacement hardware critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the F3P 704 is renowned for its mechanical simplicity and durability. With regular maintenance, particularly valve adjustments and oil changes, these engines can easily surpass 300,000 km. The main known weakness, the exhaust manifold studs, is easily rectified with updated parts.
The most frequent issues are broken exhaust manifold studs, carburettor or single-point injection tuning problems, and the need for periodic valve clearance adjustments. Oil leaks from the rocker cover gasket are also common on high-mileage engines.
The F3P 704 was primarily used in the first-generation Renault 19 (all trim levels from 1989-1996) and the early first-generation Renault Clio (RN and RT trims from 1991-1996). It was the base 1.7L petrol engine for these models.
Minor gains are possible. Options include fitting a performance exhaust, re-jetting the carburettor, or remapping the injection ECU. Significant power increases are limited by the 8-valve head design. Most tuning focuses on improving drivability rather than peak power.
Real-world fuel economy is around 8.5 L/100km (33 mpg UK) in mixed driving for a Renault 19. Highway cruising can yield 6.5 L/100km (43 mpg UK), while city driving may consume 10.5 L/100km (27 mpg UK). Results vary significantly with driving style and vehicle condition.
No. The F3P 704 is a non-interference engine. If the timing chain were to fail, the pistons and valves will not collide, preventing catastrophic internal damage. This is a key factor in its reputation for reliability.
Renault specified a mineral-based 10W-40 or 15W-40 engine oil for the F3P 704. While modern synthetic oils can be used, a quality mineral or semi-synthetic oil changed every 10,000 km is perfectly adequate and cost-effective for this engine design.
