The Renault C3J 710 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2000. It features a single overhead camshaft (SOHC) and multi‑point fuel injection, delivering modest power outputs suitable for city and suburban driving. Its cast‑iron block construction provides inherent durability for everyday use.
Fitted primarily to the Renault Clio II (B/C57) and Twingo I (C06), the C3J 710 was engineered for economical, reliable urban mobility. Emissions compliance for its production era was managed through its electronic fuel injection system and catalytic converter, meeting Euro 2 standards.
A documented service consideration involves the exhaust manifold gasket, prone to developing leaks over time due to thermal cycling. This is addressed in Renault's technical documentation, which recommends inspection during major services. The design was succeeded by more advanced EC engine variants.
Production years 1996–2000 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault C3J 710 is a 1,390 cc inline‑four petrol engine engineered for compact city cars (1996-2000). It combines multi‑point fuel injection with a single overhead camshaft to deliver economical, reliable urban performance. Designed to meet Euro 2 standards, it prioritizes simplicity and cost‑effective ownership.

The SOHC design offers straightforward, economical performance ideal for city driving but requires adherence to 15,000 km oil change intervals to maintain longevity. Renault RN0700/RN0710 specification oil is critical for optimal engine protection. The timing chain is generally robust but should be inspected for tension and noise during major services. The exhaust manifold gasket is a known wear item; leaks manifest as a ticking noise and should be replaced with the OEM gasket per service guidelines to ensure a proper seal.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual). Equivalent ACEA A3/B3 oils are acceptable.
Emissions: Euro 2 certification applies to all 1996–2000 production models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Renault TIS Doc. C3J-001).

The Renault C3J 710 was used across Renault's Clio II and Twingo I platforms with transverse mounting. This engine received minor ECU calibration adaptations between the Clio and Twingo applications. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS C3J-001). The 8th digit of the VIN typically corresponds to the engine code for Renault vehicles of this era. The C3J 710 is visually identified by its black plastic camshaft cover and the Magneti Marelli IAW 490 ECU. Critical differentiation from the later K4J engine: The C3J uses a distributor-based ignition system, whereas the K4J uses coil-on-plug. Service parts are generally interchangeable within the C3J family, but ECU part numbers differ between Clio and Twingo applications.
The C3J 710's primary reliability consideration is exhaust manifold gasket failure, with elevated incidence in high-mileage or frequently short-trip vehicles. Renault workshop data indicates this is a common service item after 100,000 km, while general owner feedback highlights its prevalence. Regular thermal cycling makes gasket material integrity critical.
