The Renault C2J 717 is a 1,397 cc, inline‑four petrol engine produced between 1980 and 1985. It features a single overhead camshaft (SOHC) and two valves per cylinder, delivering modest power outputs suitable for compact economy cars. Its simple, robust design prioritized ease of maintenance and fuel economy, with outputs around 75 PS depending on the specific carburettor setup.
Fitted primarily to the Renault 5 (Supercinq) and Renault 9/11 models, the C2J 717 was engineered for affordability, reliability, and low running costs in the early 1980s. Emissions compliance for its era was managed through basic engine management and exhaust systems, meeting the applicable national standards without complex after-treatment technologies.
One documented service consideration is wear in the timing chain tensioner and guides, which can lead to chain slack and noise. This issue, referenced in Renault Technical Bulletin TB-82-04, is often linked to extended oil change intervals. In 1985, Renault phased out the C2J in favor of the updated C1E series with a timing belt drive.
Production years 1980–1985 predate standardized Euro emissions regulations; compliance was based on national standards of the time (French DRIRE Type Approval).
The Renault C2J 717 is a 1,397 cc inline‑four petrol engine engineered for supermini and compact sedan applications (1980-1985). It combines a simple SOHC valvetrain with carburettor fuel delivery to deliver reliable, economical performance. Designed for pre-Euro regulatory environments, it prioritizes serviceability and low-cost ownership.

The SOHC design offers predictable, low-stress performance ideal for city commuting but requires monitoring for timing chain rattle, a known issue documented in Renault TB-82-04. Mineral 15W-40 oil is recommended for its compatibility with the engine's older sealing materials and to ensure adequate lubrication of the timing chain tensioner. The carburettor demands periodic cleaning and adjustment to maintain optimal fuel mixture. The water pump is mechanically driven and should be inspected for leaks during routine service.
Oil Specs: Requires mineral 15W-40 specification (Renault Service Manual 1397cc). Synthetic oils not recommended for early seals.
Emissions: Pre-dates Euro standards; certified under French national regulations (DRIRE Type Approval).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across documented variants (Renault PT-1985).

The Renault C2J 717 was used across Renault's R5 and R9/R11 platforms with transverse mounting. This engine received minor carburettor updates throughout its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, near the gearbox flange (Renault TIS C2J-ID). The code will read "C2J 717" followed by a serial number. Visual identification: The engine features a single carburettor (typically Solex 32 DIS) mounted centrally on the intake manifold. It uses a timing chain (visible under a metal cover at the front of the engine) rather than a belt. Critical differentiation from the later C1E: The C2J has a timing chain, while the C1E uses a timing belt. The distributor is mounted at the rear of the cylinder head.
The C2J 717's primary reliability risk is timing chain wear and tensioner failure, with elevated incidence in high-mileage or poorly maintained examples. Renault service data indicates that neglecting oil changes significantly accelerates chain guide wear. The carburettor's mechanical nature also makes it susceptible to gumming and wear, leading to drivability issues if not maintained. While generally robust, vigilance on the timing chain is advised.
Analysis derived from Renault technical bulletins (1980-1985) and French MOT (Contrôle Technique) failure statistics (1985-1995). Repair procedures should follow manufacturer guidelines.
