The Renault C1E 714 is a 1,390 cc, inline‑four naturally aspirated petrol engine produced between 1996 and 2000. It features multi — point fuel injection, a single overhead camshaft (SOHC) design, and a cast — iron block with an aluminum head. In its primary application, it produced 55 kW (75 PS), prioritizing reliability and low — cost ownership for compact city cars.
Fitted exclusively to the Clio II (B/C — segment), the C1E 714 was engineered as an entry — level engine focus…
Production years 1996–2000 meet Euro 2 standards .
The Renault C1E 714 is a 1,390 cc inline‑four naturally aspirated petrol engine engineered for supermini applications (1996-2000). It combines multi-point fuel injection with a simple SOHC valvetrain to deliver predictable performance and low running costs. Designed to meet Euro 2 standards, it prioritizes mechanical simplicity and serviceability.

The Renault C1E 714 was used exclusively on Renault's Clio II platform with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production, ensuring broad parts interchangeability. All specifications 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The C1E 714 is renowned for its long-term reliability when basic maintenance is performed. Its main weakness is the timing belt tensioner, especially in early (pre-1998) models. Replacing the belt and tensioner at or before 60,000 km and using the correct RN0700 oil are the keys to ensuring this engine lasts for hundreds of thousands of kilometers.
The most frequent issues are timing belt tensioner pulley failure, catalytic converter degradation, Idle Air Control valve malfunction, and coolant temperature sensor failure. The timing belt issue is well-documented in Renault technical notes and is the most critical to address to prevent engine damage.
The C1E 714 engine was used exclusively in the second-generation Renault Clio (1996-2000), specifically in the 1.4i 75 PS variants. It was not used in any other Renault models or licensed to other manufacturers during this period.
The C1E 714 has limited tuning potential due to its simple SOHC 8-valve design. Basic modifications like a performance air filter and free-flow exhaust might yield minor gains of 3-5 kW. Significant power increases would require forced induction or a head swap, which is generally not cost-effective for this engine.
Real-world fuel economy is good for its era. Expect around 8.5 L/100km (city) and 5.5 L/100km (highway), translating to approximately 33-43 mpg (UK) combined. Actual figures depend heavily on driving style and the condition of the ignition and fuel systems.
Yes. The C1E 714 is an interference engine. If the timing belt breaks or slips, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes adhering to the 60,000 km timing belt replacement schedule absolutely critical.
Renault specifies RN0700 specification oil, typically in 10W-40 viscosity. Using the correct oil is vital for protecting the hydraulic lifters and ensuring proper lubrication of the timing belt tensioner. Never use an oil that doesn't meet these Renault specifications.
