The Renault E7J 724 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2001. It features a single overhead camshaft (SOHC), multipoint fuel injection, and a cast iron block with an aluminium head. In standard form, it delivered approximately 55 kW (75 PS) and 114 Nm of torque, designed for compact family cars where balanced performance and economy were key.

The Renault E7J 724 is a 1,390 cc inline‑four naturally aspirated petrol engine engineered for compact family vehicles (1996-2001). It combines a robust cast iron block with multipoint fuel injection to deliver a balance of power and fuel efficiency. Designed to meet Euro 2 emissions standards, it prioritises drivability and low running costs for daily use.

The Renault E7J 724 was used across Renault's C-segment platforms with transverse mounting. This engine received minor platform-specific adaptations-slight variations in accessory bracketry for the Scénic-but no major facelift revisions occurred, ensuring broad parts interchangeability within its production run. All adaptations 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.
Analysis derived from Renault technical bulletins (1999-2001) and aggregated European owner association repair data (2000-2010). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The E7J 724 is generally a robust and simple engine. Its main vulnerabilities are the EGR valve and the critical timing belt. Addressing EGR issues proactively and strictly adhering to the 60,000 km timing belt replacement schedule allows these engines to reliably reach 200,000 km or more.
The most frequent issues are a sticking EGR valve causing rough idle, ignition system faults (coils, leads, distributor), and the critical risk of timing belt failure if not replaced on schedule. Coolant thermostat failures are also relatively common. These are well-documented in Renault service information.
This 1.4L petrol engine was used in the first-generation Renault Mégane (hatchback, sedan, coupe) and the first-generation Renault Scénic MPV, primarily in base and mid-level trims from 1996 to 2001.
Significant power gains are limited by its SOHC 8-valve design. Basic induction and exhaust modifications can yield minor improvements in throttle response, but substantial increases require internal modifications. It's not a common choice for serious tuning due to its modest base output.
Reasonable for its era and size. In a Renault Mégane, expect combined figures around 7.0-7.5 L/100km (approx. 38-40 mpg UK). The heavier Scénic might return 7.5-8.0 L/100km (approx. 35-37 mpg UK). Economy is best achieved with steady highway driving.
Yes. The E7J 724 is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing significant internal damage requiring a major engine rebuild. This makes the 60,000 km belt change non-negotiable.
Renault specifies oil meeting the RN0700 standard, typically a 10W-40 mineral or semi-synthetic. Using a quality ACEA A3/B3 10W-40 oil is also acceptable. Regular changes every 10,000-15,000 km are vital for engine longevity.
