The Renault E7J 720 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2001. It features a single overhead camshaft (SOHC) with two valves per cylinder and multi‑point fuel injection. This naturally aspirated unit delivers 55 kW (75 PS) and 114 Nm of torque, balancing urban drivability with modest highway capability.
Fitted primarily to the Clio II and Kangoo compact models, the E7J 720 was engineered for cost — effective, reliable transportation. Its sim…
Production years 1996–2001 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault E7J 720 is a 1,390 cc inline‑four petrol engine engineered for compact vehicles (1996-2001). It combines a simple SOHC 8-valve design with multi-point fuel injection to deliver adequate performance and good fuel economy. Designed to meet Euro 2 standards, it balances everyday usability with low running costs.

The Renault E7J 720 was used across Renault's B-segment platforms with transverse mounting. This engine received minor ECU mapping differences for the Clio versus the Kangoo, but no major revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The E7J 720's primary reliability risk is timing belt failure due to neglected replacement intervals. Renault service data indicates a high correlation between missed belt changes and engine seizures. Secondary to this, exhaust manifold stud failure is a prevalent issue documented in service bulletins, particularly affecting vehicles in high-humidity environments.

The most common questions about engine codes, what they mean, how to find them and how this database works
The E7J 720 is a mechanically simple and generally robust engine. Its long-term reliability hinges on adhering to the 60,000 km timing belt replacement schedule. With proper maintenance, including addressing the known exhaust manifold stud issue, these engines can reliably reach 200,000 km or more.
The most critical issue is timing belt failure, which destroys the engine. Other prevalent problems include snapping exhaust manifold studs causing leaks, oil leaks from the rocker cover gasket, and failing ignition coils leading to misfires. These are well-documented in Renault service information.
The E7J 720 was primarily used in the second-generation Renault Clio (1998-2001) as the 1.4L petrol option. It was also fitted to the first-generation Renault Kangoo (1997-2001). It was not used in vehicles from other manufacturers.
Significant power gains are limited by the engine's 8-valve SOHC design. Minor improvements can be achieved with a performance air filter or free-flow exhaust, yielding perhaps 3-5 kW. ECU remapping is not typically available or effective for this engine. It's best suited to its original, economical role.
Good for its size and era. In a Renault Clio II, expect real-world figures of approximately 7.0 L/100km (city) and 5.2 L/100km (highway), translating to roughly 40 mpg UK combined. Its efficiency makes it suitable for mixed urban and highway driving.
Yes. The E7J 720 is an interference engine. If the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal damage. This makes the 60,000 km timing belt replacement interval absolutely critical.
Renault specifies RN0700 10W-40 mineral or semi-synthetic oil. Using the correct specification is vital for the hydraulic lifters. The oil should be changed every 10,000 km or 12 months. Using a thinner or incorrect oil can lead to lifter noise and accelerated wear.
