The Renault E7J 626 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2001. It features a single overhead camshaft (SOHC) and multi‑point fuel injection, delivering modest power outputs suitable for compact city cars. Its simple, non‑interference design prioritises ease of maintenance and cost‑effective ownership.
Fitted primarily to the Renault Clio II (B/C57) and Twingo I (C06), the E7J 626 was engineered for urban efficiency and low running costs…
Production years 1996–2001 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault E7J 626 is a 1,390 cc inline‑four petrol engine engineered for supermini applications (1996-2001). It combines a simple SOHC valvetrain with multi‑point fuel injection to deliver adequate urban performance and low running costs. Designed to meet Euro 2 standards, it prioritises mechanical simplicity and ease of service.

The Renault E7J 626 was used across Renault's Clio II and Twingo I platforms with transverse mounting. This engine received minimal platform-specific adaptations and no significant mid-cycle revisions, ensuring broad parts interchangeability. All applications are documented in OEM technical bulletins.
The E7J 626's primary reliability risk is exhaust manifold stud failure, with elevated incidence in vehicles subjected to frequent short trips. Renault internal data indicated this as a common warranty claim, while its simple design generally ensures good long-term durability with basic maintenance. Neglecting oil changes can lead to tappet noise and sludge buildup.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the E7J 626 is generally very reliable long-term due to its simple, non-interference design. The main known issue is exhaust manifold studs, which is a repairable nuisance rather than a fatal flaw. With regular oil changes and basic maintenance, these engines can easily exceed 200,000 km.
The most common issues are snapped exhaust manifold studs, noisy hydraulic tappets (often from poor oil maintenance), clogged fuel injectors causing rough idle, and failing coolant temperature sensors. These are well-documented and relatively inexpensive to fix.
The E7J 626 was used in the second-generation Renault Clio (B/C57 chassis, 1998-2001) and the first-generation Renault Twingo (C06 chassis, 1996-2000). It was typically found in the 1.4-litre variants of these models.
Significant power gains are difficult. Simple modifications like a performance air filter or exhaust may yield minor improvements. ECU remapping is not common or highly effective on this older, simpler engine. Its strength is reliability, not tunability.
Fuel economy is respectable for its era. Expect around 7.5 L/100km (38 mpg UK) in combined driving for a Clio, and slightly better for a lighter Twingo. Real-world figures range from 35-45 mpg UK depending on driving style and condition.
No. The E7J 626 is a non-interference engine. If the timing chain were to break, the pistons and valves will not collide, preventing catastrophic internal damage. The engine will simply stop running, requiring a chain replacement.
Renault recommends RN0700 specification oil, typically SAE 10W-40. ACEA A3/B3 specification oils are also suitable. Using the correct viscosity is crucial for quiet tappet operation and engine longevity. Change intervals should be 10,000 km or 12 months.
