The Renault E7J 728 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2001. It features a single overhead camshaft (SOHC) with 8 valves and multi‑point fuel injection, delivering 55 kW (75 PS) and 105 Nm of torque. Its simple, robust design prioritized ease of maintenance and cost‑effective ownership for entry‑level vehicles.
Fitted primarily to the Clio II (B/C57) and Kangoo I (KC) platforms, including the 1.4 RN/RT variants, the E7J 728 was engineered f…

The Renault E7J 728 is a 1,390 cc inline‑four petrol engine engineered for compact hatchbacks and vans (1996-2001). It combines a simple SOHC 8-valve architecture with multi-point fuel injection to deliver dependable, economical performance. Designed to meet Euro 2 standards, it prioritizes serviceability and low running costs.

The Renault E7J 728 was used across Renault's B/C57 and KC platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds for the Clio and Kangoo-but no major facelift revisions occurred during 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.
The E7J 728's primary reliability risk is exhaust manifold stud failure, with elevated incidence in vehicles subjected to frequent short trips. Renault workshop data indicates this is the most common repair for engines beyond 100,000 km, while general mechanical failures are rare. Thermal cycling makes upgrading to stainless steel studs a recommended preventative measure.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the E7J 728 is renowned for its mechanical simplicity and durability. With regular oil changes and basic maintenance, it can easily exceed 200,000 km. The main long-term issue is the exhaust manifold studs, which are inexpensive and straightforward to replace.
The most frequent issue is broken exhaust manifold studs. Other common problems include a dirty idle control valve, failing coolant temperature sensor, and worn distributor cap/rotor. These are all relatively simple and inexpensive fixes.
The E7J 728 was primarily used in the second-generation Renault Clio (B/C57, 1998-2001) in 1.4 RN/RT trims and the first-generation Renault Kangoo (KC, 1997-2001) in the base 1.4 model. It was not used in other manufacturers' vehicles.
Significant power gains are difficult due to its SOHC 8-valve design. Basic modifications like a performance air filter and free-flow exhaust might yield 3-5 kW. More aggressive tuning is not cost-effective and can strain the aging engine components.
Fuel economy is respectable for its era. Expect around 7.5 L/100km (38 mpg UK) in combined driving for a Clio, and slightly more for a Kangoo van. Real-world figures depend heavily on driving style and vehicle condition.
No. The E7J 728 is a non-interference engine. If the timing chain were to fail completely, the pistons and valves will not collide, preventing catastrophic internal engine damage. This is a key point of its robust design.
Renault specifies RN0700 10W-40 mineral or semi-synthetic oil. A good quality ACEA A3/B3 10W-40 oil is also suitable. Regular changes every 10,000-15,000 km are more important than using expensive full-synthetic oil for this engine.
