The Renault E7J 742 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 a modest 55 kW (75 PS) and 114 Nm of torque. Its simple, non‑interference design prioritised ease of maintenance and cost‑effective production for entry‑level models.
Fitted primarily to the Clio II (B/C57) and Kangoo (KC), the E7J 742 was engineered for urban efficiency and basic transport…
Production years 1996–2001 meet Euro 2 standards .
The Renault E7J 742 is a 1,390 cc inline‑four naturally aspirated petrol engine engineered for compact city cars (1996-2001). It combines a cast‑iron block with an aluminium head and SOHC valvetrain to deliver adequate low‑end torque for urban driving. Designed to meet Euro 2 emissions standards, it prioritises simplicity and serviceability over high performance.

The Renault E7J 742 was used across Renault's B/C57 platform with transverse mounting. This engine received minor ECU updates during its production run but no major platform-specific mechanical adaptations. All applications share identical core components. 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 742's primary documented issue is coolant leakage from the plastic intake manifold, affecting a notable number of units as they age. Renault service data indicates this is the most frequent cause for coolant loss in these engines, while its simple design otherwise contributes to good overall longevity. Neglecting coolant system maintenance can accelerate manifold failure.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the E7J 742 is generally considered a reliable and robust engine for its era. Its simple SOHC, 8-valve design and non-interference timing chain contribute to good longevity. The main age-related issue is the plastic intake manifold, which is a known and fixable problem. With regular maintenance, these engines can easily exceed 200,000 km.
The most frequent issue is coolant leakage from the plastic intake manifold. Other common problems include failing ignition coil packs, leaking thermostat housing gaskets, and worn distributor caps/rotor arms. These are all well-documented in Renault service information and are relatively inexpensive to fix.
The E7J 742 was primarily used in the second-generation Renault Clio (B/C57 platform, 1998-2001) in 1.4-litre variants (RT, RN). It was also fitted to the first-generation Renault Kangoo (KC platform, 1997-2001) as the base 1.4-litre petrol engine.
Significant power gains are difficult due to its restrictive 8-valve head and modest compression. Basic modifications like a free-flowing exhaust or performance air filter might yield minor improvements (2-5 kW). ECU remapping offers very limited potential. It's best suited as a reliable, economical engine.
Fuel economy is respectable for its time. In a Clio II 1.4, expect around 7.5-8.5 L/100km (33-38 mpg UK) in combined driving. Highway cruising can see figures closer to 6.0 L/100km (47 mpg UK). Actual consumption depends heavily on driving style and vehicle condition.
No. The E7J 742 features a non-interference design. This means that if the timing chain were to break or jump, the pistons will not collide with the valves. This is a significant safety feature that prevents catastrophic engine damage from a timing failure.
Renault recommends a 10W-40 mineral or semi-synthetic oil meeting the RN0700 specification or ACEA A3/B3 standard. Full synthetic is not necessary. Regular oil and filter changes every 10,000 km or 12 months are crucial for long-term reliability.
