The Renault K7J 701 is a 1,390 cc, inline‑four petrol engine produced between 1996 and 2001. It features a single overhead camshaft (SOHC) design with 8 valves and multi‑point fuel injection. This naturally aspirated unit delivered 55 kW (75 PS) and 114 Nm of torque, offering predictable, linear power delivery for urban and highway driving.
Fitted primarily to the Clio II and Twingo platforms, the K7J 701 was engineered for dependable, cost — effective performance in comp…
Production years 1996–2001 meet Euro 2 standards .
The Renault K7J 701 is a 1,390 cc inline‑four naturally aspirated petrol engine engineered for compact city vehicles (1996-2001). It combines multi‑point fuel injection with a SOHC 8‑valve head to deliver simple, robust performance. Designed to meet Euro 2 standards, it prioritizes reliability and low-cost ownership.

The Renault K7J 701 was used across Renault's Clio II and Twingo platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU calibrations for different body weights-and no significant facelift revisions affecting core compatibility 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the K7J 701 is renowned for its simplicity and robustness. Its main known issue is the ignition distributor, which is a simple and inexpensive fix. The absolute key to long-term reliability is adhering strictly to the 60,000 km timing belt replacement schedule to avoid catastrophic engine damage. With basic maintenance, these engines can easily surpass 300,000 km.
The most common issues are ignition distributor failure (cap and rotor) and the critical need for timely timing belt replacement. Other frequent problems include coolant temperature sensor failure and carbon buildup in the throttle body. These are all well-documented in Renault service manuals and are inexpensive to repair.
The K7J 701 was primarily used in the first phase of the Renault Clio II (1998-2001) and the first-generation Twingo (1996-2000), both badged as the '1.4 8V'. It was a common engine for Renault's entry-level city cars during this period.
Significant power gains are difficult due to the engine's simple SOHC 8-valve design. Minor improvements can be had from an ECU remap or installing a less restrictive exhaust, but gains are typically modest (5-10 kW). Most owners value its reliability and fuel economy over tuning potential.
Fuel economy is excellent for its era. Expect around 7.5-8.5 L/100km (33-38 mpg UK) in mixed urban driving and 5.5-6.5 L/100km (43-51 mpg UK) on the highway in a Clio II. Its lightweight design and modest power output make it very economical.
Yes. The K7J 701 is an interference engine. If the timing belt were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. This makes adhering to the 60,000 km replacement interval absolutely critical.
Renault recommends oil meeting the RN0700 specification, typically a 10W-40 mineral or semi-synthetic. While not as critical as in newer engines, using the correct specification ensures optimal lubrication and engine longevity. Change intervals should not exceed 15,000 km or 12 months.
