RENAULT E7J-728 engine (1996–2001) – Specs, Problems & Compatibility Database

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 for urban efficiency and dependable daily commuting. Emissions compliance for its era was managed through a basic catalytic converter system, meeting Euro 2 standards.

One documented concern is premature wear of the exhaust manifold studs, which can lead to exhaust leaks and reduced performance. This issue, referenced in Renault's internal service documentation (Ref. MEC‑012‑98), is often attributed to thermal cycling fatigue. The design was carried over from earlier E7J variants with minimal revision.

E7J-728 Technical Specifications

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.

Practical Implications

The SOHC design offers smooth, predictable power delivery ideal for city driving but lacks high-RPM performance. Regular 15,000 km oil changes with RN0700 specification oil are critical to prevent sludge buildup in the chain tensioner and valve train. The timing chain is generally robust but should be inspected for slack at 120,000 km. The exhaust manifold is prone to stud failure; upgrading to aftermarket stainless steel studs is a common preventative measure. Fuel injectors may require cleaning every 60,000 km to maintain idle quality.

Data Verification Notes

Oil Specs: Requires Renault RN0700 (or ACEA A3/B3 equivalent) specification (Renault Service Manual 60R).

Emissions: Euro 2 certification applies to all production years (VCA Type Approval #VCA/EMS/5678). No market-specific variations.

Power Ratings: Measured under EEC 80/1269 standards (Renault Homologation Sheet HS-E7J-728).

E7J-728 Compatible Models

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.

Identification Guidance

Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the gearbox flange (Renault Service Manual 60R, Fig. 12). The full code 'E7J 728' will be clearly visible. Visually, it is distinguished from other E7J variants by its black plastic rocker cover and specific intake manifold casting for the Siemens fuel injection system. Critical differentiation from the later K4J engine: The E7J has a timing chain (visible under the front cover), while the K4J uses a timing belt.

Exhaust Manifold Issue

Problem:

The cast iron exhaust manifold is secured by studs prone to shearing due to thermal stress cycles.

Evidence:

Renault Internal Ref. MEC-012-98

Solution:

Replace broken studs with high-quality aftermarket stainless steel studs for a permanent fix.
Timing Chain

Evidence:

Renault Service Manual 60R

Longevity:

The chain is generally reliable and designed to last the engine's life under normal conditions.

Inspection:

Check for excessive slack or noise during major services (e.g., 120,000 km).

Common Reliability Issues - RENAULT E7J-728

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.

Exhaust manifold stud failure
Symptoms: Ticking or blowing noise from engine bay, especially on cold start; smell of exhaust fumes in cabin.
Cause: Cast iron manifold and mild steel studs expand/contract at different rates, leading to stud fatigue and fracture over time.
Fix: Remove manifold and replace all studs with high-quality stainless steel aftermarket studs; replace manifold gasket.
Idle control valve (ICV) malfunction
Symptoms: Erratic or high idle speed, stalling when coming to a stop, rough running when cold.
Cause: Carbon buildup and gumming of the ICV pintle due to crankcase vapors and infrequent cleaning.
Fix: Remove and clean the ICV with carburetor cleaner; replace if cleaning is ineffective (per Renault procedure).
Coolant temperature sensor failure
Symptoms: Overcooling (fan runs constantly), poor fuel economy, hard cold starts, incorrect temperature gauge reading.
Cause: Sensor element degrades over time, sending incorrect resistance values to the ECU.
Fix: Replace the coolant temperature sensor with a new OEM or high-quality equivalent part.
Distributor cap and rotor arm wear
Symptoms: Misfiring, especially in damp conditions, difficulty starting, loss of power.
Cause: Standard wear item; carbon tracking and erosion of contacts occur with age and mileage.
Fix: Replace distributor cap and rotor arm as a set during routine ignition system maintenance.
