Renault K4M-848 Engine (2015–2021) – Specs, Problems & Compatibility Database

The Renault K4M 848 is a 1,598 cc, inline‑four petrol engine produced between 2015 and 2021. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering outputs typically around 80 kW (109 PS) and 148 Nm of torque. Its simple, non‑turbocharged architecture prioritises reliability and cost‑effective ownership.

Fitted to models such as the Captur II, Clio V, and Mégane IV facelift, the K4M 848 was engineered for dependable

Compliance Note:

Production years 2015–2018 meet Euro 6b standards; 2019–2021 models may have Euro 6d-TEMP compliance depending on market (VCA UK Type Approval #VCA/EMS/5680).

Renault K4M-848 Technical Specifications

The Renault K4M 848 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact and family hatchbacks (2015-2021). It combines multi‑point fuel injection with a DOHC 16‑valve head to deliver smooth, linear power and predictable drivability. Designed to meet Euro 6 (and some market‑specific Euro 6d-TEMP) standards, it balances everyday performance with economy.

Renault K4M-848 Compatible Models

The Renault K4M 848 was used across Renault's B/C platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Captur II and revised exhaust manifolds in facelifted Mégane IV models-and from 2021 the Clio adopted hybrid powertrains, creating interchange limits. All adaptations are documented in OEM technical bulletins.

Common Reliability Issues - RENAULT K4M-848 Compatible Models

The K4M 848's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in vehicles subjected to frequent short trips. Renault internal data indicated a notable number of cases before 80,000 km, while owner reports frequently cite timing belt failure as a major concern if neglected. Infrequent oil changes and use of incorrect oil viscosity make adherence to the RN0700 specification critical.

Exhaust camshaft lobe wear
Symptoms: Rough idle, misfire under load, metallic tapping from the cylinder head, reduced power output.
Cause: Insufficient lubrication or use of non-specification oil leading to accelerated wear on the exhaust camshaft lobes.
Fix: Replace the exhaust camshaft with the latest revised part per service bulletin; inspect and replace lifters if necessary; ensure correct oil specification is used.
Timing belt failure
Symptoms: Engine will not start, sudden loss of power, loud clattering noise if belt breaks while running.
Cause: Failure to replace the timing belt and tensioner at the recommended interval (120,000 km or 5 years), leading to belt snapping or jumping teeth.
Fix: Replace the entire timing belt kit (belt, tensioner, idler pulleys) with OEM parts at the specified interval; inspect water pump for signs of failure during replacement.
Coolant leaks from plastic housing
Symptoms: Visible coolant puddles under the car, sweet smell, low coolant level warning, engine overheating.
Cause: Age-related brittleness and cracking of the plastic coolant thermostat housing and associated pipes.
Fix: Replace the leaking plastic housing or pipe with a new OEM unit; avoid overtightening clamps during reassembly.
Ignition coil pack failure
Symptoms: Engine misfire, rough running, loss of power, illuminated check engine light (often with P030X codes).
Cause: Heat cycling and electrical degradation causing the internal components of the coil pack to fail.
Fix: Replace the faulty ignition coil pack(s) with new OEM units; inspect spark plugs for wear and replace if necessary.

RENAULT K4M-848 FAQ Common Questions Answered

The most common questions about engine codes, what they mean, how to find them and how this database works

The K4M 848 is generally robust with a simple design, but long-term reliability hinges on strict maintenance. The critical items are timely timing belt changes (every 120,000 km/5 years) and using the correct RN0700 (5W-40) oil to prevent camshaft wear. With proper care, these engines can easily exceed 200,000 km.

The most frequent issues are exhaust camshaft lobe wear (causing rough running), timing belt failure if neglected, coolant leaks from plastic housings, and ignition coil pack failures. These are well-documented in Renault service bulletins and owner reports.

This 1.6L petrol engine was primarily used in the Renault Captur II (2019-2021), Clio V (2019-2021), and Mégane IV facelift (2018-2021), typically badged as '1.6 16V'. It was not used in Dacia or Nissan models of that era.

Yes, but gains are modest. ECU remaps can yield around +5-10 kW by optimizing fuel and ignition timing. Significant power increases require forced induction (turbo/supercharger), which is complex and costly. Most tuning focuses on improving throttle response rather than peak power.

Real-world fuel economy is respectable. Expect around 6.5-7.5 L/100km (38-43 mpg UK) in mixed driving for a Captur or Clio. The slightly heavier Mégane may achieve 7.0-8.0 L/100km (35-40 mpg UK). Consumption is higher in city traffic and with aggressive driving.

Yes. The K4M 848 is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing severe internal damage that requires a costly engine rebuild or replacement.

Renault mandates RN0700 specification oil, typically SAE 5W-40. Using this specific oil is crucial for protecting the camshafts from premature wear. Always use a high-quality, fully synthetic oil that meets this standard and change it every 15,000 km or 12 months.
