Renault K4M-801 Engine (2012–2018) – Specs, Problems & Compatibility Database

The Renault K4M 801 is a 1,598 cc, inline‑four petrol engine produced between 2012 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering outputs around 78 kW (106 PS) and 145 Nm of torque. Its variable valve timing system optimises the trade‑off between low‑end responsiveness and fuel economy for everyday urban and highway driving.

Fitted to models like the Clio IV, Captur, and Twingo III, the K4M 801 was engi

Renault K4M-801 Compatible Models

The Renault K4M 801 was used across Renault's B platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Captur and revised intake manifolds in the Clio IV-and from 2016 the adoption of emissions hardware for Euro 6 compliance, creating minor service part differences. All adaptations are documented in OEM technical bulletins.

Common Reliability Issues - RENAULT K4M-801 Compatible Models

The K4M 801's primary documented concern is exhaust camshaft lobe wear, with elevated incidence in high-mileage or frequently high-load vehicles. Renault internal reports noted this issue predominantly in pre-2016 builds, while owner feedback often cites ignition coil failures as a common electrical fault. Sustained high RPM use and infrequent oil changes accelerate cam wear, making adherence to service intervals critical.

Exhaust camshaft lobe wear
Symptoms: Loss of power, misfire under load (especially above 4,000 rpm), increased oil consumption, metallic particles in oil filter.
Cause: Marginal lubrication film on exhaust cam lobes under high thermal load, exacerbated by extended oil change intervals or low-quality oil.
Fix: Replace camshaft with latest OEM-specified part per Technical Note 4125B; inspect followers and renew engine oil with correct specification.
Ignition coil failure
Symptoms: Engine misfire (often on a single cylinder), rough idle, 'Check Engine' light with misfire codes, difficulty starting.
Cause: Heat cycling and electrical stress cause internal breakdown of the coil windings or insulation over time.
Fix: Replace faulty ignition coil(s) with OEM unit; inspect spark plugs and HT leads for wear or damage during replacement.
Thermostat housing/coolant leaks
Symptoms: Coolant smell, low coolant level warning, visible coolant residue around thermostat housing or water pump area.
Cause: Ageing and thermal cycling cause plastic thermostat housings and associated O-rings/gaskets to become brittle and crack.
Fix: Replace thermostat housing assembly and associated gaskets with OEM parts; bleed cooling system thoroughly after repair.
Timing chain tensioner rattle
Symptoms: Distinctive metallic rattle from front of engine on cold start, lasting 1-2 seconds, may worsen with engine age.
Cause: Wear or loss of hydraulic pressure in the chain tensioner piston, allowing slight chain slack during initial oil pressure build-up.
Fix: Replace timing chain tensioner with latest OEM part; inspect chain and guides for wear if rattle is persistent or loud.

RENAULT K4M-801 FAQ Common Questions Answered

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

Generally yes, the K4M 801 is known for robust mechanicals. The main caveat is potential exhaust camshaft wear in pre-2016 models under high stress or poor maintenance. Using the correct 5W-40 oil and adhering to service intervals greatly mitigates this risk, making it a dependable engine for high mileage.

The most frequent issues are ignition coil failures causing misfires, coolant leaks from the plastic thermostat housing, and timing chain tensioner rattle on cold start. For early models, exhaust camshaft lobe wear is a documented mechanical concern addressed in Renault service bulletins.

This 1.6L petrol engine was widely used in Renault's compact lineup from 2012-2018. Key models include the Clio IV (2012-2018), Captur (2013-2018), Twingo III (2014-2018), and the Dacia Sandero II (2012-2018). It powered various 1.6 trim levels across these vehicles.

Minor gains are possible. The naturally aspirated K4M 801 responds modestly to ECU remaps or induction/exhaust upgrades, typically yielding 5-10 kW extra. Significant power increases require forced induction, which is complex and costly. It's best suited to its stock, economical tuning.

Real-world fuel economy is reasonable. Expect around 7.0-8.0 L/100km (35-40 mpg UK) in mixed driving for a Captur or Clio. Smaller, lighter Twingos may achieve 6.5-7.5 L/100km (38-43 mpg UK). Figures vary significantly with driving style and vehicle condition.

Yes. The K4M 801 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.

Renault specifies a 5W-40 synthetic oil meeting the RN0700 standard. Using this specific oil, or an equivalent ACEA A3/B4 5W-40, is crucial for protecting the engine, particularly the camshafts, and ensuring longevity. Change intervals should not exceed 15,000 km or 12 months.
