BRAND NEW *OEM Quality* engine coolant temperature sensor to suit Renault Megane, Koleos, Clio RS and Fluence.

If your Renault is idling roughly when cold, running the radiator fans constantly, or has logged a P0116-P0118 code, this sensor is the direct replacement to fit. Packed and shipped from Cranbourne VIC.

TO SUIT

Covers the Renault Megane B95, D95, K95, E95 and BFB in 2.0 M4R and 1.6 TCe M5M, the Koleos H45 2.5 2TR, the Clio X98 1.6 RS M5M and the Fluence X38 2.0 M4R. The Koleos and Megane share this sensor with Nissan through the Renault-Nissan alliance, which is why the Nissan 22630-44B20 number cross-references directly.

FITMENT CHECK

Renault used more than one coolant sensor across this era. Confirm your engine code and compare the 2-pin connector against the images before ordering.

ABOUT THIS SENSOR

The engine coolant temperature sensor is a thermistor that changes resistance as coolant temperature rises. The ECU reads that signal to set fuel injection, ignition timing, radiator fan operation and CVT strategy on the automatic Megane and Koleos.

When it fails the ECU defaults to a fixed temperature value, holding the engine in cold-start enrichment. On the CVT Megane this can also make the transmission hold revs or shift oddly until the fault is cleared.

COMMON SYMPTOMS OF FAILURE

Rough or high idle until the engine warms
Poor fuel economy that does not settle when warm
Temperature gauge reading incorrectly or not moving
Radiator fans running constantly or not at all
CVT holding revs or shifting unusually

How do I test a coolant temperature sensor?

The most common test is to measure the sensor resistance with a multimeter at a known coolant temperature and compare against the manufacturer resistance curve. A cold engine (20 degrees C) typically reads 2,000 to 3,000 ohms and drops to around 200 to 300 ohms at operating temperature (90 degrees C). An OBD2 scanner showing a fixed temperature reading that does not change as the engine warms up is also a strong indicator of sensor failure.

Can a faulty coolant temperature sensor cause my engine to overheat?

Indirectly yes. If the sensor reports a lower temperature than actual, the ECU may not activate the cooling fan at the correct time, allowing the engine to overheat. It can also suppress the dashboard warning light, meaning you may not be alerted until the engine is already at a dangerously high temperature. Replace a suspected faulty sensor promptly.

Do I need to drain the coolant to replace the sensor?

Not always - many coolant temperature sensors can be replaced quickly with minimal coolant loss if you work fast and have a replacement ready to thread in immediately. However on some vehicles the sensor location requires partial coolant drainage. Check the sensor position on your specific engine before starting. Always use fresh coolant when topping up after replacement.

What are the symptoms of a faulty coolant temperature sensor?

Symptoms include poor fuel economy, black smoke, engine overheating warning, incorrect temperature gauge reading, hard starting when cold, and rough idle. Fault codes P0115 to P0119 are commonly associated with coolant temperature sensor faults.

Is it safe to drive with a bad coolant temperature sensor?

A faulty coolant temperature sensor can cause the ECU to run rich fuel mixtures and prevent the cooling fan from operating correctly, risking engine overheating. Replace it promptly - it is a low-cost part that can prevent expensive engine damage.

How do I know if my coolant temperature sensor or my thermostat is faulty?

A faulty thermostat typically causes the engine to overheat or never reach operating temperature. A faulty coolant temp sensor causes incorrect gauge readings and running issues but the coolant itself may be at the correct temperature. An OBD2 scanner showing live coolant temp data helps distinguish between the two.

Are there two coolant temperature sensors on my vehicle?

Many vehicles have two sensors - one for the ECU (engine management) and one for the dashboard temperature gauge. They look similar but are not interchangeable. Check your vehicle's service manual or contact us with your vehicle details to confirm which sensor you need.
