BRAND NEW *OEM Quality* engine coolant temperature sensor for Mercedes-AMG C63, E63, S63, SL63 and CLK63 models with the M156 or M157 6.2L V8.

AMG V8 engines run higher combustion and under-bonnet temperatures than the standard model range, and a failing coolant sensor can trigger a limp-home mode or inaccurate temperature readout. This direct-fit replacement restores accurate ECU readings and is dispatched same-day from Cranbourne VIC.

TO SUIT

This sensor fits the M156 and M157 6.2L V8 as fitted to C63 AMG, E63 AMG, CL63/S63 AMG, ML63 AMG, SL63 AMG and CLK63 AMG, plus the AMG GT and SLS AMG, built between 2006 and 2023. See the full model, chassis and engine code list in the Compatibility section below.

FITMENT CHECK

AMG models share this sensor across several chassis codes and body styles - confirm your chassis code and engine code (M156 or M157) against the compatibility list below before ordering.

ABOUT THIS SENSOR

On the M156 and M157 6.2L V8, the coolant temperature sensor also informs the AMG-specific engine protection strategy - a false high reading can pull timing and cost real power, while a false low reading delays cooling fan activation under hard driving.

A corroded or failing sensor typically causes an inaccurate temperature gauge, reduced performance under load and a cooling fan that runs constantly or not at all - independently verified against TecDoc fitment data for this engine range.

COMMON SYMPTOMS OF FAILURE

Temperature gauge reads incorrectly or stays on cold
Check engine light with fault code P0116, P0117 or P0118
Noticeable power loss or reduced performance under load
Cooling fan running constantly or not at all
Engine running rich at idle

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.
