Change of cooling temperature sensor 206 S16

Locating the bleeder screws

One on the upper hose that goes to the heater radiator

One on the 35 Torx water box

Remove the cap from the expansion tank and fill the jar to the brim.

Open both bleeder screws, close them once the liquid comes out correctly without air bubbles

The level in the jar will drop, check each time that it does not drop below the MINI

Start the vehicle

Set the heating and ventilation to the maximum position

Let the vehicle warm up, the "normal" temperature on my vehicle is 90 degrees, the fan comes on at 100 degrees

I accelerate slightly in order to increase the temperature of the coolant and thus trigger my fan.

Once the MAXIMUM temperature is reached, I repeat a hot purge, in order to evacuate the remaining air.

Don't forget to check the level of the expansion tank

Turn off the engine, then top up the level when cold.

Open the engine hood

Locate the probe

Unclip the electrical terminal by lifting the tab

I use a 16MM ring wrench to loosen the probe

When removing the probe, coolant will leak out.

By loosening the probe the coolant will flow out

I unlock the probe with the 16 mm key and finish loosening it by hand so that I can immediately replace the new one and only lose a minimum of coolant.

Place a basin under the vehicle

We can see the liquid starting to flow

Compare the two probes

Old probes

I replace the old probe with a Calorstat WS2606 brand probe

Replace the new probe and tighten it with the 16 mm wrench

Reconnect the electrical terminal

Top up the coolant, then bleed if necessary.
