To replace the temperature sensor, open the bonnet and locate it in the position shown in the video. It is located low on the right side of the engine block and should be green, as shown in the video.

To extract it, first remove the clip, which is a flat piece open on one side like a fork. Then, extract the clip to free the temperature sensor.

This is not only a replacement but also a check, as I had coolant leaks upon reassembling the sensor. If you need to replace the temperature sensor, be very careful to reposition the rubber ring that acts as a sealing gasket to avoid coolant leaks.

It is a simple operation that, if done carefully, can save you the cost of a garage intervention. Car model: VW GOLF 2.0 petrol manual year 2001. Necessary tools: straight and/or curved fine-nose pliers.

How to reset the Service light on a 2019 Jeep Renegade?

The Service light, depicted as a yellow spanner, illuminates as scheduled to remind the driver that it is time for scheduled maintenance. This means that the set mileage has been reached, or the expected time has passed. The procedure involves turning on the instrument cluster, pressing the accelerator three times, and then turning off the ignition. After this, keep the brake pressed, turn the ignition back on, and then turn it off again. Upon the next ignition, you will notice that the light has been reset.
