Model: Vauxhall Astra Astra G - Years 1998-2006
Part: Thermostat

Today's instructions will allow us to dismantle and replace the thermostat of the Opel Astra 1.6. First, we open the hood of the car and start locating the thermostat, located on the top left; then we disconnect the coolant pipe, letting the fluid drain into a container, as shown in the video. At this point, we disconnect the thermostat pipe and unscrew the fixing screws at the base to remove it and replace it with the new original one; we reassemble the thermostat and top up with the new coolant fluid!
