In this guide, we will see the instructions that will allow you to replace the coolant in the Sym GTS 300i scooter. First, place your scooter on the centre stand and start removing the plastic panel to access the cap of the coolant reservoir; then disconnect the coolant hose, allowing it to drain into a container for about ten minutes, as shown in the video. At this point, pour the new radiator fluid until it reaches the maximum level mark on the reservoir!
