How to Replace the Accessory Belt on the Renault Megane MK III

Model: Renault Megane Megane III, Megane 3 - Years 2008-2015
Part: V-belt

This video shows how to easily change the auxiliary belt on a Renault Megane III: open the bonnet and disconnect the negative terminal of the battery for safety. You will need to raise the front of the vehicle and remove the wheel from the passenger side, then place the car on axle stands for added safety. Next, remove the front wheel arch liner by unscrewing the screws that attach it to the bodywork, and from here you can see the auxiliary belt, which drives the alternator that charges the battery, also powers the air conditioning compressor and the water pump. Lift the tensioner pulley and remove the belt: both components should be replaced at this time. You can find the kit on auto-doc.it with code 4014870548568 for £29.77 + £9.95 shipping. Then, remove the pulley and replace it with the new one, and fit the new belt, ensuring the correct direction of rotation and proper positioning (the video will be very helpful), and then tension it properly with the tensioner pulley. Refit the wheel arch liner, the wheel, and lower the car back to the ground. Reconnect the negative terminal of the vehicle. Job done.
