How to replace the alternator belt in the Smart ForTwo 451 CDI

Model: Smart Smart 451 - Years 2007-2015
Part: V-belt

In this guide we will explain the steps to take to replace the alternator belt in the Smart ForTwo 451 CDI. Let's start by lifting the car, disassemble the right rear wheel and using a flat screwdriver or a lever, slide out the 2 pins of the belt cover and remove it. Let's now move on to the removal of the elastic belt: we position the tool for extraction and rotate the crankshaft with a Torx E18. Once the belt has been extracted, loosen the alternator fixing bolts with a 15mm bush and move it to be able to remove the alternator belt. Before completely removing the alternator belt, let's memorize its path, so that it can be put back in the right position. We insert the new belt and reposition the alternator; using the appropriate tool, mount the previously removed elastic belt. We reassemble the casing and finally the wheel.
