Open the hood of your Corsa.
Locate the fan belt. It is a black, rubber belt that runs between the crankshaft and the water pump.
Loosen the tensioner pulley bolt. The tensioner pulley is a small, metal wheel with a bolt in the center. It is located near the fan belt.
Using a pry bar or a wrench, pry the tensioner pulley away from the fan belt. This will loosen the fan belt.
Slide the fan belt off of the pulleys.
Measure the old fan belt. The new fan belt should be the same length as the old fan belt.
Install the new fan belt. Slide it onto the pulleys in the same way that you removed the old fan belt.
Tighten the tensioner pulley bolt. Tighten the bolt until the fan belt is snug.
Start your Corsa and let it run for a few minutes. Check the fan belt to make sure that it is properly tensioned.
If necessary, adjust the tensioner pulley bolt to achieve the correct tension.
Remember, if you are uncomfortable with any of these steps, it is best to have your Corsa serviced by a qualified mechanic.
