Hello you have what is called a serpentine belt in total you have 6 pulleys that the belt goes around. On your system the fourth one down from the top is the tensioner. You will have to use a suitably sized spanner to turn the tensioner then hold into posistion until the new belt is fitted then release the spanner. Before you remove the belt make a note of how the belt routes otherwise you may get stuck.
