Its got an automatic tensioner, so at a guess its a new belt and tensioner thats needed.

lol your not wrong sean

right the symptons you say basically mean you will need a new belt and tensioner

first thing
draw a picture of the belt location so when you come to refit it you get it right

to remove belt

15mm socket on a long ratchet , put the socket on the nut on the tensioner , turn this anti clockwise and this will remove the tension from the belt

remove belt from tensioner and rollers etc

to remove tensioner

the tensioner is held on with 2 x 6mm allen bolts , undo these and the tensioner will come away easy

refit new tensioner and tighten 6mm allen bolts up really tight

when refitting the new belt its prob easier to have 2 people ,
one to hold belt over the rollers and other to do the tensioner part


rethread new belt over all pulleys and guide rollers except the tensioner making sure that the grooves on the belt line up with the grooves on the pulleys that have them

with 2nd person holding belt in place , use the 15mm socket again and turn tensioner anti clock wise with one hand and when low enough push the belt up onto the tensioner roller

release tension so belt goes tight

check belt it located properly

start vehicle , smile , scratch nuts and stand back and admire handy work
