Getting the proper tools is actually key, and to finish the job you should only require a basic set involving sockets and grips, ratchets and related auto repair equipment. If you’re fortunate enough to have a spacious engine compartment with space to help swap out the fan belt and never have to dig deep, then you’re good to go.
Removing the serpentine belt is your first step, with your replacement belt in the ready. If you can’t remember the last time (if ever) the belt was replaced, then this is a pretty good the perfect time to consider it. Nonetheless, if the serpentine belt on your own engine is reasonably new, just take it off from the Belt Tensioner and leave it to remain in it’s location.
The belt is under tension, so you have got to release the tension before you’re capable of remove the belt. Find the area on the belt tensioner you can attach a wrench or tool to. Normally a clockwise motion, when you rotate the tensioner up against the spring tension, this releases it and also the belt is able to be removed off of the belt tensioner.
From this point, positioniong a Belt Tensioner is usually a pretty simple undertaking. Two or more bolts will attach the tensioner to the engine block, so you can unfasten these using a wrench. The tensioner will drop off after you remove the last bolt, so be prepared to stabilize it as it can be heavy and might damage other areas of your vehicle if it fell.
Secure the fresh Belt Tensioner in the same way the old one was removed: hold it set up and bolt it in your engine block. Slip the belt back on in an identical way to how it was removed by tightening up the tensioner spring and sliding your belt back on.
