At the front of the engine is a single serpentine drive belt, whose function and material composition make it a vital component in the overall functioning of the engine as well as its various units. The belt should be checked from time to time, given its usage and materialistic nature. An alternator, a power steering pump, a water pump and an air conditioning compressor are all driven by the serpentine belt. Open the hood and feel along the belt with your hands (you can use a flashlight if need be) when the engine is off to find cracks or for any signs of separation of the belt plies. Be sure to check for fraying, which makes it look glossy. You will therefore have to twist it in order to inspect both sides of it. Ribs under the belt are also supposed to be studied. No one deepness should be higher than another on all surfaces. There's nothing you can do about tensioning since it's done by tensioner assembly and there's no way it is adjustable. It is necessary to change on time those belts which were marked in indicated car service manual or if they are spoiled or worn out already. To put on new belt rotate tensioner anticlockwise into slackening position till old one could be removed out from auxiliary units, then slowly release tensioner piston backward down where from you have taken out your used accessory part once more but in forward direction this time towards other engine components that have been mentioned before with their name provided over each pulley particularly at that exact moment when another serpentine item got inserted just like we've told you previously yet without forgetting about letting go of this special mechanism again immediately after doing such things correctly twice as many times! This decal shows how to install drive belts for different models on radiator shroud. In case you don't know where that's located, try looking at radiator shroud underdrive belt routing diagram.

The tension of the belt is maintained by the tensioner assembly and isn't adjustable.
