Pop the hood and find the belt routing diagram on high of the fan shroud. If there is no such thing as a belt routing diagram, take a pen and notepad and draw out the precise course by which the belt is routed throughout the pulleys.
Find the belt tensioner. The belt tensioner on the 4.3, 5.0 and 5.7 liter is positioned immediately beneath the alternator. The belt tensioner on the 4.8, 5.3, 6.0 and 6.2 liter is on the highest front of the engine on to the left of the loafer pulley. The belt tensioner on the 6.5 liter is positioned on the front heart a part of the engine, and the belt tensioner on the 6.6 liter engine is positioned on the far left-hand facet of the engine about midway up. The belt tensioner on the 7.four liter is positioned instantly under the alternator, and the belt tensioner on the eight.1 liter is on to the precise of the center water pump pulley.

Slide the belt off of the belt tensioner then slide the belt off of the remaining pulleys. Pull the belt out of the engine compartment and set it to the facet. Place the brand new belt inside the engine compartment. Put the belt on the underside crankshaft pulley first, then observe the belt routing diagram for routing the belt throughout the remaining pulleys. Depart the belt tensioner for final. This may make it simpler so that you can put the belt on the belt tensioner with one hand whereas holding the tensioner with the opposite.
Use the pull bar and socket to alleviate the strain off of the belt tensioner pulley. Route the belt on the belt tensioner precisely as proven by the belt routing diagram. Then launch the belt tensioner in order that the belt tensioner pulley will put the correct quantity of stress on the belt. Examine the belt to be sure that the belt is strictly routed as within the diagram and that the belt is totally seated within the pulleys.
Crank the engine and examine the belt because the engine is operating. Be sure that the belt is working evenly on the belt tensioner. Additionally ensure that the belt stays seated within the pulleys whereas the engine is operating. Flip the engine off and shut the hood.
