The serpentine sash is referred to as the unmarried guide zone used in most cars nowadays. Contain the correct tool onto the tensioner and turn in the correct direction--clockwise or counterclockwise--to release the tension on the belt. Tensioners will only move in one direction and will bind in the other. Any tensioner that uses the bolt head of the pulley will require clockwise motion as turning the bolt head counterclockwise would unthread the bolt from the engine block.5.
Instructions
1. Acquisition the routing diagram. Many diagrams are located on the underside of the hood or on the engine frame condemn near the sash stop. In the advent there is no routing diagram, touch to the repair instruction or clarify a diagram of your own before removing the band.
2. Fix the tensioner pulley. Most routing diagrams Testament acknowledge the objective of the tensioner pulley and which plan to measure it to help tension on the band. While most tensioners are moved clockwise, there are exceptions. Mention to the repair handbook for the equitable procedure.
3. Scrutinize the tensioner to decide the fair factor to custom to modification it and then Proceeds tension on the girdle. Some tensioners catch a box-end wrench or ratchet and socket directly on the bolt sense of the pulley, on the other hand many others obtain a square manage thing, such as a ratchet without a socket or a serpentine region part with an adapter to berth in the gap and turn the tensioner.
4. Older cars had multiple countervail pulleys managed by the crankshaft that required two to four V-belts to capability the antithetic accessories. The serpentine cestuses snakes along the centred pulleys of nowadays's engines and operates all of the accessories needed. Serpentine belts again appropriateness an automatic tensioner, which is a spring-loaded pulley that applies the exactly tension setting to the zone and eliminates the duty to re-tension the zone.
Remove the serpentine belt from the most accessible pulley while still holding the tool on the tensioner.
6. Remove the old serpentine belt. Some belts may wind up wrapped around the arbor of the fan. If this is the case, it requires tucking the belt under the fan shroud and then up and over the fan inside the shroud to remove. Installation of the new belt may require the reversal of this procedure.
7. Compare the length and rib count of the old belt to the new belt before installing to ensure the correct belt is being replaced.
8. Reinstall the new belt and ensure that the ribs of the belts align into the grooves of the individual pulleys. Wrap the belt around the lower, harder-to-reach pulleys first and then use the diagram to snake it around the others. Reapply the tension release of the belt tensioner again and then place the belt back onto the most accessible pulley. A belt being removed or replaced onto the accessible pulley is going to be somewhat tight, but should fit on without being forced onto the pulley. If excessive force is needed, either the wrong size belt is being put on or the alignment of the ribs and grooves is incorrect.
9. Remove all the tools and the old belt from the engine compartment and then test-start the vehicle to make sure the belt is installed properly.
