Which way do you turn a tensioner pulley?
Rotate the pulley on the belt tensioner counterclockwise to relieve the tension of the belt with the proper sized socket and ratchet. Slide the belt off of the belt tensioner pulley. Let the belt hang down.
What are the two types of belt tensioners?
There are two types of tensioner pulleys that provide the tension on an engine’s accessory belt or belts. One type is self-adjusting; the other requires manual adjustment. The self-adjusting pulley is spring-loaded and provides its own tension.
Should my belt tensioner be moving?
The tensioner arm should move smoothly and freely. Solution: If you notice a binding, sticking or grinding tensioner arm, the tensioner should be replaced.
How tight should tensioner bolt?
When twisted either way from the middle, the tension in the belt must not be more than 12 inch. The belt is too tight if it is twisted more. The positions do not work for the vehicle.
Is it easy to replace a serpentine belt?
Serpentine belt replacement is easy because today’s automatic drive belt tensioners eliminate the need to loosen bolts or pry components into position for retensioning. Just rotate the tensioner, remove the old belt and install a new one. When the belt ribs are seated into the pulley grooves, release the tensioner and you’re done.
How is the tension set on a serpentine belt?
Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.
Do you have to change the SERP belt?
Press the gauge into a belt groove. As long as the gauge sits above the ribs, the belt is good. If it slides down so it’s even with the rib, the serp belt is worn and must be replaced. 15 Car Problems You Can Diagnose (and Fix!)
Where do I find the serpentine belt routing diagram?
Find the serpentine belt routing diagram. Many cars come with a sticker in the engine bay that shows exactly how the serpentine belt is supposed to be routed through the various pulleys on the engine. If your vehicle does not have a sticker, you will need to find another way to remember how the belt should be run.
