Where is the fan belt tensioner located?
The belt tensioner is on the front of the engine, between the crankshaft and alternator pulleys.
What sizes do fan belts come in?
First, to determine what type of belt is on your fan, measure the width of the belt. Most fan belts are A type belts with a measurement of 1/2″. If the fan belt measures 5/8″ it is classified as a type B belt.
How often do fan belts need to be replaced?
60,000 to 100,000 miles
How often does a serpentine belt need to be replaced? Serpentine belts are built to last—much longer than before because of advancements in rubber technology. Under ideal conditions, a belt should stick with you for an average of 60,000 to 100,000 miles.
What’s the best way to adjust the fan belt?
Use a wooden lever (a hammer handle will do) between the pulley and engine block to get the right tension. While the belt is held under tension, tighten the clamp bolt. Re-check the tension and if it is correct re-tighten the hinge fixings.
What are the symptoms of a bad fan belt adjuster?
Unusual belt wear. Another symptom of a potential problem with the fan belt adjuster is unusual belt wear. If the fan belt adjuster pulley has any sort of issue it can cause unusual and accelerated wear on the belt. A bad pulley can cause fraying on the edges of the belt, and in severe cases can even cause it to break.
How does the fan belt affect the engine?
Mechanically, it can be assumed that the tension of the fan belt to its pulley has a lot to do with the engine speed. If the tension of the belt is weak it can reduce the pulley rotational speed due to the slip arising from the micro space between the belt and its pulley.
Can a bad pulley cause a fan belt to break?
If the fan belt adjuster pulley has any sort of issue it can cause unusual and accelerated wear on the belt. A bad pulley can cause fraying on the edges of the belt, and in severe cases can even cause it to break.
