How to Tighten a Serpentine Belt

1. Open the hood and locate the adjustment screw that controls tension on the serpentine belt.
2. Place the socket end of the socket wrench over the wing-nut and turn clockwise to apply tension.
3. Check the tension of the belt periodically.
4. Do a secondary check of the belt tension.

What keeps the serpentine belt tight?

Most tensioners feature an internal spring and pulley, which applies needed force against the serpentine belt to keep it tight. If there is not enough tension, a belt can slip, squeal or run hot.

How long does it take to tighten a fan belt?

Introduction. Automatic belt tensioners, standard in most cars now, make changing a serpentine belt a simple DIY repair. Follow the clear photos and step-by-step instructions and you’ll be done in 15 minutes.

How do you know if your drive belt is loose?

A loose drive belt will often be noisy, squeaking a bit, or emitting a high-pitched squeal. The most obvious sign of a loose drive belt, though, is in its appearance and tension. A loose belt, simply stated, looks and feels loose.

How tight should fan belts be?

For most vehicles, the belt should not be able to be pressed down more than ½ inch. If it can be pressed lower, then the belt is too loose.

What happens if your belt is too tight on your car?

If the belt is too tight, it will cause excessive side loads and overheat the bearings. This in turn causes noise, decreased output and even the seizing of the alternator. If the belt is too loose, it will cause the alternator to slip. This slipping can cause the alternator and the battery to work harder.

How is belt tension properly checked?

Belt tension is measured by plucking the belt span while holding a sensor close by. Belt tension is adjusted until the belt span frequency, or measured tension level is within manufacturer’s recommendations.

How do you tension a chain and belt?

To adjust chain tension, loosen the bolts that fasten the motor base to mounting angles on both sides. Tighten take-up bolts until desired chain tension is reached. Do not over-tighten. A good rule of thumb is 1/4″ deflection in the chain between the sprockets.

What will happen if the belt is not replaced?

If the serpentine belt completely fails and breaks, then your car will break down. In addition, you will notice a loss of power steering, the air conditioning will not work, and the engine will no longer be able to be cooled like it should be.

What is belt tension?

Belt tension is determined by measuring the force to deflect the belt a given distance per inch (or mm) of pulley. Timing belts need only adequate tension to keep the belt in contact with the pulley.

What do tension members do in V belts?

Friction drive belts rely on the friction between the belt and pulley to transmit power. They require tension to maintain the right amount of friction. Flat belts are the purest form of friction drive while V-belts have a friction multiplying effect because of wedging action on the pulley.

What is belt tension and why is it important?

It supplies tension to engine belts. When functioning the entire system properly keeps the vehicle running smoothly, but if any one part of the system fails, it could affect the alternator. Subsequently, the battery, the engine, and the car could break down.
