How serious is a bad belt tensioner?

How do you loosen a tensioner bolt?

Turn the bolt head in the center of the spring-loaded arm of the belt tensioner counterclockwise with a ratchet and socket to loosen the bolt. The tensioner will rotate freely before it comes to a stop. When the spring-loaded arm comes to a stop, continue to turn the bolt until the bolt loosens.

How do I know if my belt tensioner needs replacing?

Appearance: Cycle the tensioner (mounted on the engine) through the entire range of motion (from stop to stop) by applying torque to the arm with a wrench. The tensioner arm should move smoothly and freely. Solution: If you notice a binding, sticking or grinding tensioner arm, the tensioner should be replaced.

Can I drive without belt tensioner?

When the tensioner fails, the serpentine belt will slip off and break. When this happens, the alternator, power steering pump, and AC compressor will stop working. Since there is no belt turning the pulley, the battery light will turn on, and steering will be difficult. The AC compressor will also stop working as well.

How do I loosen the alternator tensioner?

Locate the adjusting bolt bracket on an import vehicle to loosen the tensioner. Most often this bracket is located near the alternator. Loosen the bolt with a ratchet and socket until tension is relieved on the belt.
