Question

the belt causing drive belt squeal can be spotted by:

a. replacing the tensioner.

b. squirting some water onto the belt.

c. turning on the air conditioner.

d. loosening the belt.

Explanation:

Squirting water on the drive - belt is a common method to identify the belt causing a squeal. If the squeal stops when water is applied, that is the belt causing the issue. Replacing the tensioner is a fix, not a detection method. Turning on the air - conditioner may stress the belt but doesn't directly spot the squealing belt. Loosening the belt is not a way to spot the squealing belt and may cause more problems.

Answer:

B. Squirting some water onto the belt.
