What is the purpose of a belt tensioner assembly?

A belt tensioner assembly keeps the accessory drive belt at the correct tension. This is important to prevent the belt from slipping, which ensures that components like the alternator, power steering pump, and air conditioning compressor operate efficiently.

Does this tensioner assembly come with a new belt?

This part is the tensioner assembly itself, which includes the tensioner arm and pulley. It does not include the accessory drive belt. You will need to purchase the belt separately if you are replacing it as well.

How difficult is it to install this belt tensioner?

Replacing a belt tensioner is typically a moderate job. It usually involves removing the accessory drive belt, unbolting the old tensioner, and installing the new one, then reinstalling the belt. Refer to the manufacturer's installation instructions for specific details.
