Belt Tensioner Replacement
A rattling noise on startup usually means the tensioner, not the belt.
The belt tensioner keeps constant pressure on your serpentine belt. When its bearing wears out, you'll hear rattling or squealing, especially on startup, and the belt can slip or come loose. We replace the tensioner and inspect the belt together.

Belt Tensioner — FAQ
How is this different from just replacing the belt?+
The tensioner is the spring-loaded pulley that keeps the belt tight — if it's worn, a new belt alone won't fix the noise.
Is this an urgent repair?+
A failing tensioner can lead to belt slippage, so it's best addressed as soon as you notice the noise.
