Depending on the vehicle, the serpentine belt may drive the alternator, A/C compressor, power-steering pump, and water pump. A failed belt can cause loss of charging, steering assist, or cooling.
Common symptoms
What we check
Serpentine-belt replacement is a common mobile repair on many vehicles. We inspect the tensioner and pulleys whenever the belt is serviced.
Replacing only the belt while leaving a worn tensioner or pulley can lead to noise, belt damage, or repeat failure.
A note on shop equipment
Some repairs cannot be completed safely at a mobile location. After the diagnostic, we will tell you whether the work can be done on-site or whether shop equipment is required, before any repair begins.
