Belt check - Working on your vehicle - Maintenance and servicing - Volvo XC90 Owners Manual - Volvo XC90

Check the belt regularly to make sure it is in good condition and is clean. A worn or dirty belt can cause poor cooling and low alternator output as well as impair the operation of the power steering and the air conditioning unit.

NOTE
The drive belt is equipped with a self-tensioning mechanism and requires no adjustment between changes.

WARNING
The engine must not be running when this check is performed.
