Guide: Volvo V70 D5 Auxiliary Belt, Idler and Tensioner Replacement

Removal

Remove the plastic engine cover by just pulling it up and off. To remove the belt, the tension must be released first. The tensioner is an automatic spring-loaded type, which can be released with a ratchet and suitable fitting. On newer replacement tensioners, there is a Torx hole on the swinging body of the tensioner, which you can put a T-60 Torx plug into on the end of a ratchet to lever the tensioner away from the belt:

There is a locking hole in the tensioner body to allow a pin (or similar) to be inserted in the released position to keep the tension off the belt, which is very handy during replacement. the below image shows the (old) tensioner locked in position. You can also see in this picture the T-60 hole to the left of the locking hole on the front face that you would use to lever the tensioner.

The box emulates a CD changer to allow music on a USB drive or SD card to be accessed from the car stereo as if it were CDs in the changer.

Removing the Head Unit

Just be bloody careful not to damage the surrounding plastic trim(not sure if this is here on all cars, if not something else should be in its place that can equally be prised out).

In the gap behind where the pen clip was, you can now access two screws that secure the climate control unit:
