Summary Of Tightening Torques For Specific Components
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Screws coated with locking fluid or sealant must always be replaced with new screws during reinstallation.
Always use new screws and nuts when angle tightening. Any exceptions to this rule will be indicated in the method.
