Summary of specific components and tightening torques
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Screws coated with locking fluid or sealant must be replaced with new when reinstalled.
Always use new screws and nuts when angle tightening. Any exceptions to this rule will be indicated in the method.
