Adhesive Coated Fasteners

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

These fasteners accomplish the thread interface by the presence of a thread-locking compound on the fastener threads.

Refer to the appropriate repair procedure in order to determine if the fastener may be reused and the applicable thread-locking compound to apply to the fastener.
