Specs At A Glance

Good To Know

Q: What are the signs the tensioner O-ring has failed? A: Oil residue around the tensioner base or drips under the engine after use point to a worn seal, confirmed by a hardened or flattened O-ring at removal.

Q: Is this O-ring enough on its own for a tensioner replacement? A: This O-ring covers the seal at the tensioner mount, while the tensioner assembly and related gaskets are separate parts, so inspect everything during the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
