Oxygen Sensors Overview

Oxygen Sensors Overview

• Coat new oxygen sensors with an assembly paste.

• On a used oxygen sensor, only the thread may be coated with hot bolt paste; Hot Bolt Paste, refer to the Electronic Parts Catalog (ETKA).

• Assembly paste or hot bolt paste must not get into the slits on the oxygen sensor body.
