Installation Instructions
1. Remove protector cap just prior to installation
2. If not already coated, apply (enclosed) anti-seize to oxygen sensor threads.
3. Install sensor body ensuring lead wire is not twisted or bent
4. Install all sensors with new gasket supplied and torque to proper specs as below:
M18 sensors - Install finger tight then 1/2-3/4 turn with wrench / O2 sensor socket 26-33ft. lbs.
M12 sensors - Install finger tight then 3/4 - 1 turn with wrench / O2 sensor socket 13.2 -17ft. lbs.
A) Flanged applications - (where flange is NOT already installed on sensor) Install flange to exhaust manifold first, then mount sensor in flange
(A copper gasket is bonded to the flange & no additional gasket is required)
B) Flanged applications - (where flange is already installed on sensor)
(it is important to use the supplied gasket before installing sensor)
5. Connect and route lead wire as originally installed
Warning: Anti-seize compound may cause irritation to the skin or eyes. In case of contact, wash affected area with soap and water. In case of eye contact, flush with water for 15 minutes.
