Preparing oxygen sensor
NOTE:
TECHNICAL INFORMATION
Grease the threads of new oxygen sensors thinly and evenly.
For oxygen sensors that are reused, the following should be observed:
Thinly and evenly grease the oxygen sensor on the thread only. Do not clean the part of the oxygen sensor that does not protrude into the exhaust line (sensor ceramics) and do not grease.
