A:
You can not apply thread sealant to sensor threads. The sensor is coated at the factory and applying an additional sealant will affect the sensor's ability to detect detonation.

A:
Hot engine coolant may cause severe burns. Although the cooling system has been drained, coolant remains in the engine water jacket. This coolant will drain with the removal of the knock sensor.
