TORQUE SPECIFICATIONS FOR ENGINE-MOUNTED SENSORS
ASET™ AC ENGINE-MOUNTED SENSORS
Overtorquing a sensor or sensor mounting screw
can result in sensor breakage or thread damage.
Description Sensor and Sensor Mounting Hardware Sensor Threads Mounting Torque
Air Temperature Sensor
(wide range and fast
response)
64MT450 sensor only; sensor is used in three locations:
앫 Compressor discharge temperature
앫 CMCAC outlet temperature
앫 Inlet manifold temperature
Reinstallation of this sensor requires application of
stainless steel pipe thread sealing tape. This tape is
identified as Mill-Ross type TF5-28, catalog number
70981-st, size 1/2" x 260".
