cavity.
Install the sensor hand tight. Remove the sensor
and check thermal joint compound coverage on
the sensor probe.
Thermal joint compound should cover at least
75% of the length to the sensor probe.
SLOWLY tighten temperature sensor to a torque
of 12 to 18 in. lbs. (1.35 to 2.0 N·m). Wait 10 min-
utes for trapped air to bleed from cavity. Thermal
compound may seep past threads. Re tighten
