Using nickel anti-seize when installing thermocouples on an engine prevents seizure of the thermocouple in the fitting. Loctite Nickel Anti-Seize prevents corrosion, seizing, and galling in temperature up to 1315° C (2400° F).

Part number 337-7965 Anti-seize is no longer available through the Cat Parts System. The anti-seize can be ordered through the Loctite website at the following address :

• http://useloctite.com/caterpillar/

• Item 77164

The use of nickel anti-seize is effective for all engines that use thermocouples, not only the above serial numbers.
