Description
This is a coolant temperature sensor for Freightliner chassis applications, replacing Freightliner 22-54800-000. The sensor uses a 1/2 in – 14 NPT pipe thread, a 2-pin rectangular gauge-side connector, and is supplied by PAI Industries as PAI 740230. Common fitments include the Freightliner FLD 112 / 120 / 132 conventional, plus Columbia and Cascadia chassis using the same sender feed.

Applications
This coolant temperature sensor fits the following Freightliner chassis:
- Freightliner FLD 112, FLD 120, FLD 132 conventional (1993–2003)
- Freightliner Columbia (2000–2012)
- Freightliner Cascadia (2008–2012, dash gauge feed using 22-54800 sensor)
Confirm the connector shape, pin count, and thread size on the existing sensor before ordering. The 22-54800-000 and 22-54800-001 are physically similar but not interchangeable on every chassis.
