The Alltrux ATX22094 Coolant Temperature Sensor replaces OEM 1077574 and is designed as a service replacement for heavy-duty truck engine cooling systems. This sensor monitors coolant temperature and provides accurate input to the vehicle’s electronic control system, supporting proper engine protection, efficient operation, and consistent performance in fleet and vocational environments. Coolant temperature sensors play a critical role in engine management by helping regulate cooling fan operation, warning systems, and engine protection strategies. As original sensors wear electrically, become contaminated, or fail due to heat and vibration, inaccurate readings and potential overheating risks can occur. Replacing worn coolant temperature sensors helps restore precise temperature monitoring, improve engine safety, and reduce unplanned downtime.
