Product Overview
An implausible coolant-temperature reading, an overheating warning on a cold engine, or no temperature change as the machine warms can point to a failed sender after the wiring and cooling system are checked.
This replacement sensor restores the temperature signal used for engine monitoring. Accurate coolant-temperature feedback helps the operator catch real overheating while avoiding false warnings caused by a failed sender.
