Bobcat 6718415 Temperature Sensor Sender

The Bobcat 6718415 temperature sender is an engine coolant temperature sensor designed to monitor engine operating temperature and transmit data to the gauge cluster or ECU. It features a threaded brass or stainless steel probe body with a 0.826 inch (approx. 21 mm) outer diameter thread for direct installation into the engine block or cylinder head coolant passage. The sensor operates on a negative temperature coefficient (NTC) resistance principle, providing variable resistance output corresponding to coolant temperature changes. This component is critical for engine thermal management, overheat protection, and cold-start enrichment strategies. It is engineered to withstand vibration, pressure fluctuations, and chemical exposure inherent in heavy equipment cooling systems.
