The Cummins temperature switch is a normally open (NO) or normally closed (NC) device that operates based on temperature rise. When engine coolant or oil reaches a specified critical temperature, the switch changes state — often triggering an alarm, fan, or engine protection circuit.

It is used in mechanical engines, gensets, and some electronic engine protection systems where digital sensors are not required.

Part numbers and engine names (e.g., Cummins®, QSB, KTA) are used only for identification. We are not an authorized distributor of Cummins Inc. Unless stated otherwise, the temperature switch offered may be an aftermarket or OEM-compatible product.

The 1-13770089-1 Thermostat is designed for the Isuzu 6WF1 diesel engine used in Isuzu CXZ2003 trucks. It regulates coolant flow between the engine and radiator to maintain the correct operating temperature, helping improve engine efficiency, prevent overheating, and extend engine life.

Manufactured to meet OEM specifications, this thermostat provides reliable performance for heavy-duty diesel engine applications.

All brand names, part numbers, and engine references (e.g., Isuzu®, 6WF1, CXZ2003, 1-13770089-1) are used for identification purposes only. We are not an authorized distributor of Isuzu Motors. Parts supplied may be OEM genuine or high-quality aftermarket replacements. Please verify compatibility with your engine model and vehicle before ordering.
