Description of Change: Improved coolant flow switches are available for these engines. The improved coolant flow switches are more resistant to damage that can be caused by corrosion. The corrosion can result from poorly maintained coolant. The corrosion can result from coolant that does not meet Caterpillar specifications. The improved coolant flow switches will provide increased service life.
Adaptable To: The following table identifies the improved coolant flow switches and the corresponding earlier coolant flow switches.
