Pro Tip: Never rely on a generic "Chevy V8" diagram. The C15 uses a compared to old diesels. Some older mechanics accidentally swap the radiator hoses—resulting in $15,000 worth of melted pistons within 50 miles.

A thermostat that sticks closed will cause rapid overheating, while one that sticks open will prevent the engine from reaching efficient operating temperatures. C15 Engine Cooling System Overview | PDF | Coolant - Scribd Cat C15 Coolant Flow Diagram

Master the flow, master the C15.

Once the coolant hits its target temperature (typically 180°F to 190°F), the regulator opens. The bypass closes, and the hot coolant is directed through the upper radiator hose into the top of the radiator to be cooled by airflow. Auxiliary Loops: Turbo and Aftercooler Pro Tip: Never rely on a generic "Chevy V8" diagram

The C15 uses a pressurized cooling system designed to operate safely above the boiling point of water while preventing pump cavitation. The journey of the coolant follows a specific, logical sequence: A thermostat that sticks closed will cause rapid
