Coolant: Description and Operation
Operation
OPERATION
Coolant flows through the engine block, cylinder head, absorbing the heat from the engine, then flows to the radiator where the cooling fins in the
radiator transfers the heat from the coolant to the atmosphere. On the 6.7L diesel engine, coolant also flows through the EGR cooler and turbocharger
actuator. During cold weather the ethylene-glycol or propylene-glycol coolant prevents water present in the cooling system from freezing within
temperatures indicated by mixture ratio of coolant to water.
