A method is provided for testing the performance of a vehicle-mounted heat exchanger and determining whether debris is preventing air from efficiently passing through the heat exchanger. To test performance, after the vehicle is traveling faster than a preset minimum speed, the power to the DC fan motor that is adjacent to the heat exchanger is interrupted and the back EMF of the motor is used to determine fan motor speed. As rotation of the unpowered fan motor is due to the air flowing through the heat exchanger, the rate of fan rotation is used to indicate the relative health of the heat exchanger. If the rotation of the fan motor indicates insufficient air flow, then a notification message (e.g., visual or auditory warning indicator) is transmitted. If the test indicates sufficient air flow, normal operation of the fan motor is re-initiated and power is re-connected to the motor. 1.

Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time.
