1. A method for monitoring a fluid line in a vehicle, comprising:
receiving, by one or more processors, vehicle state data of the vehicle;
determining, by the one or more processors, a recommended flow rate of a coolant based on the vehicle state data;
determining, by the one or more processors, vibration signal thresholds based on the vehicle state data and the recommended flow rate;
operating a pump of the vehicle to flow the coolant through the fluid line at the recommended flow rate to remove heat generated by an electronic device of the vehicle, wherein the recommended flow rate is configured to maintain the electronic device below a predetermined temperature;
determining, by the one or more processors, whether the flow of the coolant through the fluid line is stable;
sensing, with a sensing device of the vehicle, vibrations in the fluid line caused by the flow of the coolant therein;
determining, by the one or more processors, one or more signal characteristics of the vibrations sensed with the sensing device while the flow of the coolant through the fluid line was stable; and
initiating, by the one or more processors, a remedial action based on a comparison of the one or more signal characteristics of the vibrations to the vibration signal thresholds.
