A system and method to provide an operator indication for filling a reductant tank is provided. A first temperature sensor and a second temperature sensor receives a first signal and a second signal indicative of a coolant temperature and an ambient temperature associated with the reductant tank, respectively. Further, a controller determines a rate of change of temperature of the coolant based on the first signal and the second signal. The controller predicts thawing time for the fill valve based on the rate of change of the temperature of the coolant. The controller provides a first indication to the operator of a ready-to-fill status of the reductant tank based on the thawing time. The controller receives a third signal indicating a level of reductant in the reductant tank from a level sensor to identify a tank-full status of the reductant tank and to provide a second indication to the operator.
