Methods and systems are provided for rapidly cooling an engine system of a vehicle at vehicle-off events. In one example, a method may include cooling the engine system via selecting whether to rotate a cooling fan in a first direction or a second direction based on an indication of whether temperature of the engine system decays at a faster rate under conditions where the cooling fan is rotated in the first direction as compared to the second direction, or vice versa. In this way, diagnostics that rely on static, low-noise conditions may be conducted for vehicle-off conditions that are not sufficiently long to allow for sufficient engine system cooling in a timeframe of the vehicle-off condition.
