According to one aspect, a thermal system of a vehicle which provides cooling to within the vehicle, e.g., within a driver and passenger carrying cabin or compartment, is effectively leveraged to provide cooling capabilities to autonomous vehicle systems. Some coolant flowing through a coolant loop included in the thermal system of a vehicle may be diverted to an offshoot loop which provides cooling to coolant included in a coolant loop configured to cool autonomous vehicle systems, e.g., a compute system that is part of an autonomous vehicle. The coolant from the thermal system of the vehicle may flow past coolant from the coolant loop configured to cool autonomous vehicle systems, and the cooled coolant from the coolant loop configured to cool the autonomous vehicle systems may flow near the autonomous vehicle systems to cool the autonomous vehicle systems.
