Antifreeze for Toyota Aqua and Prius C
The Aqua, sold as the Prius C in the US, arrives in Georgia in numbers from Japanese auctions. It repeats the Prius logic in a smaller package: two cooling circuits, pink factory fluid and an inverter with its own reservoir.
Photographs come from the manufacturer's official materials.
Cooling system volume (litres) engine roughly four litres, plus a separate inverter circuit
A small system with the same requirements
The Aqua's engine circuit is smaller than the Prius's, but the chemical requirement is identical and the inverter circuit is just as sensitive to deposits.
Our advice is the same as for the Prius. If you are doing a full flush, the blue is valid by specification, and if nothing is urgent, Zerex Asian Red is the more direct match and is coming soon.
