Antifreeze for Subaru XV and Crosstrek
The XV and Crosstrek are the same car under different names for different markets. The FB20 engine is newer than the EJ, but it follows the same all-aluminium logic and needs the same protection.

Photographs come from the manufacturer's official materials.
Cooling system volume (litres) roughly six to seven litres
The e-Boxer hybrid models
The hybrid versions of the XV and Crosstrek, the e-Boxer, have additional cooling for the power electronics. If your car is a hybrid, check the manual for the specification listed for each circuit before filling anything.
That is not excess caution. Putting the wrong fluid into a hybrid power-electronics loop is a far more expensive mistake than a bottle of antifreeze costs.

Do the XV and Crosstrek need different fluids?
