Coolant and Coolant additives

[InV-Rager]

Hi,

My 2000 Subaru Legacy GTB recently blew a radiator. I have bought a new radiator for it, but unsure what coolant I should buy for it and if coolant additive is necessary.

Thanks in advance.

I typically use the Subaru premixed blue coolant, I buy it from the local dealership.
