Default 2015 wrx coolant change help

Hi i was wondering if any one has done this and has any intstructions. Like whats the easiest way to drain the radiator. I bought the car used and would like to change all the fluids since idk what is in it etc. I am looking at changing out the coolant to change to amsoil brand. I bought the coolant already thinking it would be as easy as older wrx's but cant find where the radiator drains and the best way to get to it.

It is very unlikely that anyone has changed the factory coolant in a '15. It's good for a very long time and wouldn't be part of any scheduled maintenance unless a previous owner was really sold a bill of goods by a shop out for money.
I'd just leave it alone.

check a factory service manual. its not as simple as a drain and refill like it was 20 years ago. you have to get every last bit of air out or else you can end up with serious mechanical issues.

What benefit do you think there is to switching to different coolant?

Super coolant is designed to last over 130k miles.

The manual doesent have how to change it other then it says to take it to a service station. The coolant that is in it isnt the subaru coolant as its more of a orange color then blue thats why i would like to change it as i dont know what kind of coolant or if there is additives in it etc.

So, I am going to guess that it is no different than before - pull the lower radiator hose.

You can always use a funnel and a 5 gallon bucket, just pull the hose off slowly to capture the fluid in the funnel/bucket

The drain plug is in a stupid place that can't be easily reached

A 15 wrx with coolant changed already? Yikes.

Honestly, I'd take it to a shop that will not only drain it, but flush it completely. Drain it, run water through it, drain it more, and fill it with the correct stuff.

Good luck with that car.
