There’s a leak coming from the overflow bottle on the fan, I’m planning on going to the junk yard for the fenders, hood, bumpers, etc and buying a new radiator and maybe condenser?
You don't need to any flushing got flushed at the hit ? Put a cable around that blue side core support tie cable around tree car in neutral now push car away from tree . You push n rock n bounce cable against that blus support until it looks like other side . Ben here done this twice here have 09 ya cannot tell it's been done cept by seeing the blk from sheet metal take off on gold car . Couple hours the whole front back together
An insurance company would total that; but if you've got the know-how and time to fix it. Go for it. The energy absorbent crumple zone in that corner has probably been compressed. Hopefully the alignment hasn't been tweaked. Good Luck......
Radiator support (the one across the top) is bent at the top. The OP may want to pay a body shop to examine it and see how bent up the "frame" is. Not a lot of point in fixing the body work if the car won't ever drive straight again.
