hi all. iv noticed that after my engine(b16a) has cooled down the radiator hoses go flat due to some air issue, cause when i take the rad cap off the hoses spring back too there normal shape. iv bled the system many times and got new rad hoses. im not loosing coolant and i never over heat. any ideas or is it normal? just never noticed it with my other cars

You should replace your radiator cap.

Sounds like it is not able to pull coolant out of the reservoir. Make sure nothing in that small hose or where it connects to the rad is clogged. Check the cap too

Your radiator cap has a pressure membrane in it, and if its not working, it will allow pressure to build to high.
