Thermostat is bad. Change the Thermostat and Bleed out the system.

S2ks cooling systems typically stay completely clean...it would be a VERY slim chance you have a clog.

I'll bet the bank you are low on coolant due to a small leak.

Faulty radiator cap will do that too. Are you running a mishimoto radiator cap by chance- if so get rid of it.

The car is not low on coolent. I tried to bleed the coolent many many times thinking there was air in the system but everything I start driving the car it will start to over heat. But no matter how hard or long u drive the car the lower radiator hose will still be cold
