If that hose were leaking you would see signs of fluid around it. Radiator fluid is black light reactive. A quick way to find leaks is to whip out a black light and start hunting around. If it glows, its a leak. Your radiator may also be restricted, so when you added fluid it seemed like it was full and over night it worked its way past the restriction. I'd do a radiator flush and then top off the radiator and bleed it properly. Good luck...

 

yea theres fluid around it but I havent climed under there to see if its the hose or the radiator its self. im thinking its the hose. and the black light wouldnt work cause apparently the idiot i bought it from put straight water in it
