i had to add the blue liquid windshield stuff this evening and i noticed that the uppper radiator hose had squashed itself in the middle. when i loosened the radiator cap, the hose unsquased itself into its normal round self.

i thought this was weird so i checked it again after driving it and it was once again vaccuum squashed. i had to relieve the pressure by loosening the radiator cap again.

any ideas?
