Just installed brand new radiator after a minor fender bender... got all the hoses and clamps installed and was excited to fill up the system with coolant and warm it up... unfortunately as soon as i added coolant the coolant poured directly out of the bottom as fast as gravity could pull it. i mean immediately upon adding coolant 0% remained in the system... i checked all my hoses and clamps and they are all perfectly sealed and dry... is this a bad radiator? please help!?!
