I'm pretty sure this is a bad radiator, but want to confirm with you guys 100%. I could get a pressure tester and maybe should, but want to see if it's really obvious. I've just never diagnosed a radiator before. 99 Suburban, overheating pretty quickly. No big puddle of coolant on the floor, but strong smell. Then I noticed that at the base of the radiator, I think it's called radiator support, it's like a plastic "tray" that the radiator sits on/in, and it is full of coolant. Also the fan has coolant sitting in it. None of the hoses or fittings coming from the radiator seem to have leaks, so is this open and shut case of needing a new radiator? Thanks!
