I'm replacing my radiator with a new one that will be here tomorrow. Should be easy? Just a few bolts and hoses right? Nope. I got all the hoses off and all the bolts off except for the last two. They are rounded off and I can't get anything to bite on them in the tight space. I figured I'd just pull off the whole grill and that was going well until I found out there's two hoses that I think belong to the AC compressor? 10mm too big, 9mm way too small, 3/8 just a tad too small so I'm thinking they are 10mm that got rounded off from the last installer. Any ideas?
