So I took a real close look no the threads and it looks like I might have damaged some of it yesterday. Tried fixing it with a flat head but no luck. Called my local dealer and they said they could get one by Tuesday. Thankfully I have another car or I would have been really screwed

I'm changing my coolant for the first time today, and for the life of me I can't get the radiator drain plug screwed back in! I got the plug out fine with a phillips head but for some reason it just doesn't go back in. Any ideas? Thanks
