In that situation, and only then, I'd give the sanding a shot before replacing the radiator...but it's the first I've heard of that issue here...and I read a lot here. But, that said, my concern was whether he had the decent skill. If you're sanding plastic to then have a pressure seal from o-ring, you'd need to be very careful and finish with a very fine sandpaper.
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
