I bought a 77 ranchero a month ago and in preparation to drive it i had the radiator flushed. Turns out it was filled with water, well it was flushed and filled at the quicklube. I didn't run it after that but did check the levels after that and it was fine for a bit. Then a week later i go check, and there is a faint green stripe running the length of the unit. When I opened the cap the level had dropped. Crawling underneath on the passenger side there was a small hole plugged with the peice of outer shell that had broke and got pushed up in the bottom.
What should i expect to pay for a patch or replacement unit, and can you advise any shops to go to?
