Re: 82 green oxidation on radiator (GDaina)
yep, time to get a new one...green means it's leaking coolant
open the cap. if you see stalagmites (or is it the stalagtites) time to replace the radiator. I had a similar problem on my 79. had the orginal recored using a core with extra cooling fins per inch. I have had no problems since.

Re: 82 green oxidation on radiator (mannymen)
what are stalagmites (or is it the stalagtites)?
The difference is stalagmites are pointing up, say from a cave floor and stalagtites are pointing down, say from a cave ceiling. 8th grade science class.
Or it could be the reverse :D

Copper oxide is green. Could be normal corrosion. Spray on Simple Green, flush with water and re-paint with a semi-gloss black heat paint.
These roofs are copper.

I suspect if the poster cleans up the green area and hits it with some paint he will be good for quite some time. My 1979 rad is still fine after 24 years. A pressure test might be advised to get a true reading before next summer comes. He would not wish to get stranded on a freeway!

Re: 82 green oxidation on radiator (Skyhigh82)
Probably still ought to replace it. It's 20+ years old now. Unless it has had excellent care it is probably wearing thin and will leak soon. You could clean it and see what it does on the outside, but it is probably clogged and nasty on the inside. You could have it re-cored for that $175 or so or get a nice Aluminum replacement from DeWitts for a bit more. You would have way more heat rejection capacity and they look neat too.

Re: 82 green oxidation on radiator (markdtn)
That is good advice. Despite my comment re the 24-year-old rad still doing well I would have it recored before next summer. Mr. DeWitt gives you other options if you wish to go up-scale.

You might be able to rent it at autozone, Murrays, or any u rent um. the pressure tester is expensive to buy, or you can drive to a radiator shop and they will pressure test the rad for you

That tool is kind of expensive, but after having one it is hard to do without. You can pump up the pressure with the car cold and find loose radiator hoses, loose t-stat housings, marginal water-pump seals, etc. You would be amazed at how many cars losing water can be attributed to loose radiator or heater hoses-also radiator caps. Of course, it will also pressurize the radiator and that is what you are looking for here. It fits most American cars from mid-80s back and adapters can be bought for later American also Japaneese and German cars with different necks.
