Radiator identification

Yes I agree about the overflow after traffic. It's just that I noticed some seepage down low and lower tank paint washed off, indicative of a small leak. Not sure if the inside is clogged.
I'll just take it out and maybe bring it to a shop and have them give it the once over. Ill be sure to keep the same rad...Thanks for the Intel on the green. I'm old school w lubricants that way. I'm not a synthetic oil guy either.
Anyways I feel better and thanks for reaching out.
