Just wondering if this is something to worry about. Seems like there is some minor corrosion at the lower corner of the inner radiator core. Not sure if it is because there is a leak (unlikely, since I have been monitoring the coolant level over the years, and it barely goes down at all) or is it just from driving in the mid-western winter with all the salts on the road.

Spray clr and wash it and look back at it in a week or so to see if it's on the same spot but you would know if you had a leak most likely salt from your roads

My car has seen a lot of salt. I don't have that on my radiator. It could be a leak. On one of my trucks I had a similar issue. Microscopic hole that sprays steam only when the coolant get hot hot. Having the residue only on one corner is suspicious.
Please set us know how it works out.

The picture is showing a corrosion leak. Today, I replaced my radiator and it looked just like that. It started leaking a little, and I put in a new one. the old one looks like the picture.

Is that the CSF radiator or your stock one?
