New Radiator

[Apewrench]

i ordered an aluminum from autocity as well.  Just wondering what coolant did you run in yours?  TIA

I have a different setup but is aluminum as well.
Hands down this has been the best Coolant I have used. I have multiple classics.
Every other has shown to start the corrosion process from electrolysis quickly.
Nothing ever with this brand.
I purchase thru Tractor Supply.
