Radiator fluid question
I'm fairly new to the model A world and I have a question that has probably been answered many times before.
I recently bought a '31 coupe and I've been doing routine maintenace on it. I'm getting ready to drain the radiator and I was looking for guidence on what I should put back into it. Straight water or a mix of water and antifreeze? How many total gallons of fluid go back into the radiator?
I live in MN so yes the cold winter weather is approaching. I don't know what's in it now and I want to make sure I drain it incase it's straight water. I don't want the block to crack during the winter.
Advice on this is greatly appreciated.
Thanks!
