I'm new here so let me just give you a word about me and my car(s)! I inherited a restaured Datsun 100A and multiple dead ones ready to build a running one from my dad. We worked together sometimes but he did the shopping and I just helped him in the garage. Unfortunately he has passed away recently and I'm now the proud owner of the cars (well, together with my brother).
We just wanted to get the running one ready for the street and there is some coolant missing. What do you recommend me to refill the coolant? Distilled Water or do I need some special coolant?
Thanks for your suggestions ;-)
P.S.: Here some pictures of the beauty in the open field:
