Can you over fill the coolant in a 1979 MCI bus?
I topped our little super Betty's coolant off today, and filled her to the top of the filler cap, then thought about it and thought maybe I shouldn't have done that. Maybe I should have thought first?
As long as you can touch the coolant with your finger, you are in good shape. Coolant expands and contracts with the temperature, what ever you've put in that gets spit out was to much.
