i added about 1/2 gallon or water to my coolant today, do i drain and add all anti free b4 the winter hits?

 

you usually don't need to change your coolant for a long time, i think 30-45k.

but if you get prestone kind of coolant, you are suppose to do a mixture of 50 water to 50 antifreeze.

i got antifreeze from honda and it states that it does not need to be mixed with water.
