How much coolant

[FeelDatPowerstroke]

I have a 94 F-250 powerstroke 7.3 with air conditioner how much coolant does the radiator hold non diluted

[backwoodsboy]

4 gallons.
Add four gallons of concentrate, then add distilled water until full. No chance of having water remaining in the coolant passages diluting your mixture this way.

Radiator only holds about 4 gallons.
