How much coolant does a ford ranger hold?

The amount of coolant Your Ford Ranger will hold varies wildly depending on engine size and model year. The typical range is between 1.2 and 3.5 gallons, though it's possible that some larger engines will require more. It's really best to look up the factory specifications for Your particular Ranger model year and configuration, since it's asking for trouble to drive with too little coolant. Conversely, adding too much coolant can be a bit of a grey area as well. If You're in doubt, You can always use the fill line specified under Your hood; it may not be a perfect indicator of particular amounts, but You'll be in a much better range. Sorry I couldn't offer more specifics, but You didn't give us much to go on.
