That depends on what model year of Ford Explorer :
My 1995 holds ( 79.5 litres / 21 U.S. gallons )
I believe the 2002 and newer models hold ( 85.2 litres / 22.5 galons )
22.5 gallons ( 85 liters )
85 liters, 22.5 gallons Siamand
In a 2003 Ford Explorer : The gas tank size is ( 85.2 liters ) if that is what you are asking
I believe it is 17.5 U.S. gallons ( 66.2 liters ) on a 2 door Explorer
22.5 U.S. gallons ( 85 liters ) - Helpfull
about 21 gallons ( 79.5 liters ) for the 4 door and about 17.5 gallons ( 66.2 liters ) for the 2 door
The 4 door holds 21 U.S. gallons ( 79.5 liters )
21 gallons ( 79.5 liters ) - 4 door 17.5 gallons ( 66.2 liters ) - 2 door
It should be the same as my 1995 - 21 gallons (79.5 liters )
You can use about 5 liters of oil for your Ford explorer 1997.
22.5 gallons / 85 liters on a 2003 Ford Explorer 4 door
