According to the 1997 Ford Explorer Owner Guide :
With engine oil filter change :
The 5.0 liter V8 engine takes ( 4.7 liters / 5.0 U.S. quarts of 5W-30 )
5.0 US QUARTS
22 ozs
The maximum towing capacity of the 1993 Eddie Bauer Edition Ford Explorer is 5,200 pounds. This is for a 4.0 Liter V6 engine.
For a 1997 Ford Explorer 4.0 liter V6 engine ( EFI and SOHC versions ) ( There are 6 spark plugs )
According to my Haynes repair manual, 1997 through 2000 Ford Explorer models: have a R-134a capacity of 22 ounces
My 1995 Ford Explorer 4.0 liter OHV engine is rated at 160 horsepower , the 1997 4.0 liter SOHC is rated at 205 horsepower , the 4.0 liter SOHC is currently rated at 210 horsepower
According to the 1996 Ford Explorer owners manual : The cooling system capacity for the 4.0 L - V6 - with air conditioning is : 8.6 U.S. quarts / 8.1 liters
about 5 qts
The 1997 Ford Explorer available V8 engine is a 5.0 L (302 cubic inch) The oil filter is on the driver's side of the engine, towards the front.
5 quarts ( 4.7 liters ) with filter change
15.7 quarts ( 14.9 liters )
I would assume the 1997 Ford Explorer is heavier than the 1998 Ford Crown Victoria ( especially if the Explorer is 4X4 or AWD or has the 5.0 liter V8 )
