Since the first model year of the Mercury Mountaineer is the 1997 model it would be ( r134a )
rings or seals
That would be the 4.6 liter engine, which takes six quarts. * of 5W-20 according to the 2003 Mercury Mountaineer Owner Guide
An ABS fault.

On a 1997 Mercury Mountaineer : I assume the fuel filter would be in the same location as a 1997 Ford Explorer : ( underneath the Mountaineer , below the drivers door , mounted on the frame rail )
the blend door actuater is bad
bearning on front breaks burn out
you would have to see a mechanic about that problem
I assume the 2002 Mercury Mountaineer would be the same as a 2002 Ford Explorer ( No , starting with the 2002 model there is no automatic transmission fluid level dipstick ) Ford has a way of checking from underneath the vehicle
Bank 1 is the passenger side of the engine in your Mercury Mountaineer Sensor 1 would be close to the engine before the exhaust enters the catalytic converter ( upstream sensor )
