If you drained the pan it will be 5-6 quarts.
The Mercury Villager is a badge-engineered Nissan Quest. The vehicles are mechanically identical.
Yes, the 1993 Mercury Villager was a 1992 Nissan Quest. The last year Nissan used a Carburetor on a Quest. Fuel injection system replaced the carburetor in 1993.
1999-2002 Villager or Nissan Quest.
Yes, they should be identical.
The Nissan Quest starter is the same.
under the hood
Located diretly behind the center console and it is a real pain to get to. Try buying the Haynes manual for the Mercury Villager/Nissan Quest and it helps somewhat.
97 Villager uses timing belt on their 3.0 engine same as Nissan Quest.
I would suggest you get a Haynes repair manual. Number is 64200. It is the same as a Mercury Villager.
On my '93 Mercury Villager is a T40 Torx it should be the same on your '96 Quest.
The "flex plate" will interchange as long as the donor vehicle is the same year and has the same size engine. Both vehicles use Nissan powertrain.
I believe if you research the issue you will find that the Mercury Villager is actually a Nissan Quest and I doubt that the engine will fit the Ford Ranger. Good Luck!
