A 97 Mercury Villager should use r134a type freon. The valve size is designed so that the r12 fittings cant accidentally be used.
R134
1994 Mercury villagers come factory charged with R134a refrigerant. Vehicles built 1993 or prior were charged with R12 for note.
A 1998 Mercury would use R134a refrigerant.
5W-30 is the preferred oil ( according to the 1996 Mercury Villager Owner Guide )
The Villager does not use fusible links that I am aware.
To recharge the air conditioner in a 1999 Mercury Villager, first, locate the low-pressure service port, usually found on the larger diameter line. Use a refrigerant recharge kit, attaching the hose to the port, and follow the instructions on the refrigerant can. Start the engine and turn the A/C to the maximum setting while adding refrigerant until the system reaches the recommended pressure. Monitor the pressure gauge and avoid overcharging, as this can damage the A/C system.
To change the air conditioning (A/C) on a 2001 Mercury Villager, you typically need to access the A/C system components under the hood. This includes locating the A/C compressor, which is driven by the engine belt, and checking the refrigerant levels. If you're looking to recharge the A/C, you'll need to use a refrigerant recharge kit to add refrigerant through the low-pressure service port. For more extensive repairs, it may be best to consult a professional mechanic.
The Villager has an electric fan and does not use a "fan belt".
