The A/C does not contain Freon. Contains R-134. If you are having to add refrigerant, it means you have a leak. It is illegal to add without first fixing the leak. Special tools are required to repair and add refrigerant. Take it to an A/C specialist.
The system has 2 valves, like car tires. The recharge can(s) have a fitting for these and probably a gauge. One will be on high side and one on low.
No, no room.
The only place available is the coolant reservoir.
Aprox 30 oz.
Either the thermostat was not the problem, or you put it in backwards.
To disable the factory alarm on a 2000 Mercury Villager, put the key in the ignition and turn it halfway. Let it stay in the spot for 10 minutes and start the car.
Nothing. The Villager can run any normal ethanol-oxygenated gas up to 15% with no problem.
Under the hood of the 1996 with the F22 4 cylinder engine. It states 22oz of freon.
Down same tube that holds trans dipstick.
NO , your vehicle is designed to run on " regular " unleaded , 87 octane
Number one rule with refrigerant is, "If you have to add it, you have a leak." Auto refrigerant is sold in pressurized cans and, to my knowledge, requires certification to purchase and use. There will be a port with a cap on the line coming out of the top of the compressor. Screwing the can on will fill it, but overcharging will reduce the cooling power of the refrigerant. You can buy it at any auto store. Even Walmart carries it. No need for a cert.
The same place where you check it, there is a tube that comes up in the right center behind and to the left of the coolant reservoir. It has a small black ball on top. That is your transmission fluid dipstick. It is, unfortunately, not marked in any way. Pull that out and if you need to add fluid put a funnel in that tube and do so.
