A central air conditioner should be set to a temperature that is comfortable for you, usually between 72-78 degrees Fahrenheit. Setting it lower than necessary will not cool your home faster and can lead to wasted energy and higher bills. It is recommended to aim for the highest temperature that is comfortable for you to save energy and money.
yes, by using less air-cond

It could just mean that the AC has leaked out all of the refrigerant.

Here are the specs I have for 1987 Ford Ranger engine coolant capacities (50/50 mixture): 2.0L Eng: 6.5 QTS. 2.3L Eng,Diesel w/Air Cond: 13 QTS. 2.3L Eng,Diesel w/o Air Cond: 12 QTS. 2.3L Eng,Gas w/o Air Cond: 6.5 QTS. 2.3L Eng,Gas w/Air Cond: 7.2 QTS. 2.9L Eng w/o Air Cond: 7.2 QTS. 2.9L Eng w/Air Cond: 7.8 QTS. Hope this helps! -- Rick

Yes
Defective actuator behind glove box that controls air flow.
is recommended if air cond. doesn't work
No, it contains too much moisture.
If the engine coolant is not circulating then there will bee no heat, and the temp sensor may or may not read hot. Make sure that the new thermostat is working and not installed upside down, as this is easy to do.
