    You should do what the owner's manual recommends.

    oil cools the engine and freon (?) cools the passenger space, so Im not sure which coolant were talking about.

    Read the owner's manual: there should be a chart for normal and severe driving: decide which applies to you and follow that.

    what type of coolant , ordinary or long life , it depends on what the coolant maker says , not your car maker . read the label on the bottle .

    If you have DexCool antifreeze I'd change it every 30,000 miles or 3 years because it tends to plug up heater cores and radiators. The green antifreeze gets acidic over time. I change green antifreeze every 60,000 miles or every 4 years.

    It's usually done on a time basis, but if your manufacturer recommends a mileage then go by that. A good coolant contains not only antifreeze but also a corrosion inhibitor and a little something to help lubricate the water pump.  These lose their protective properties over time. Personally I change ours every few years no matter what the mileage.

    The coolant should be CHECKED far more often than that. It should be replaced based on condition, not miles.

    You should follow the manufacturer's recommendation;  on my cars that is based on time, not miles . . . since I don't put many miles on its not uncommon to have coolant changed at 3 years with only 15,000 miles . . . . . coolant doesn't lose it's ability to prevent freezing but does lose anti-rust and lubricant protections.

    After 14 years, YES, change it with ATF.
