how does the difference between a 160,180, and 195 degee thermostat effect engine cooling and heat in the cab in the winter. this is on a 1968 ford f100 pickup with a 390cu in engine. i just bought this old truck and it does not seem to get very warm in the cab. the heater control valve is new and the radiator is full of coolant.

You have a stuck thermostat, or at least one that is partially opening. Stuck shut and the vehicle overheats, stuck open and the engine runs cooler that it should and the heater doesn't get very warm, if at all.
A normal thermostat should open and close to moderate waterflow and keep the engine at the correct operating temperature. Each engine requires a different heat range. Go to your local auto parts house and they can get you the correct one.

The temperature at which the thermostat opens and allows the water to circulate. For that engine you'd need a 180.

That is the temperature that it opens up and allows water to flow to the radiator to cool your engine. This valve can be stuck open slowing or limiting the engine heat. Take it out when the engine is cool and put into a pot of water then boil the water. It should open at the specified temperature. If it is open when you remove it (air blows through it), then replace it.
Use the right one, you can kill your mileage if your engine is too cool and cause nitrous oxide emissions and excess wear if it is too hot.

The hotter your engine is the hotter the heater is.
