Very carefully!!!!! If you dont have a lift you are at a disadvantage, you must find the drain plug located at the lower tank of the radiator perhaps near the cooler lines side? before draining it use a bit of baking soda to neutralize the rust etc. in the sytem after you run the engine for a few minutes let it sit get cold then drain from the drain plug remove the radiator cap to allow air into the system so it drains faster, check with the dealer on what type of anti freeze they recommend and go by there direction, Check all the hoses and belts at this time and also may be a good idea to replace the thermostat and gasket too. Mix the anti freeze as recommended and add until system is purged of air and full.

Most likely.
Take the cap off the radiator and open the petcock on the bottom of the radiator.
The radiator drain plug should be located on the bottom of the radiator on the passenger side. Open that, let the old coolant flow into a drain pan, replace the drain plug once the coolant is out and the radiator is flushed, then fill it up through the radiator cap.
It doesn't have a drain plug. You either have to pull out of the fill hole with a vaccuum devise , or take the cover of to drain.

Even without a cap, you still have a drain plug at the bottom of the radiator, it will unscrew, and release all your water, then you have a separate resovoir for coolant that you fill it back up with, it will say coolant on it.
Low of coolant or overheating.
The heater uses the engine coolant to heat the vehicle. The radiator has a drain petcock along the bottom edge to drain the coolant system.
