You are best to use a semi-synthetic oil. Preferably 10W40.
There isn't one, you have to remove the pan to drain the fluid.
it may be one of the engines that dont have a drain plug exactly if it has a big plug on the bottom of the oil pan that the oil filter is in you drain it when you pull the filter (if the filter is built into the big plug on the bottom of the oil pan)
It may or may not have a drain plug for the radiator. Look at the bottom of the radiator usually on the passenger side of the car. It doesn't really look like an actual plug. It is more like a plastick wing nut, just unscrew it and it should drain. Some radiators don't have drain plugs at all. If it doesn't just take off the lower radiator hose from either the radiator or the engine block and do it that way i think the sunfire drain is on the driverside of radiator facing forward. it should be a 1/4 inch hole in center. you have to turn and pull to drain. be careful not to damage plug or radiator.
Oil drain plug is just to the right side of the oil pan from the filter. Heads up, it is pointed sideways so when the plug is removed oil squirts waaaaay out there. Good luck catching all of it.
