Question about 2005 Pontiac Sunfire
Where is the radiator cap and drain plug in a 2005 Sunfire? I want to do a radiator flush.
Radiator cap would where theradiator is! and the drain plug at the bottom. Make sure you add anti freeze if required in your area.

The textbook method is to remove the drain plug on the bottom of the radiator.
Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.
The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.
Drain the coolant onto a large drain pan and recycle the coolant
I just did a FREE write up on air purge from coolant system and how to detect initial state of blown head gasket at the Fixya tip selection.

the easiest way that I've found is to just remove the upper, and lower radiator hoses from the engine. point the hoses downward, and spray thru the top hose with a garden hose, also spray down the radiator cap inlet. If the cap is crusty replace it, I also recommend removing the overflow and washing it out if needed. and yes the drain plug is hard to get to, plastic that likes to snap, and not worth messing with
