I checked coolant and it marked 12c on the gauge I think i need to change can't find a valve but by the freeze plug there is a hexs can that be a drain? And can I use regular car antifreeze?

It came with propylene-glychol anti-freeze from factory. It is not a good idea to mix with the more common ethylene-glychol. Both work fine but you need to flush radiator and engine before changint to different type of anti-freeze. The additives of the 2 types tend to react against each other, forming a sludge that can plug coolant passages in the engine & head gasket.
