Only has one and that is in the radiator, but it’s been my experience that you do not loosen it up to drain the radiator as it usually breaks or the ring goes bad and it won’t seal afterwards, work best to remove the lower hose and drain it that way, yes it is messy.

They have replaced the drain plugs with Knock Sensors. Remove the Knock sensors to drain the block. Radiator may not have a drain cock.
