Default Radiator drain petcock location?

Any idea where the drain is located? I have to get under there this weekend. Took a quick glance at it this afternoon and did not see one. Thanks!

If I recall, its on the lower left side and is a recessed plastic cap about the size of a half dollar. Don't expect to find an old school brass spigot sticking out

If it's an 03 it's on the driver's side bottom corner of the radiator. If it's newer than an 03, it doesn't have one. Just pull the lower hose off or something to drain it.

2003, look through the drivers side wheel well at the body mount and just to the right of that is the drain. See pics.
