2003 Mazda MPV ES
Developed a radiator leak on the lower passenger side attempted to look didn't see any cracks on the plastic . Antifreeze is dripping even when vehicle is not running. Checked upper and lower radiator hoses and they appear good.
Could it be leaking from the petcock? (Does it have one)

Thank you so much for your help.


those are plastic crappers, often leaking at the seam where the plastic and the aluminum are press fitted together. Just change it with a cheap aftermarket rad, they work fine
