Where is the petcock valve located on the radiator on 1993 toyota camry V6?

Hi,
There are no petcock valve on toyota camry.
What its a plain radiator cap that has a valve in it, pressure can be activated at certain point and the coolant goes through the coolant reservoir.
You mean the radiator drain plug? you would see that plug underneathe that radiator assembly, wing nut type plastic made, can be loosen by hand or a pair of pliers!
Hope that was your looking for!
Thanks for using Fixya!
