If you're looking to replace the petcock, self service salvage yard or auto parts store. The plastic ones just pull straight out (with pliers) and the new one pushes straight in (by hand). O-ring press fit. 19mm (3/4") socket or wrench loosens the white plastic nut to drain coolant. Wheel lug wrench, crescent or pliers will also work. Always retighten the nut by hand or risk breaking it off. Then, you'll have to use a 3/8" allen wrench to open/close the petcock, lol. Petcock is located on the bottom drivers side of the radiator under the black plastic air dam.
