I have a leak on my GTP at the fitting that's on the lower right side of the radiator. How the heck do I take this nut off? What do I need to replace this fitting

[l67ss]

18mm flarw wrench

[jc71corvette2]

For that outer nut

[l67ss]

Yup and once you have it loose u can use a pick to remove the clip

[jc71corvette2]

Ok. And would a gm quick diconnect tool work

[l67ss]

Only if its for tranny lines. Fuel quick connects are totally different
