Plug for radiator....removing oil cooler lines.

Looking for the plugs used when you remove the cooler lines on the radiator....thanks in advance.

Just use those red and blue plastic ones that come with a new radiator....... LOL.

Mine are standard threaded, hex drive, screw in plugs with some teflon tape.

Sorry, shoulda read your question more closely before firing off my answer Rick!
I see you mean the oil cooler lines….Duhhh
Not sure about the threads in radiator , but the lines are 5/16” inverted flare

Mine are NPT, not standard, sorry.

The radiator takes a 1/2 tube nut that is 3/4 -18.......I bought the nut and plan on pluming it and welding it shut. I could not find a plug but one must be out there. This is for a stock radiator.
