Coolant overflow tank

[Rodd]

My coolant overflow tank is leaking. I got a dorman branded one from O'Reily and it has a press on and pull off lid. The one in my truck has a radiator cap and is under pressure. Will this work or do I need one that has the radiator cap?

you need one with a radiator cap.

Yes, ours isn't an overflow like old green antifreeze tanks it's more an expansion tank needs to hold 15-16 psi iirc.
