Re: 4.0L vs 4.2L Manifold

In respect to the question about the manifold, I know that putting a 4.0 where a 2.5 used to be is a common swap. Has anyone done this swap, How did the cooling system work out. Did you have problem with overheating with the larger motor. Does anyone know, or have any thoughts?

91 YJ swaped in 4.0L 2 inch lift. (work in progress)
