A ticking noise from the engine bay, an exhaust smell or a visible crack in the manifold can mean it is leaking. These signs alone do not prove the manifold is at fault, since a loose downpipe joint can sound similar.
Fits
This manifold also fits the 2018-2020 Ford Expedition V6 3.5L and the 2017-2020 Ford Lobo V6 3.5L. It is made to fit and work like the original manifold on these vehicles.
