The engine is STILL putting off the same amount of heat as with a 180 tstat so steady state will inevitably be the same, but with the 160 tstat it will take longer to see the steady state, and depending on the drive/weather, you may no longer get to steady state of ~195 on the freeway and 204ish while sitting still.
You'd be amazed at the number of people who "don't get it" LOL You'd think they owned/drove air cooled cars their whole life

The coolant capacity went up on the 3.2 cars only. They have MUCH bigger water lines than the 2.5 and 2.7 cars, plus the 3rd radiator.

Technically, as displacement goes up on these blocks, there is actually LESS coolant in the block (the cylinder bore gets bigger) The 2.5 and 2.7 share the same bore size
