The hoses are factory from 2000. I can squeeze the hoses easily there are no springs in either of them. Fluid levels are fine. I have a mezeire ewp, and 160* thermostat that is about ~5 months old. The car has always run a little hot for my setup at about 190*-200*. still on stock tune for fans.
I run 50/50 dexcool mix. I used to add water wetter, but never noticed a difference, so stopped like 2 flushes ago.
Just a side thought, but I think the lower hose has vacuum and the upper is pressurized under operation.
