Question after doing coolant flush and fill...
I just flushed the evil DexCool from my '98 LeSabre, replacing it with Prestone Extended Life (DexCool Approved, reddish color). I also replaced the 195 degree stock thermostat with a drilled 180 degree Stant, with a new o-ring and gasket.
I followed the directions for bleeding out air in Techinfo as well as possible, but I do have a question...
I know the thermostat is opening properly, because warm coolant does flow through the upper radiator hose once it gets up to temperature. But, how "firm" should the upper hose get?
Mine is easily squeezable...not a damaged hose, just that it feels like it'* half full of fluid and half full of air.
Is that normal? I would have expected more firmness.
