While checking the OEM specs on the Aeroquip push-on type hose I noticed something interesting. The max operating temp for water is 180 F.  250F for other fluids. So I guess no one is using this for the radiators..right?

I sure didn't see that little restriction.  On the single rotor, I've use this hose for all the coolant lines, but as Ken mentioned, perhaps that's OK, as it becomes "other fluids".
