got the temp gauge to start staying a lot steadier and not pegging out when it really wasnt 260+ degrees. i had some air in the system, and now that i got it out, the upper hose stays VERY pressurized while hot.
much better than before.
but,
every now and then i will hear this hissing type sound coming from where the heater core is located.
my floorboard isnt wet and i cant find a leak anywhere around there, but i'm sure it has something to do with the heater core.
