appreciate any advice--local mechanic performed coolant flush / changed thermostat. Now truck doesn't get heat, and doesn't cool correctly...keep burping the system but the upper hose has bubbles and losing coolant somewhere--no leak, and oil looks clean. Used OEM premixed Mopar purple, which looks same as what's in it. Changed out the thermostat again, no difference--other than engine temps running way high especially considering it's 10 degrees outside. There were no cooling issues before. 2018 5.7 117k miles.
