2006 LX w/143k babied So Cal miles, second owner since 2009. In the middle of doing a coolant system cleaning and in a few days I'll finish with repeated cleansing flushings with distilled, then new SLLC.
Using ThermoCure, it's in the system right now, driven 1-1.5 hrs daily the past few days, and burping in between, and the front heaters are back to cranking out tons of heat, which was missing before this process.
However, the rear heater vents (under front seats and center console base), while getting warm, don't crank out really hot air. Everything for the rear heat is on correctly.
Suggestions? Maybe still some air pockets or sediment? Or does the rear heater just not crank out the heat like the front?
