Heater Temperature? Core Blocked
Ok so there is alot of information about this out there! I had the issue with my heater sucked! My AC works great and as far as I could tell everything else in the system worked fine. I got cold air, then when I switched to hot, I received a brief glimpse of hot air. I went ahead and flushed out the heater core using a hose, got all kinds of brown crap out of there. And the flow of clear water was great before I finished up. And the heater worked great. I did the flush probably 3 times before I got good at it and was able to get noticeable effects. I put a thermometer in my vent and was able to read about 120°and the factory service manual declares 120° from your vent as proper operation. I didn't like this, my Dodge blows out air so hot that I cannot bear it for very long; it burns me. So a month or two goes by and one night my heater seems to be not working effectively, it got cold at idle. So I blasted that thing out again with the hose. Again I saw brown crap come out. This all makes me wonder if my heater core has such an issue, why not my radiator? But the system runs super cool all the time! So I tested my heater again, and this time it's blowing like it's from Hell! I temped and was reading 137.7°and I felt the heat! I mean this thing is hot now! I just wonder what everyone else is reading out there for their heater temperatures. Oh and I should mention I changed the thermostat out right away, since that is the standard fix for this issue. But in this vehicle, coolant is always running to the heater core, and I don't think the thermostat would make a difference in this issue. Anyone else out there temp their heater?
