Just picked up this subaru used and I have been doing more and more maintenance when I have the time. I popped the coolant reservoir cap and it looked like syrup. So I decided to flush since I have taken care of all the other fluids.
So I flush the coolant out, get new coolant in it and the temperature was doing some weird fluctuating but it was come and go. So I popped the cap again and the coolant looked just as bad before so I decided to flush it again and see if maybe there was air in it.
After I got all the old coolant out it made the problem worse, this time the car constantly wanted to overheat. When the coolant temp started to get close to the red, the heater started blowing cold. As soon as I start decelerating I can see the temp gauge go down and once I come to a stop it drops down to a normal temp almost instantly.
Did some reading, I saw others with this problem and it seemed to be the thermostat. I replaced the thermostat and the radiator cap and it has made absolutely no difference. I thought it was fixed, but when I was driving home earlier I realized the heater was blowing cold and it was nearly in the red again.
I bled the system for 30 min, but it seems like the issue is an air bubble in the system. Any idea how I can get rid of it, or does anyone know what my problem might be?
