Over the past month, my heat has slowly stopped working. Why? Because there was air in my lines. When I was stopped, the heat would get cold...and when I took off, it would warm up. So I bled the system and got two great results (one on accident).
1. My heat now blows fire
Before I continue, let me add something: For a long time after my car overheated a few months ago, it would shake (vibrate) really hard at speeds above 60 mph, I didn't know why. So...
2. Now that the air is out of the lines, the car doesn't shake anymore and I'm a happy guy. I had no clue air in the lines could do that. I hope I didnt' break anything.
