My apologies. As I said, I am no expert

When I saw coolant spewing from my car, I referred to it as "leaking (bubbling explosively)". But I guess that was a poor choice of wording.
As far as I can tell, it is NOT leaking from any hose, plug, orifice, etc. The only place that I have seen it come out of is from the overflow cap, which I assume (based on other posts) is due to the overheating.
I have had the car since November, but only driven it a few weeks before having it garaged all winter. I had driven it a few times before this thread (after winter), with no problems and only recently have had this problem. My first post in this thread was the first time that it has overheated (for me- I can't speculate as to the previous owner).
I haven't driven it since then, except for today when I brought it to Midas.
I have not bled the system, but I found a good tutorial so I think I will toy around this weekend.
I hope that helps!
