How do I check the timing? This car has a timing chain.
No I bought it from a guy on CL. I took it for a 45 min drive the first day I went and looked at it, and it never overheated. Where I bought it from it's generally flat terrain everywhere. Considering it has to be going uphill to get stressed enough to overheat, I'm not really inclined to think he knew, but then again, who knows.
The car has a major exhaust leak where the pipe connects to the cat, it sounds like it's unrestricted.

If you are EVER getting air bubbles out of you coolant, you need to continue to bleed the system. ANY air left can create an overheating issue. Your cooling system operates under pressure to avoid boiling the coolant, if there is a slug of air or "micro bubbles" it will compress and lower the pressure in the system which will cause your coolant to boil.
As old mech has stated, if all the air has been removed, those "micro bubbles" are coming from a blown headgasket.
If you are sure its not the head gasket, inspect all coolant hoses and verify there are no leaks and the hose clamps are tight.
Bottom line is, air is getting in and causing your car to overheat. Find out where.
