Let me preface this question by stating that I am uninformed when it comes to not only this specific cooling system, but also regarding closed systems. Okay,
It is my basic understanding from reading this thread that the only access to the cooling system here is the overflow bottle. If the overflow bottle is at the rear of the engine, then parking downhill would allow the cooling system to purge out the air, due to the air flowing out of the bottle at the back, correct?
I saw somebody post about a place in the front of the engine where air and coolant would exit. How/ why would coolant leave the system? Leaks are no bueno. If they were simply referring to the fact that it flows to the radiator in the front, then how would this alleviate the issue of trapped air?
Just trying to use logic here, thanks for the expertise you all have/ will show.

Beast, check the coolant reservoir for cracks, there should be no coolant coming from the reservoir. If the reservoir is in good shape, take the cap off (when it's cool) then start the engine and let it run for a few minutes, that should cycle any air bubbles out of the system. Make sure your heater is ON full hot when you do this so that you get any air pockets in the heater core as well. Then report back. If that doesn't fix it then we'll move on to the next step(s).

The kind you bought is a cheapo and doesn't seal well generally. The threads don't hold on to the bottle well. The 703-1396 is a Volvo cap and holds a higher pressure, holds the threads better and offers more underhood clearance. I don't think the cap is your real problem but that chinese POS will fail in short order.
