Just want to make owners aware that basically ALL new vehicles have air in the cooling system when delivered; it's perfectly normal. So it's really important you watch your coolant reservoir(s) at the beginning, and top them off until system is stabilized, which takes dozens of cold-hot-cold cycles. The worst vehicle was my ex-Porsche, since the engine is at the rear, so lots more air in the system than a front-engine vehicle. Anyway, in most of my vehicles, when I check the coolant reservoir after a week or so from delivery, the level is at or near the 'min' line. Once I top it off, it never goes that low again, but still have to top it off like maybe twice more. Oh, and I always buy a bottle of coolant at the dealer when I buy a new vehicle, but watch out if it's not 50/50, meaning you have to dilute it 50/50 with distilled water. Hope this helps.
