It’s a 10 mm it’s been a few months since I had mine out to rinse and inspect for cracks when I changed my Dexcool, I’m pretty sure it’s a 10 mm

I update and correct this information for future readers

So M6 would have a 10 mm head.

I went out to my HHR popped open the hood and visually inspected the bolt, it is definitely a 10 mm
