Okay update: Still haven't bled the system. Just been very busy, so will definitely do it tomorrow.
Coolant is still leaking, and I was wrong, my passenger footwell is not actually wet. I imagined it was wet because there was a dark patch but it was just probably dirt or something. It definitely is not wet. I am loosing quite a bit of coolant each time I take her for a spin. Weird thing is, it always drops to this specific point, leaving me with about 1/4 or less of water in my tank. Fill it back up to middle of the coolant tank, and check again after a run and its gone back down again.
I understand that there was a coolant cap recall? How do I tell my car has got the updated cap?
Finally any ideas would be helpful..
many thanks.
