I have just purchased a pre-owned 2015 Transit Connect. Very happy with it so far except I find that I can top up with coolant and after a few days of driving it has dropped below the minimum level despite the van not overheating. I took it into Ford and they did a pressure test and confirmed no leaks in hoses etc. as the pressure test indicator didn't move.
Has anyone experienced the same thing or have any insight to the problem as I can't see it right having to top up water so frequently.
