Hi all,
I lifted the bonnet today and noticed this white chalky crust all along the coolant pipes near the reservoir. Has anybody had this before? The van has never overheated and I've not noticed any coolant loss. I've also not heard any stuck pressure hiss out from the reservoir when opening it. Any ideas?
