I hope this is one of those "easy if you know the answer" type questions, long story short - I had to replace housing from a coolant leak, I had called in to Halfords to purchase coolant prior to this to top up, my confidence in the salesguy was low, when I gave my reg (2013 C250 CDi B.E.) he gave me this:
Halfords OAT Ready Mixed Antifreeze 2 Litres
What struck me was that it was red/pink - but before my previous coolant tank emptied I remembered it was blue - AG13 Antifreeze (Hightec)
Does the red/blue mean anything or simply the different manufacturers trying to mess with our heads? I vaguely understand the OAT reference for newer engines but would it do any lasting harm to my OM651?
