G12 Coolant question
I don’t know if anyone else has had this issue but it’s worth a shot. My coolant light came on yesterday and I called my local VW dealership to see what I needed (lost owners manual somehow?). They said it would be G12 but I was wondering if different brands can be mixed together as I have no idea what is in the coolant reservoir currently. I got my head gasket replaced last year and I assume the dealership put back in whatever they had which was probably VW/Audi brand. Would it be safe to mix coolants as long as they are both G12 and the same color? I don’t want it to turn to sludge and ruin my radiator LOL.
