Hi, I have a 64 plate MK7 VW Golf, 1.6 TDI. I recently put some G30 coolant in as it was running low, the recommended coolant is G13. Will this cause any issues?

Thanks.

It's pink and blue coolants you shouldn't mix, in VWs at least. It used to congeal into water way blocking clumps.

Coolant is a real mine field with contradictory information all over the place.

Prestone claims their coolant mixes with anything and I’ve not heard of anyone having any issues.

More specifically, G11 (blue) couldn't be mixed with G12 (pink). Not sure if the G11 equivalent stuff is still around.

With G11 G12 G12+ G12++ and now G13 it’s easy to get confused. G13 is purple. If it’s not reacted in the header tank you are ok.
