Niro HEV Coolant for Engines

In between services, I occasionally need to add as much as 200 ml of coolant, just like I did with my previous vehicles. It appears to be under normal use; I have not detected any indication of a leak.

The pink coolant used has the KIA part number 66927 ADEP0. Would you rather use this brand or one from a third party?

Text from the manual: -

So not very picky?

Why take the chance of a mixing disaster just to save ten pounds when it already contains kia coolant? A bottle will last you five years if you only top it up with 200ml.

It took 200 ml to fill it to capacity, but I haven't needed to refill in over two years.

Or for those of us who are finicky. forty pence for distilled water from halfords. Only a few millilitres will be ineffective.
