[Havent't been on here in a while, and nothing obvious pops up on a couple of searches] After getting the coolant-swap a while ago, I've noticed that the level in the reservoir has dropped slightly below the "min" mark. Does anyone know enough about the composition and specs of the hyper-expensive Hyundai blue stuff to comment on whether simply topping up the level with a little deionized water is a bad idea? It wouldn't be nearly enough to affect the antifreeze ability of a typical 50/50 mix. _H*
All I can offer is that a slight drop in coolant level has frequently been reported after the coolant swap procedure. Owners drop by the dealer and they top it off for free.
I'll go the water route as an experiment, then. I also haven't pulled out my coolant testing stuff in a while, it'll be interesting to see how the strips react to this variant. _H*
