    Yesterday i drained the engine coolant on our Auris Touring Sports. I was wondering what type this is.
    Is it the long-life red one, or the super long-life pink one that is just dirty?

    The car has 100k miles on it. I couldn't find anything in the maintenance history so this was probably the first time it got changed.

    On the left the fresh new pink SLLC one, on the right a bit of what i drained:

    The full amount of what i drained


    I drained using the small tap at the bottom of the radiator. I got about 5L / 5.39qts / 1.35gal in total, i thought i would get some more (6-7L) but nothing more came out of the radiator.
    I don't mind though, as the SLLC stuff is quite expensive in Europe (i paid €7,53/1L or $8,95/1qt) and cheaper alternatives like 'Zerex Asian' aren't available in Europe.

    Probably the concentrate vs the premix. Or could be the aftermarket Asian. I would not worry about it.

    The best strategy might require multiple fills, warm ups and drains with distilled water and then use the concentrate figuring in a gallon of the distilled water that is still in the engine. But that can take hours and you may already have the premix pink. Just use it.

    The concentrate isn't available either in Europe as far as i know. This is the premix stuff (08889-80072).

    After i put in the new stuff, i put the car in maintenance mode. But the cooling fan never turned on. The outside temperature was around 22C/71F. I monitored with my OBD2-tool, the coolant didn't get any hotter than 86C/186F. I let it idle for quite a while, but after 20 mins. i had enough of it (and didn't want to annoy the neighbors with noise any longer).

    I think i just have to monitor the level the following days after i have driven some distance on the highway.
