Right as my car has a tendency of running g quite hot and the lack of an expansion tank it sometimes spray water out of the boil over and with the coolant being pink keeps making a mess on my clean gearbox and shiny bay.
Now the question is;
I have seen some aforementioned clear/colourless coolant but cannot remember where. Has anybody heard of this or did I dream it??.
Please help. I'm fed up of scrubbing my box with a toothbrush.

Cheers J
