Oh just googled it and found this
http://www.forumapex.com/other_modding/5555-glitter_in_the_water_cooling_system.html
Apparently ethylene glycol which is bright green is safe to use.That was take from in the link.
I have no idea at all myself![]()

Well on that site there is a section about extreme cooling so may be worth you having a further read m8
But you may be back 2 square 1 .Plenty of info on there for cooling mixes and stuff though![]()
but will those dyes flow around in the kind of style im looking for?
DO NOT add anything to the system that isn't a pc coolant, it could nay WILL corrode it!
you can buy dyes or coolants with dyes in but you won't be able to see the flow as they will mix. the best thing to show flow is surprisngly a flow meter.
