Mixing different kinds of coolant.

realscot · 13 May 2011 at 07:50

I currently have Fesser One coolant in UV red, it's getting a bit low though and could really be doing with a topup.
What's the opinion on topping up with another brand of coolant? could it potentially cause an issue reacting with my current fluid? or is it like a car cooling system where you can really add anything?
I've never had to topup in the 2 years + i've ran this loop which is also my first ever w/c setup so any advice would be great, cheers.

After two years you could probably do with draining it, flushing everything out and giving it some fresh coolant. Other than that just top up with distilled water.

+1 - I'm using Thermochill EC6 they recommend to change it every 2 years.

I was looking at that thermochill EC6 on a competitors site, seems decent value for money. I never realised the coolant would go off that quickly. What should I flush with, plain water? or a few litres of cheap de ionised stuff? I can get that for nowt at work u see

never use plain water, use Distilled

Flush with plain water then a final flush of de ionised water.
