ROWDY XOC Posted January 6, 2022 Share Posted January 6, 2022 I'm sure this topic has probably been exhausted but please bare with me. I use a modified air conditioner to cool my loop which never normally gets close to sub zero temps, However due to this recent nice and cold UK wintery weather yesterday the coolant in my res turned to slush! big panic my side as you may imagine! So my question is, is it ok to use Antifreeze in my loop? Its not something I wanna gamble with if it has the potential to eat away the seals over time in my water block etc. If anyone has any advice or experience with this it will be greatly appreciated. ? I'm using Ek supremacy block (acetal) D5 Pump Soft tubing EK Res Quote Link to comment Share on other sites More sharing options...
Mr.Scott Posted January 6, 2022 Share Posted January 6, 2022 (edited) Window washer fluid, not antifreeze. Also, you're now running a chiller, so you better be stating that on your subs. Edited January 6, 2022 by Mr.Scott 2 Quote Link to comment Share on other sites More sharing options...
ROWDY XOC Posted January 6, 2022 Author Share Posted January 6, 2022 That’s a good shout is this something you have run? Also what is the main benefit of using screen wash over antifreeze, I assume it’s less aggressive? Thanks! I have listed all my subs with air conditioner as “chilled” ? 1 Quote Link to comment Share on other sites More sharing options...
Mr.Scott Posted January 6, 2022 Share Posted January 6, 2022 I run it in my chiller. Been doing it for about a decade. It's has less viscosity. Way easier on the pump and keeps the flow rate up. Good to roughly -30 or so. Quote Link to comment Share on other sites More sharing options...
ROWDY XOC Posted January 6, 2022 Author Share Posted January 6, 2022 That sounds just what I need, Thank you for sharing! Just to double check would you advise its ok to use over a long period of time I normally renew fluid every 12 months or so? Quote Link to comment Share on other sites More sharing options...
Mr.Scott Posted January 6, 2022 Share Posted January 6, 2022 Been at it a decade. I only top mine off as needed. Change every year can only be better. 1 Quote Link to comment Share on other sites More sharing options...
