Concentrated Ethylene Glycol Coolant
Discussion
Hi All,
I am due a coolant change on my GSX-R 1000. The last time I did this, I could buy 1L of concentrated ethylene glycol coolant to fill the radiator along with distilled water. However, I am having trouble finding concentrated stuff...even Rock Oil (who used to sell the concentrated stuff I used last time) now sell pre-mixed stuff.
I do not want to pay a premium for pre-mixed stuff so would like to ask if anyone can recommend a concentrated coolant?

Thanks for the replies all.
I ended up buying this Autochem ethylene glycol concentrate 2L for £5.49, but have not yet put it in. https://www.tetconnect.com/winter_range/antifreeze...
It contains DISODIUM TETRABORATE PENTAHYDRATE (Borate) which is the corrosion inhibitor. The Febi Bilstein coolant linked to in an earlier post contains borate and phosphates. The internet is full of different information about whether silicates, borates and phosphates are bad for motorcycle engines. As far as I can tell, the Autochem ones has no silicates (which supposedly damage water pump seals), but I am no chemist so not sure how I would know if it contains silicates or not.
I personally feel that I am reading too much into this - after all, the GSXR service manual just states to use a 50:50 mix of EG suitable for ally engines. It does not say anything about which corrosion inhibitor should be used or avoided.
