Re: Silicate Free Coolant?
Silicate and non-silicate-based coolants don't mix well. In fact, they're considered non-compatible. It appears that even a small cross-contamination will impact protection.
There seems to be chemical incompatibility between the two, resulting
in corrosion inhibitors falling out of suspension. It's believed that the acids in the organic
non-silicate coolants will tend to cause residual leftover silicates to fall out of
suspension. Apparently, this will affect corrosion protection and possibly add
(how much I don't know) to silicate-caused negative results.
I can't see it corroding in a single riding season (esp here in Boise), so I say ride and then change it before winter.
