Dexcool coolant warning

Stupendous Man · 2007-05-17T04:32:47+00:00

After learning that silicates (powdered quartz) in coolant kill Honda bike waterpumps, I have been running Dexcool in all my vehicles, not wanting to spend $30 for Hondaline pre-mix once a year.I didn't think too much about it when my VW diesel blew a headgasket last fall with less that .0015 In. warpage. I have ben running Dexcool in my Goldwing for 3 years, and it blew a headgasket last month. I found less than .001 In. warpage and the gaskets where they were free-standing in coolant had all the material either gone or blistered up badly. A short Google turns out that lots of people have had similar problems.I changed the coolant in the other 6 vehicles.
