After reading page after page of Dexcool bashing, I have considered making a switch from Dexcool. I flushed my coolant last year. The car was at about 37k and the coolant looked about as clean as you could ask. I don't believe I read much about Dexcool causing problems in these engines, but I could be wrong. Are there any risks in making a switch to a non-dex coolant like G-05?
