Quick coolant flush question
I bought my 04 in Oct. of last year with about 96k on it and knowing basically nothing about the maintenance history of it. Its at about 101k right now. I installed a Sinister coolant filter at about 98k-ish. When I changed the first coolant filter I expected it to be full of garbage since I had no idea about the status of the liquids. I was surprised to see that when I cut it open, there was absolutely nothing in the filter. Super clean. When I run it on the highway, I don't tow anything so its unloaded, the temp is usually about 188 with the deltas typically being 0-2 degrees, the highest I've ever seen was 5 and very briefly.
My question is, do I need to do a chemical flush (Restore, Restore+/VC-9), or would just a good distilled water flush work since my filters are clean and there's not a big temperature gap?
