Sorry, folks, possible dumb question time. How hard would it be, really, for me to flush my own coolant? It's for the Monte Carlo, 2004, and I would be sticking with the Dex. I had it done once at the dealer at about 50,000 miles, who charged me something like $150 for the pleasure. I'm at a little over 102,000 miles now, so I figure it's about due again. I'm flipping through the Haynes and stroking my ego, and I think armed with some distilled water, Dex, GM sealant pellets and a bottle of wine, I could just do this myself and save the change for a Scangauge, since my awesome stock gauge cluster is tanking for the second time. The LIMs are still original. So, what say you, BITOG? Easy peasy, or let someone who knows what they're doing at it?
