Warning: This is a step-by-step video for anyone that is new to doing this. The video is long and covers all aspects. Follow along as I do a DIY coolant flush on my 2008 Chevrolet Colorado using Dexcool. I show how I drain the system, flush it out, and disconnect the lower radiator hose. I have close to 200,000 miles on this truck and it’s been nearly 100,000 miles since I had this done last. I learn a lot on this adventure, but, it’s very time-consuming as you must wait for the engine to cool between the distilled water flushes.
