The Denali is in need of some attention to the cooling system.
I replaced my oil pan January of this year due to a leak. The previous owner did the gasket before me and the work I saw was shoddy at best. He also replaced the water pump......
I am not actively over heating, but, if I sit for an extended period of time >20 minutes idling the gauge starts creeping up. Also, I am having a weird engine stuttering issue that a coincides with a loss of ECT gauge functionality.
I plan on replacing all major components and ECT sensor, checking wiring and ECM grounds. Doing the block flush by removing the drain plugs to try to remove as much old coolant as possible. My main question is, should I do a chemical flush as well? Something similar to this product:

I vaguely recall a friend of mine doing this and blowing a head gasket on his 02 Silverado. I have also heard of people using it with great results. I am leaning towards using it since I am doing the block flush as well.
Thoughts, opinions, facts, horror stories welcome.
Thanks
