Coolant change concerns
First off, Hello, I am new to your forum & to the HHR. I recently bought an 2007 LT1 for my son. The car has 100K on the clock. I don't know when the coolant was charged, if at all. The manual has all kinds of warnings about "take it to the dealer for coolant change". I am a pretty handy guy with access to most tools. What is the concerns with changing the coolant? I have been through the majority of the treads and used the advanced search, but I don't see anything that speaks to any specific "gotcha moments".

Welcome!
The reason to take it to a dealer is that they should have a machine that does a complete flush and refill. Many don't really use it.
If you do it yourself you may end up with an air bubble in the system. Not a big deal.
The Service Manual say "Don't use chemical flushing agents".
Replace the t-stat and use 50/50 Dexcool only.
