I'm am going to be replacing the coolant temp sensor in my wifes 2008 Pontiac g5. I'm know that I need to drain the coolant down a bit but I am unsure of how to do this. I have the new sensor and wrench ready, I just need a little help draining the system. How much, and when, should I fill the coolant back up when I'm done?
