Alright, the coolant on the gxp is at 5 years and 18k miles. From what I have gathered, this is not something that can be drain and fill but needs to be done with a machine to prevent air pockets. My only problem is, the Pontiac dealer that I trusted is obviously gone. I need some advice on a gm dealer in my area that I could trust. I contacted one but they don't have the machine to flush and fill, the other told me "we are a certified GM dealership" when I asked if they have ever worked on a LNF motor or GXP. I don't know if he knew what I was talking about or what. Any info would be great. Thanks.
