My 2007 GXP turned 5 late last November so the coolant needs changed. I've been waiting for better weather to do it myself. I've seen the thread on how to fill the system but nothing on how to drain it. Is there a petcock on the radiator, are there drain plugs in the block? Can anyone give me some help please?

The drain release on the passenger side is real easy to get at. It is a white plastice valve. most fluid drain pans will slide right under the radiator.

Charlie, let me know how you do, I had my coolant flushed by the dealer on my 2007 GXP in January. Now my temp readout fluctuates between 195 and 207 where is use to always be 198-199.
Tim-
If your temp is sporadic, you probably have an air pocket. There is very detailed info on that on here as it is not simple to fill the Sol and not allow air into system. It is also tedious to get air out. Something like driving one tire onto a 2x6 or something. If your temp is consistently higher, then the new coolant is not as good as previous coolant which would mean the mixture is different.

Yes, that was my first thought and I did the bleed process documented on the forum. I got fluid coming out of the line that connects to the top front of the engine, when I squeeze the large hose, it will blast out into the reservoir tank. This process lowered the fluid level in the tank by 1/4" inch. So now instead of the temps fluctuating from 190 to 220, they just go from 195-207. I'll try the bleed process again and see if I get anymore air out of it.
