I've had my '07GT for a few weeks now. Thought I would check the coolant level. Checked the owner's manual, and could not find any information on how to check. With the help of my salesman, i found the overflow tank. I cannot see any fluid in it hot or cold. I removed the radiator cap and added some water but it did not seem to go into the tank. I have not picked up the $135 maintenance CD yet. The 600 mile service has been done and i have not had any overheating problems. Any thoughts on this?
