2000 grand marquis runs hot withend 10 minutes of driving it

Hello, it would be nearly impossible for this engine to develop an internal engine coolant leak that would cause white smoke to come out of the tailpipe. I guess anything can happen, but highly doubtful. Is the engine making internal noise, such as from internal damage? You just need to take the car to a shop near you for even a preliminary inspection. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
