Open your hood, and physically check your coolant reservoir. Make sure that your coolant level is between MIN and MAX lines. If it is not, please add coolant to level.
Start your engine and look under the engine for possible coolant leak. If there is no leak, drive the vehicle to your local parts store (such as Autozone, CSK/O'Reilly) and have them scan your computer for codes. Get back with the codes.
Is the engine still making that rough sound? Is your engine oil at level as well?
