Hi,
What does this mean? I looked up the diagnostic on your site. But, does it mean I need a gasket, filter? Just looking for a little more info. so I can be well informed when and if I take it to a repair shop.

Thanks,
Lynda

It means the engine is running too hot, can be low coolant, bad thermostat, or anything that will cause an overheat condition. If it's a 4.6 these developed a leak in the front upper intake manifold. You may need a pressure test.
