The temp light starts blinking when I'm driving 55 or higher. When I drive at lower speeds then the light doesn't come on. I checked the coolant and it's fine. Any ideas? Any help would be greatly appreciated !!!!

Water pump is faulty. .... get it replaced soon along with your timing belt and tensioner.
