What is a “pump lining”? The high pitched grinding noise when the wheels are turned sounds like you’re low on power steering fluid. The air working on max only (you mean the fan only running on max, right?) is likely the resistor block for the blower motor.
How much “smoke/steam” is coming from behind the engine? Does it only do this when you turn the wheels? If it’s dripping, what color is it? Where exactly is it coming from?
