There is a metal hose connected to the part (just below) the exhaust manifold. Its a silver pipe that is connected to the start of the exhuast pipe in the engine compartment. The mechanic had taken it off, and said it really doesn't need to be connected, because we live in the california desert.

But before I knew that, I had reconnected it to the car....because i was checking the engine just for the sake of it.

Here's the question, Should I diconnect it again because of the heat?

thanks
