That's the factory s/c pulley. The crank pulley is the very bottom center pulley. It's the largest one on the engine and both belts wrap around it.

they change that to after market to? cuz the guy who sold me the car said he had "upgraded pulleys" heat exchanger"(what exactly is the heat exchanger for?) and headers,

new211e55owner

in the pic i posted above the heat exchanger is the big idem on the bottom by the fog lights?

Try to get a pic of the rest of the pullies because those 3 in the pic are stock. The headers are on the sides of the engine under all the spark plug cables. Get a pic of that too. Yes that is the heat exchanger and it helps to reduce intake air temps.
