Three screws holding the cooler, unclip, disconnect and lift up the engine control module, unclip the three tubes in the corner of the cooler, loosen the big hose clamps on the front of the engine, loosen the cooler connection on the other side, pull the cooler towards the front of the car and then fold it upwards. This way you don't need to drain the intercooler coolant. Then you need to loosen the aluminum intercooler bracket, after this you can access the intake manifold pressure sensor.
