i am researching whats all done to my new car and cleaning up the engine bay. can anyone give me hose diagrams for coolant lines, vacuum line and breather lines? it would be much appreciated. one thing I'm questioning is there is about a 2 in hose that comes out of the intake manifold and goes to what looks like some sort if diaphragm. this diaphragm has a nipple coming out of it that nothing is connected to.im wondering if it is supposed to be that way or if i need to connect it to something? thanks a lot.
