I'm not sure if i spelled that right... but its called plenum or something like that and its leaking anitfreeze horribly and i was wondering if there is a website where you can get a diagram of how it looks takin apart or how to take it apart so we know what were dealing with. we are going to change it ourselves but we want to have the diagram as a reinforcement. any one know how to change this gasket or a website that can help but showing us pictures and steps?
