For those that remember doing the install, does this hose replace the coolant line that runs between the bottom of the throttle body and the intake manifold? I remember the instructions stating something like, "connect... to the throttle body or the fast idle thermo valve, and either the intake manifold or the water outlet neck." If it does replace the coolant line, does that mean the stock breather hose assembly along with the 2 welded connecting pipes are removed from the car completely? Thanks
