There are 2 guide pins; one obvious one, which forms the pivot for the serpentine belt tensioner spring; and one less obvious one, directly beneath the top hose outlet stub.


In return, could you confirm a point for me about vacuum pipe routing? There are two valves fastened under the inlet manifold, which control the resonance flaps. Does the white/green vacuum connection go to the 2 forwards pointing ports, with the black, atmospheric, connector to the 2 rearwards pointing ports?
