What do you do with the a/c manifold once the bypass pulley is in ?
Hunter C November 23, 2016
you can use cable-ties to secure it out of the way(which is what i did) or remove it from the vehicle. if you decide to leave it in the vehicle make sure it will not come in contact with any hot or moving parts.
