    Q:
    How do you raise the engine to clear the Engine Mount studs for the 2013 Toyota Highlander? Posted by Gabriel E.
    A:
    Carefully raise the engine until the engine mount studs clear the subframe, then remove the nut from the top of the mount and angle the engine mount from the vehicle. It may be necessary to loosen the other mounts at the subframe to raise the engine for extra clearance. You can Select Your Vehicle to see complete installation and repair tips.
