> Does the Bentley have an illustration of these inserts? I'm having trouble visualizing what you all are talking about. Are they just sleeves that fit into the ends of the plastic tubes to reinforce them at the clamping points? Why do they slide out? The inserts are corrugated and the plastic is molded onto it. My theory is this: Pressure from the hot cooling system causes the clamped hose to pull against the lip at the end of the pipe. The metal insert is supposed to help spread the strain, but the plastic gets soft... it cracks behind the lip, and the steel insert loses its grip on the now softened plastic.... and millimeter by millimeter it works its way out...
