[DeTomaso] Radiator installation

[Forest Goodhart]

Actually it is quite the opposite. Silicone hose will last virtually forever. That is why it is used in spite of the issues with clamping etc. It is important to use the correct clamps so that no physical damage is done to the hose. West Marine is one source of proper clamps and  the hose vendor that sells silicone hose should also have them. The European clamps that were originally used on my car are also good for silicon hose as the slots the screw works on are pressed in rather than punched through. It is the sharp edge of the holes that cause the damage. Forest

  are not part of their design brief.
  They are not nearly as strong as quality conventional rubber hoses; in
  fact they are so fragile that conventional clamps can/will cause them
  to fail.  If you don't tighten the clamps so that you're protecting the
  hoses, you're inviting leaks, or worse yet, a hose popping off
  completely.  If you tighten them enough to ensure the hoses stay on,
  you'll likely damage the hoses--if not immediately, then over time
  (through heat/vibration cycles).
  What inspired you to switch from quality rubber to faddish silicone
  hose?  At a minimum, I would say if you plan to keep them, you should
  buy the (high) number of (expensive) special hose clamps to attempt to
  preserve your new hoses as long as possible.
  But if it was me, I would be ditching them in favor of OEM-quality
  rubber hoses, which have a known (good) track record and (long) life
  expectancy.
