CONDUIT CLIPS (OVAL) 103003
These are replacement Conduit Clips for the oval conduit
*SOLD AS A PAIR*
The problem begins when the plastic clips break. This allows the oval conduit to sag and drop down in the engine bay, eventually contacting the down-pipe. Once this happens, the heat from the down-pipe quickly burns thru the harness conduit, contacting the wiring, quickly destroying the harness. Replacing a burned $800 harness is not a good idea.
Why does the plastic clip fail? Three factors are involved: Original design, material used in the part, and age. The factory design involved a square flange and a single mounting bolt. Early failures were found where the square flange breaks, placing the entire weight of the copper-filled conduit onto the single mounting bolt. Since the upper part of the clip is a “forked” bolt mount instead of a “closed” mount, the excessive weight along with engine heat caused the forked opening to spread, releasing it from the mounting bolt, finally dropping off altogether, causing a sagging appearance in the conduit. The weight of the harness constantly pulls the harness downward and quickly contributes to the failure.
The material used in the original production run (early 1986) had less glass fill in it and was prone to softening with engine heat. Around early 1987, GM discovered the problem and ordered a material change, requiring a greater glass fill and a higher temperature plastic material. Thus, the late production cars had a more reliable part. However, the years and accumulated heat have taken their toll on the clips and today, most if not all of the existing parts in service have failed. The parts supply has dried up and the later version of the part is now long obsolete. Although several years ago, there was an aftermarket steel replacement part available, but that too became obsolete.
