Does the spring clip on the heater control valve clamp down over the silver cable or the black sheath that the steel cable is in?

If it's the sheath, the clip looks two sizes too small and I'm guessing I need to use some sort of tool for this.

If it's the cable, I've tried that and the result is almost zero travel when trying to adjust the thermostat in the car (slides fine when spring clip is not in place)

Car is early 944 (1984)

Thank you in advance for any help.

Spring clip clamps over the black sheath, not the wire. For me the edge of the metal clip was lined up with the edge of the black sheath. The indentation left in the black sheath was also a clue to the proper placement.

Yes the clip is a PITA to get over the cable correctly. I think I used a pair of pliers to generate enough force. Problem is you risk breaking the plastic housing on the control box.

Be sure you are attaching the correct cable to the proper control arm. The black cables are easy to mix up. I should have marked mine :-)

Thanks. Did you attach the cable as a final step or before the hoses were connected to the HCV?

My car had a cracked plastic housing on the control box. I would probably attach the cables as the final step.

The clip has two humps, the sheath should go into the hump closer to the "back" of the clip where it anchors in initially.

One trick I developed for getting this PITA clip on is to punch a little hole in the front tip of it, and use a little pick tool through this hole to help you pull the clip on.
