I inherited the job of finishing a Charger Daytona most everything's done but beings I did not take this apart and have no experience with these headlights does vacuum pull it shut and raise it open and how are they open in default? the real question is how do I clock the springs on the back side before I put them to the bracket and bolt them down I honestly don't think I'm supposed to wind them springs up till it opens the headlights that seems pretty extreme so I just need somebody to school me on how that works thank you very much! As of right now I have the springs and clips on there and the bracket that holds the spring in the headlight doors are down I'm sure the answer is fairly simple but like I said I hate being into somebody else's project but it is what it is.
Vacuum holds the doors down/closed, and also raises/opens them, the "safety" springs located inboard on each light bucket/pivot shaft, were intended for emergency use to raise the lights, should the vacuum system fail in anyway, shape or form, the factory instructions were to disconnect the 2 harness lines located atop the radiator yoke, by disconnecting the 2 lines from the pressed in inline connectors/unions, this would release any residual vacuum left in the forward light harness/pods, and allow the springs to open the lights, which it did, although not a very practical system, it was enough to perhaps offer some light for emergency night time driving...
The springs are often the cause for these cars having the "lazy eve" syndrome when parked, as any leak in the vacuum system will cause one or both headlights to slowly creep open, most owners disconnect or remove the safety springs...
to install the safety spring correctly, leave the headlight door in the closed position, install the spring,looking directly at the pivot shaft's end, the keyed slot that accepts the spring should be facing slightly reward towards the rear of the vehicle (2 o'clock position if looking at passenger side, 10 o'clock if looking at driver's side)install each inboard spring with it's curled tail end upwards and both tail ends (drivers/pass) facing the rear of the vehicle, you need to remove the bolt/nut and angle iron bracket that tensions/retains the spring's tail end, invert the bracket, hang it on the tail hook of the spring (like you would hang a decoration on a Christmas tree)now carefully wind the spring clockwise on the passenger side, and counter clockwise on the drivers side(looking at the pivot shaft end) by using the angle iron bracket to tension the spring, it only takes one revolution, it takes a little effort as your now lifting the head light door, once you have wound the spring tight, if you hung the angle iron bracket in the right orientation, it should now line up with the hole you removed the bolt/nut that retain this bracket, install nut/bolt and tighten bracket, your done, the light should be in the open position...
