I have been working on the broken underbody panels for a couple of days.
Repairing underbody panels
Yesterday I pulled off the front bumper cover to:
1) clean the radiators... wasn't really necessary, they were pretty clean but now I know.
2) reroute the cable for the frunk latch. I prefer to have it where I can find it without removing the fender liner.
3) replace the fan ballast resistors which are shot on both sides, which means no low fan speed.
Here is one of my DIY resistors ready to install
4) add screens behind the air intakes to keep leaves etc. out of the radiators in the future.
The Boxster's low ride height takes a toll on the bottom of the front bumper cover as well as the underbody panels. Like other covers that I have worked on many of the anchor points are broken and various fasteners are missing or have been added to replace the missing ones. Later I will have to go back and add the missing fasteners and fix some of the broken anchor points.
