I don't think that's for the coil springs on the AD links.
Anyway, it doesn't specify what that tool will work on.
As far as I know the spring is not servicable separatly, at least I haven't been able to find the spring listed.
The new link assemblys are only about $35 and most of the vendors carry them.
I think most of the time the hood is simply maladjusted and it's not the spring that's at fault.
