[s-cars] Radiator cooling fan won't run

[Tim Leonard]

There was no cover nor was I aware there should be one. Thanks for that
info. For now I soldered the link together as it had corroded in two rather
than blowing in two. A shot with the bead blaster cleaned it up well and the
pieces mated nicely. Thanks for the part #. I'll order from FLAP (person).
