Re: Alternator....?

Get used to alternator failures. I've had 3 in 112, 000 miles. As I understand it, one group of GM engineers (the underhood guys) lied to another group of GM engineers (the alternator development team) about the underhood temperature that the alternator would have to cope with. So the alternator is forced to live in an environment much hotter than it was designed for.

As you might expect, the alternator is a fragile design anyway, having a terrible reputation for early failure in ANY application it was used in. Couple that to an extreme environment, AND burying the thing so far down that you need dynamite to remove it, and you've got a world-class screwup.

Thanks GM.

You might try the Iceberg conversion kit. Includes more heat sink area, and a larger rear bearing. Both of those were known problems with the original design.

Ten trillion to start with, increasing as needed from there, PLUS compensation for the sickened, and "wrongful death" settlements for the families of those who didn't survive. END trade with Communist China.
