I should have probably had that done before the blower went on. I wonder what they will say when it goes in with the gauges and blower?

Thanks FLATOP08, I really hope the dealer does not give me **** when I take it in. Since the clutch fan and shroud are not there anymore. Knowing some dealer they will probably say not having the fan shroud caused that clunking noise.

My dealer loved the e-fans. They were a little questionable about the headers, but they loved the fans. They compliment me everytime I take it in on how easy it makes it to work on the truck.

Since they are obviously not related ... they can't *by law* deny you that. I went head to head with the service manager before because he tried to tell me that the supercharger caused my power steering problems, and he wasn't going to replace a headlight with moisture in it.

P/s pump was replaced, and lights were replaced after a few phone calls to the GM Customer Service line.
