I have an '08 SRT8. When I start it on a cold morning (below 20 degrees), it makes a quick "whoop" sound just as the motor kicks in. I don't think it is the serp belt b/c it doesn't do it as the starter is turning the engine...it makes the noise right when the motor starts running on its own. It won't do it if it's warmer outside or the engine is warmed up. I'm guessing maybe the master cylinder or power steering pressurizing. Any ideas?

Every GM vehicle I owned from about 1981 on did this but I've never heard it from the Challenger or Jeep yet.

Thanks guys...I thought I was going crazy...sounds like it might just need time to "break in". Although she's an '08...she's been in storage...so we've only now passed 4000 miles

I drive my 09 every good weather day and it only has 6000 miles. Gives you an idea of what the weather has been like the last 5 years.:shakehead:

You've got a solid point there. I've heard of folks using blizzak (sp) tires so they can drive their rig in the winter...they just go so overboard with the salt in my area. The running joke is that you need 4wd to get through the Arlington, OH salt mounds.

It looks like the noise is the power steering pump pressurizing. There is a "one liner" about it, in the manual, under power steering. Basically says it will make a noise when you start the engine during cold weather, because the fluids are thick.

A possible solution to that would be to switch out the fluid with a quality synthetic ATF fluid like Amsoil, Royal Purple or Redline.
