Help with new noise.
Comeing from under the hood. The best way to describe it is it's kind of like what tire chains sound like from a distance when some ninny is driving with them on dry pavement. Quieter than that but close and it kind of pulses. Either lessens or goes away after a good warm up. Is this one of the pulleys I've heard of that occasionaly likes to be replaced?

There is an air pump that could be making some noise. It's actually a vaccum pump I believe and its purpose is to operate accessories in the cab like the heater/AC vents. Mine makes some noise on occasion. It's more noticeable when you have your windows down. It could be a pulley as well.
