My Dakota is making a chirping noise on deceleration and at idle. It pretty much only does it when the throttle blades are closed. Noise seems to be coming from the area of the A/C compressor. Only does it after the truck is good and warmed up. It will make a whistle when the key is shut off, and will sometimes whislte after the motor has quit turning. I am inclined to think vacuum, but I have checked every hose, and gone all around the throttle body with WD-40 and can't find a leak. Any clues? Thanks!

I put a cheap belt on my durango and it started doing that, though it must be a pulley and replaced the one it sounded like it was comeing from, no luck, replaced the tensioner no luck, swapped altenator with my dakota, no luck put on a "premium" belt and no noise.

I put a good belt on it about a year ago. I've thought about the fan clutch too, but I have watched as the motor is shut off and heard the noise after the engine and fan quit turning. I'm going to take it down to my shop Saturday and pull the shroud for a closer look-see. Thanks!

Check the blt tensioner too. If it is seizing up the belt can chirp. With it running CAREFULLY reach in with a 15 MM wrench and pull it a little tighter, and if the noise goes away it is the tensioner.
you have to do it with it running because the starting torque moves the tensioner.

spray a little water on the belts. It should quiet them down if that's what it is.
If you ever find yourself in a fair fight, your tactics suck.

And the winner is.............................. Curt with an honorable mention to Lonnie. Got to thinking about this on the way to the shop. I remembered that I changed the breather hose from the valve cover to the intake on my K&N a couple months ago. I wasn't real fond of the way the hose routed under the bracket but forgot about it. The hose was kinked and had fused itself shut. Pulled the fitting/grommet out of the valve cover and a huge "WHOOSH" greeted me. I rerouted the hose and made sure it can't kink, no more chirp. Thanks all!
