Can U pull alternator pulley while still in van?
06--3.8--caravan

Thinking about removing pulley on alternator while still on van. . Still don't know if that is why my engine sounds like a diesel. NO malfunctions exist. If i do decide to do it, i would like to pull if off while still in van? I wish there is away i could isolate if the sound is coming from the alternator. I tried to listen with hose and sound appears in 3 places.

Have you ever pulled the pulley off the a/c compressor while still in van? Maybe I will pull the bearing out of pulley and replace and see if that gets rid of diesel sound?

 

not what you have but some have just a bearing with a screw thru middle. theres another u need a special tool to remove it. it has a special feature like a clutch of sorts and clutch does also make noise. damm caint think of name right now.

 

Is the pulley called "decoupler"? I wish I knew for certain if it were alternator pulley or a/c pulley. Removing the belt gives me a perfect purring engine.
