noise in engine compartment
2003 town and country
noise at idle like a bad pensioner bearing or idler pully bearing . i have checked and replaced the belt and the tensioner ,i have checked the idler pully and the a/c compressor bearing, the water pump and pulley bolts. noise goes away off idle. i worked for GM dealer for some 30 years and it sounds like crank pulley bolts loose. or a dry or cracked belt. these items have been replaced or checked.possible its in the power steering area. but its not a mone or whine or squeel .. i also removed the resovoure and cleaned the filter screen and replaced the fluid. got me stumped

It might be the "Alternator Decoupler Pulley" check out this post: Two noise but not sure what they are from.
