Mine sounds like that or just a bit quieter.
Yes that's basically what my '21 sounds like on cold start. I actually notice the squeak more as the rpm drop back under 1000.
gtfo you add nothing to any thread you respond to
I know this is an older thread but alot of times a chirp on start up is an indication your clutch fan bearings are seized...might need a new clutch for the fan...
So your telling me easily 50%+ of brand new 6.4 hemi trucks straight from factory need new a new clutch fan because bearings are seized? No. This would have been figured out long ago. There is still many theories on why or what the fix is but nothing for sure. This has been a known sound or "issue" for years with these motors. People have ran their 6.4 for years with trying everything out there from the manifold to y pipe, bearings, belts, etc. And still nothing worked still chirping. You either get lucky or you dont.
Army19kilo - If you read more toward the beginning of this thread, or several other threads on the 6.4 chirp issue, you'll find that it isn't related to the normal mechanical stuff we'd check when hearing this noise. It is a "feature" of many/most 6.4's, new or otherwise. Some just do it when cold, some all the time at idle. Mine has done it since I've had the truck, bought it with 7,700 miles and now have 90 on it. Most likely something in the exhaust configuration, to my knowledge nobody has found a "just do this and it's gone" fix for it. Doesn't particularly bother me, but does bother some people quite a bit.
