Is the squeak when the engine is killed the belt or what??

Just wondering if anyone knew.

While I don't know the answer, but it must be a common problem, because mine has the same described "squeak". I also hear it when I go over bumps with the windows open. Its not as annoying with the radio on though

Anyone know what the "squeak" is , I'll be willing to know too.

my brothers '01 cummins has a loud squeak when he shuts it off and he tells me it is the belt. common sense leads me to believe this is true.
because of the high compression ratios in diesel engines they stop rotating very quickly when shut off. all those rotating accessories must also come to a halt or they may rotate a bit more after the engine has stopped causing the squeak. this sounds believable but it is a theory i just came up with.

 

Sounds like a good theory to me !

That's the theory I have too - guess since two of us have it, it must be the truth eh?

 

A guy where Iwork just bought a 2002 dodge cummins and it also squeals when shut off. I told him he should at least go back to the dealer and ask about it. He did and that is the reason they gave him. It was the belt because everything was coming to a halt so quickly. They walked over to another gentleman who was there with a dodge and they asked him to start it and shut it off and it did the same thing too!!

I'm guessing this is more of a problem with the Dodge. I havn't heard much about it from the Fords and mine does not do it. Thats not to say it doesn't happen to some though.

 

Roomates Cummins does it every time. My PSD never does. Now my F-150 with a 302 squeaks on startup. And it isn't the belt. Wish I knew what that was.

My PSD did the squeak thing 'til it got some miles on it, then stopped. I figure like you guys, just everything else coming to a quick stop.

Dad's truck does it too every once in a full blue moon. It also gives a squell on a high RPM shift with the fan turning. It'll do that on a hot day every once in a while.
