Engine/Transmission (1998.5 - 2002) New Noise

[DIESELWRKS]

okay on start up when the engine is cold and temps are in 30s/40s I get a squeel to a high pitch canary sound goes away usually in 5 minutes I tried to isolate the sound but the truck is just to noisy to isolate. so I'm guessing the best way is with a cold engine remove belt and check the idle bearing and the water pump see if there is any play. does the fan/clutch make the same sound or would I see a different issue if it was the fan/clutch. I know genos sells a dayco bearing its cheap and I checked the water pump on rockauto.com but what about cummins water pump should I look there first. I replaced my belt about 25k miles ago I guess it could be that but looks good. so tell me you thoughts or if you have a different way to trouble shoot this. my water pump is not leaking.

Probably the belt, but if not the power steering pump reservoir may be low & the squeeling may be air in the system.

Quick and easy trick to see if its the belt or not, get a cup of water. As the engine is running and the squeal is doing its thing, pour a small amt of water on the belt. If its the belt, it should stop for a few seconds and then start back up. If the noise doesnt stop with the water... its somewhere else.

Over the years of working with cars... ... 90% of squeals that are coming from the fnt of the engine are belt related... ... usually you hear a lower pitch, or grinding if you had an issue with an idler, alt, AC, PS pump (Which is gear driven... . wait... which gen do you have? 3rd gens are belt driven. ) or WP. AND if the water pump is far enough to make noise... . more than likely it will start to leak... or is leaking out the weep hole... . NOW im not saying that you cant have squeals with those items... ... but you should be able to isolate by pulling the belt and spinning by hand.



Look for funny ware on the belt as well. ALSO eye all the pulleys to make sure alignment is straight.

thanks for the input I will try this when it the next non rainy cold day. but not like the cold out your way. I was stationed at Ft. Leonardwood Mo. I will check my belt it is pretty new but its a cheapie belt.

25,000 miles is a fair amt on a belt..... I change mine every 30,000-40,000... ...

Try flushing the power steering system/up grading to a synthetic.

That is what I did, noise went away.

I will try the power steering fluid idea I didnt think about the steering because it would make this noise at idle and not moving

You can test for that very easy... ... run the engine with the belt removed (Do this on a cold engine). If the noise still there..... you only got the PS pump, VP-44 and vac pump..... and VP-44's are not known for thoes noises... ... Then i would look into the fluid change if you find it coming from that area... ...

Thanks for all the replies glad there are those of you like this out there.

No prob! Kinda fun to go back to the old days every once and a while and troubleshoot something besides a FASS! haha... . :-laf
