Strange noise when my RE22 has warmed up

    My little RE22 Automatic runs as smooth as silk. But, after it warms up it has a high pitch squeal while idling when stopped. The squeal stops immediately when the rpms increase. It's not the belts, and if it where the bearings in the pulleys I would think it would get worse when you give it gas. I can't pinpoint the origin as it seems to come from everywhere when the hood is open. If anyone has the slightest idea I open to try. TIA

    The idler pulley bearing is know to fail on these and will make a high pitch noise at idle sometimes as RPMs increase the noise can go away. The bearing is fairly easy to remove and cheap. I’d start there.

    @OR17TRD, Thank you sir. I bought one of those stethoscope thingys at good old Harbor Freight yesterday. That will be the first thing I check. Buy easy would that mean a "shade tree" mechanic like me could change it out?

    Update: OR, I used the stethoscope to check the noise. As the power steering pump, and the idler sit on the same bracket it was a hard read. But, I went with your advise and ordered the idler pulley as it is a known problem. The old pulley does have a little side to side play so I think I'm in the right place. And you're right. That will be an easy fix. Thanks again for the tip.

    I will my friend. The way these pulley's are listed at the parts stores I'm hoping I got the right on the first try. :)

    OK, the Dayco Idler pulley #89039 fit as it should. The pulley has sealed bearings which is good because I had to scrap the original dust covers, and the old bearing sleeve. The only thing needed from the old setup is the large washer for the back of the new bearing to line everything up. I'm gonna take the truck on a shake down cruise in a little while, and hopefully it will be as quiet as a church mouse after she warms up. Fingers crossed.

    @OR17TRD, well as the saying goes "there's no joy in mudville". It wasn't the pulley. With my at best shade tree mechanic ability I gave up , and took it to our local foreign car mechanic. He diagnosed the problem in less than 5 minutes. It's the A/C compressor clutch. It locks up at slow speeds, but will grudgingly spin with higher rpm's. So, it off to the shop Thursday for the fix. At least I can say it now has a new idler pulley. :)

    At least it wasn’t to expensive to get to the source. Didn’t start replacing water pumps or power steering pumps.
    Glad you are getting it fixed. Without being there or having a video of the noise it’s hard to diagnose over the internet.

    @OR17TRD, I understand completely my friend, and I do thank you for your help and suggestions. I was standing right there, and couldn't definitely diagnose it myself. With the A/C working, and cold I would have never thought to look there for the problem. The idler pulley was cheap enough to replace, and the old one had some side to side play in it anyway. So, that's good to go now for sure. As a member said here, we are basically daily driving a rolling museum, and everyday is an adventure. :)

    OK folks, here's an update on the update. Even though the A/C compressor clutch was bad that wasn't what was causing the squeal as we thought. It was the water pump. The mechanic said he had never seen a water pump that did that when it warmed up, and I haven't either. So, my little Yota now has a new A/C compressor, water pump, drive belts, and radiator fluid. And, it's quiet as a church mouse. I'm happy, happy, happy. It was quite embarrassing when stopped at a stop light. You could hear that thing 2 blocks away. :)
