    So I don't get a lot of "cold" weather out here but during the cooler months I've began to notice a chirp like squeak. My investigation keeps me coming back to the area of my PS pump. I would say it happens below 50 degrees or so and it definitely gets worse the colder it gets.

    Last weekend I broke out the ol' turkey baster and a couple feet of tubing and flushed the entire system with Dexron 2 just like @FirstGenVol did a while back. The fluid was dark black and had little viscosity so I assumed I was onto something, but alas, the chirp returned today.

    Ive pulled my serp and tried freehanding the pump but cant quite get it to 1k rpm to replicate the chirp. :muscleflexing: Honestly I'm not entirely sure that its coming from the pump but don't know where else it would be.

    I figured I would poke around in you guys' heads before ordering a new pump. Maybe someone else has had this same thing happen and you might have a different approach than what Ive taken.

    Truck has about 170k on it and from my guess, the pump looks to be OEM.

    Ill see if I can get a video of it some time soon and if I do Ill post it up.

    Try a psf flush. I just did one with Oem fluid. No issues.

    Did you only turkey baste it once? I had to do mine 3-4 times over a week or two before all the old fluid was out. What ATF did you go with?

    I have a vacuum pump do I vacuumed the reservoir then disconnected the lines added two qts of psf to container and cranked the engine till al fluid is changed. Reconnected the lines. All is well

    I used the techniques this dude used and ran almost two full quarts through it until it was obvious I was pumping out new, clear, red atf.

    I just used generic Vatozone Dexron 2.

    That's the video I used also. If that didn't do it then maybe the noise you're hearing is something else?

    I mean it’s highly unlikely it’s the alternator right? The only other thing on that side is the tensioner. Also neither one of those really explain why it only happens when the outside temp is cold right?

    I'm honestly not sure Josh. Cold can do weird things. But the tensioner seems a lot more likely than the alternator. They are very close to one another so I can see what you mean. You have to unbolt the alternator the replace the tensioner.

    Was yours doing the same thing before the flush?

    I seriously wish it would get cold again so I could record it. The squeak isn’t your typical serp belt squeal or squeak. It’s more of a chatter like a styrofoam cup on a country road.

    No mine wasn't making any noise
    The only time my power steering pump ever makes any noises is when I hit full lock on the steering wheel which is normal. I view that as a reminder to back off. Take a video next time if you can.

    No man I like swapping fluids out soon brake,tranny,power steering etc. I’ve heard a lot of people using atf. I’m had purchased two qts of Asian psf already.

    Here is what I got this morning. This is minimal compared to what it has been over the last few weeks. It varies with rpm and doesn’t necessarily stop when the truck gets warm.

    I'm far from an expert but that sounds a lot more like a pulley to me. Maybe a belt.

    That is a belt problem

    I'd get a can of belt conditioner/dressing. And the next cold morning, start the engine, with the hood up, and spray a small amount of conditioner on the power steering pulley. See if it changes the sound. CRC belt conditioner specifically says it's not for serpentine belts, so don't dowse the thing like you would a V-belt -- just a little spritz. If the sound changes, you've found the source.

    That sounds EXACTLY like the noise I had on my 2005 Tundra's serpentine belt. I could put belt dressing on and it would go away for awhile and then come back. Turned out to be a little corrosion on one of the pulleys was causing it to squeak. Ultimately just took a little sandpaper to the groove of the pulley and it never came back.

    When I swapped in a new ‘accessory belt’, aka ‘v-belt’, I inspected the pulleys. Two of the pulleys had rubber knobbies built up on them from years of use and prior slipping thus leaving residue behind.

    I carefully rotated and scraped, using a razor blade, the rubber build up off the smooth metal pulley surface contact area. Lightly cleaned the smooth metal with brake cleaner and reinstalled the belt.

    I did have prior ‘squeal’ but not ‘chirp’ noises. Quiet now.

    There's only one liquid fix, BEER. :cheers: Take the belt off and just check all that spins. Most of the times it will be the belt, or if anything the tensioner and idler pulleys. I take mine apart and just re grease. I now use the heavy duty green belt. Much better.

    Pulled the belt yesterday and everything spun freely with no noise. There was no buildup on any of the pulleys either. The belt is maybe a little over a year old but I think it was an autozone cheapo.

    I ordered a green belt that should be here tomorrow so I’ll see if maybe it was just a bad belt.

    I’m still unsure where the squeak was coming from but it does seem as if the green belt fixed it.

    My only thought is maybe it was the smooth pulley behind the fan clutch. When I was removing it, it seemed that the pulley slipped in the belt a little too easily.

    I must say, the green belt appears to be far and above better quality than the cheapo Dayco. The green portion seems to be some kind of softer, grippier rubber. We’ll see how this works out.

    I got a like on some post and it reminded me to update.

    Surprise: Green belt fixed it and I haven’t had a single chirp since.

    Many thanks for this thread! I have a similar squeal in cold weather which occurs on initial start only. Mechanic wasn't sure if it was the belt or the tensioner...I think next time I will have him change the belt (he only uses OEM) and make sure the pulleys are clean.

    Thanks for this thread gentlemen, I just started having this exact same issue over the last couple cold/rainy days. Sounds like its coming from the PS pump area but I checked all the pulleys and all spin freely with no bearing noise, I am going to replace the belt and clean all the pulleys tomorrow!

    My truck has been like that for the past 70k miles. I’m guessing my issue is one of the bearings in the the PS pump. It typically goes away after the truck has been running for a while. Initially it was only in the first few minutes of running it cold. Now it can last quite a while.

    Edit: Oops, I guess your issue was different than mine. I didn't see your fix.

    Green belt is still holding up. Even with the week of sub freezing temps we had.

    No doubt in my mind that it was a worthy purchase.

    I have this same issue, I replaced the belt with a green belt and replaced the tensioner pulley also. The noise went away for a week but came back. Only has the noise during cold starts in the morning and lasts for about 2 seconds max. When I turn the when the noise lasts longer. Going to check the pump this weekend.

    Check that there is no residual rubber chunks on the smooth idler pulley. I had to hit mine with some rubbing alcohol. Which is honestly, probably not a bad idea anyways.
