    Does anyone recognize this squeaking noise coming from the engine bay? The sound only occurs once the car is fully warmed up and the frequency of the squeak seems to increase with RPMs. The drive belt, tensioner pulley, and two other pulleys at the front of the engine are brand new. No leaks or issues with drivability.

    Wait ten minutes in idle and see if noise changes
    If so it can be TO bearing

    I haven't heard this on my 430 in 5 years and 25k miles, but I if I were to guess based on other cars I've owned, that sounds like a water pump.

    I appreciate the suggestions. Given the age of these cars it probably doesn't matter much, but the car has a little under 11k miles.

    @flash32 if the noise is still there after 10 minutes of idling does that increase the likelihood of it being the TOB? It's an F1 car and my understanding with these is that there is no way to release the pressure plate from the TOB to really pinpoint it like you could by having a clutch pedal.

    I just changed the engine oil a couple weeks ago and didn't observe any oil or coolant seepage around the oil/water pump area.

    That is the reason behind the 10 mins ..after ten minutes of idling in neutral without touching anything the plate will be released..hence the same test as a manual car

    Does the noise go away if you put the car in first

    Don't think its the issue, but a simple test for the belts....spray some water on the belt while it's running. If the noise goes away, it likely is belt/tensioner related. If it didn't squeak before the new belts and did soon after, i'd suspect something to do with them or the install. I've seen plenty of new items be wrong/defective/installed wrong.

    Noise is unchanged if the car is in 1st and I could hear it while moving along in 1st as well. I haven't had a chance to try flash32's neutral test yet.

    The squeaking was present before the new belt/tensioners. I figured since I was going to have the undertray off anyways to change the oil those were cheap enough items to replace while I was there since my initial thought was a worn belt/pulley. Unfortunately, those didn't make a difference. I spun the A/C compressor pulley and alternator pulley by hand while I had the belt off and there was no noise or play coming from those.

    Also consider buying a mechanic stethoscope and narrow down area /pin point it

    Well, it's been a couple weeks now and the squeaking noise hasn't returned since I took the video (go figure). Maybe the new belts/tensioners really did fix the issue and it just took more than one initial drive for everything to settle in? No clue, but I'm not complaining!

    If the squeaking returns, then I will report back and share my findings.
