    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
