Name that chirp

Replaced water pump and both idler pulleys. Still constant chirping at 2k+ rpm. Won't do it cold but will when warmed up. Any ideas?

Could be some coolant in the alternator, just needs to dry out...Or a bad tensioner...Get yourself a mechanics stethascope and check around the engine compartment.

All you really need is a long screw driver or long dowel rod. Put one end to your ear and the other on the part you are listening to. You will easily tell where it's coming from.

My vote is on the belt . Try spraying a little water on the belt to test it while warmed up and running when making the noise

Thanks for the help. Used a mech stethoscope and it's the alternator making the noise. The pulley gets super hot too after idling for only a few minutes.

Mine had the same noise and i change the idle pulley, that stops the noise at the begining, after 2 weeks the sound came again and i had to change the harmonic balancer, that solution the problem definetely.
