    PLEASE HELP: Strange Engine Noise in 2017 Dodge Charger R/T

    Please help me identify this noise. The car has about 37,000 miles on it. The noise changes with engine speed. Spraying WD40 on belt does not change sound. All residue seen on engine is WD40. I'm trying to save myself some diagnostic work here. So if you've seen this before, please let me know what you found out. Thanks so much for your help.

    This is a easy one - Im a dodge tech. This is a bad water pump bearing- make a froggy sound. They have extended water pump on some late models. Have dealer check.

    Is the A/C or defrost on? if it is try turning it off, it might be the compressor clutch cycling on/off and chattering? you can also try removing your accessory belt, then start the car and see if the sound went away,only run it for few minutes as the water pump will not be spinning and neither will the alternator, might also be a bad idler pulley too. do you have a really long screwdriver or mech stethoscope to touch to some things and diagnose further?

    Never spray WD40 on a belt as it drys them out rather quickly.
