Water pump pulley noise A mechanic I know says it sounds like the water pump, but I don’t see any leak and have my doubts since the car isn’t that old. THIS IS T How I quickly and effectively can spin the water pump pulley by hand. Started getting a 2nd noise (sounded like lifter clatter) and this How To Check For Shaft Failure First, check the “water pump shaft” and pulley, for signs of damage or movement. Once you hear the noises, you have no time left to waste. It's not belt squeal, it sounds like a pulley bearing is dying. The car has 105K (miles) on the clock - no paperwork to suggest a timing belt change, other than a handwritten note in the back of the handbook to say it was done at 77K (miles). An a/c car would have a double pulley on the power steering and an addition belt from the a/c, power steering, crank pulley. This problem is usually caused by a worn-out shaft bearing. I have found the source to be a very slightly wobbly pulley. After you remove the serpentine drive belt, rotate by hand the engine coolant pump pulley as well as the idler pulley, to see which feels "rough". ltojwwhwvqrrargimrkeeggtifkzhhqbrokcwaftgfzzjfwwiycmsjjjselsiblnjoxbgxamdxegqf
