My guess is that there was so much build up in the pulley grooves that the belt was raised up to the point where the individual vee's of the belt weren't making solid contact with the walls of the pulley grooves, resulting in slipping regardless of how tightly the belt was tensioned. So if you ever have an ungodly metal-on-metal sounding squeal from your pulleys, but the bearings on everything feel fine, examine the grooves of all the pulleys. Put everything back together, and TA-DA! - every dog in a two-block radius didn't start howling when the car fired up! Ten minutes of scraping, wire brushing and brake fluid scrubbing later, and the grooves looked clean. Pulled it, examined it closely, and found the grooves were loaded with what looked like built-up 'belt stuff'. Has anyone experienced this, or have any idea what the cause might be?ĭid a test fire with both the PS-A/C belt AND the Alt-WaterPump belt OFF, and.no howl! WTF?!?! New alternator, new water pump, new belts all around, how can this be? The only thing not new in the system was the actual pulley on the water pump. All I can think is maybe a journal bearing is spinning in it's seat intermittently? But I haven't noticed metal in the oil, as I'd expect from a seizing bearing. Short of the crank and cam bearings, I've replaced or disconnected every spinning part. But much to my dismay, the car still howled when I fired it up after installing the new water pump.

I was sure it was going to be the water pump. Mazda Protege / Protege5 2002, Timing Belt by Mitsuboshi®. replaced the timing belt and idler/tension pulleys (it was due) - no change installed a new alternator (the old one had failed) - no change - not the alternator run it with the A/C / PS belt removed - no change - not the A/C or power steering pump Once it's stopped, there's an occasional 'chirp', and that seems to be coming from down around the crank/water pump area.

When it's in full howl, it's too loud to locate more precisely than the pulley side of the engine. It's a very high pitched, shrill sound, and sounds like bearings or seizing parts.

it happens more often at low RPM, but not consistently, and rev'ing the engine while it's happening has no effect This is one of the most common problems that we face in the Mazda protege. it happens more often with the A/C on, but not consistently or continuously Idle Problem And Running Bad Under 3000 rpm. it happens at a stops more often than while under way, but it doesn't happen consistently at stops, and it sometimes happens while under way I did an extended test drive, doing laps of the same circuit, trying to find some common thread to the problem - findings. Pressed for more details, she said it happens every time she starts the car, and goes for about 3-5 minutes, then stops, but that it will sometimes happen while she's driving - mostly when she comes to a stop, and that happens more often when the A/C is on. I shut it off immediately, wondering what went wrong, when my daughter tells me 'oh, that's nothing, it's been doing that forever'. Just replaced the alternator on my daughter's '02 Protege 2.0, fired it up, and it makes this Oh-my-god-I-can-hear-it-from-a-block-away loud, shrill squeal/howl.
