My 1999 Mazda 626 4cyl 130K miles, broke the serpentine belt for the Alt and WtrPmp at 125K. No squealling no nothing, just broke from mileage and wear (?). I replaced both belts due to the high mileage and "Murphy's Law of Auto Reapirs". Cost $40 and 2 hours of my time. About 3 weeks later the squeal is back. I can't identify and idler pulley in this blet path - Alt/WtrPmp/Main Pulley - so I tighten the belt slightly. No help, squeal continues periodicaly until the belt breaks again after about 45 days and 4K miles. Fearing workmanship issues (Me) I had the dealership do it the 2nd time. Both belts again, $213. Now after just 3 wks I'm back to square 1. I took it back, told them it is squealiing. They adjusted the belt slightly cleaned the pulleys (belt crud, imagine that?). They said everything looks fine. No mention of Idler/Tension Pulley. They didn't seem to have any issues with Alt or Water Pump. Alt makes no bearing noise, Water pump makes no noise. But I still have the squeal problem intermittent on start up and pulling away from a stop once in a while. Any thoughts? IS there an Idler Pulley in the Alt /WtrPmp belt line?
have the same problem?
