Hey gang.
My 18 year old son was driving my 2000 100-series (his Isuzu VehiCROSS is temporarily down for issues of its own) when he said it stalled in traffic. He restarted it and moved to a parking lot but didn’t feel comfortable driving it home. (He’s only been driving for about a year and it’s really mechanically inclined and he didn’t want to risk further problems on the way home.)
So I drove over to where he was and had him start the engine. I noticed a noise coming from the serpentine belt area that I’ve never experienced before and I can’t quite identify. Although the sound was unusual it didn’t seem calamitous, so I drove the Cruiser home about 5 miles from where it first stalled out. There was nothing off about how the truck drove—power seemed normal and there were no drivetrain vibrations—but if I turned the radio down I could still faintly make out the rattling from the engine area. Gauges read fine and my onboard OBD2 reader didn’t pick up any codes or abnormal sensor readings. However, when I got home after this 5 mile drive and popped the hood again to listen for the sound, the truck did stall again the moment that I closed the hood. This all has me kind of stumped.
For background, I did have the timing belt, the serpentine belt and the idler pulley replaced (at a Firestone Complete Care, I was out of town and desperate) about 6 months ago after the serpentine belt grenaded itself and locked up around the pulley (or vice versa). I haven’t had any problems with any of the belt-driven accessories since that time but if there’s any one thing that I can tell might be a little visually off it would have to be that the fan pulley/fan clutch assembly seems to maybe be a little off balance. But would that make this kind of noise?
Any ideas or suggestions would be greatly appreciated. I’m out of work at the moment and don’t have a lot of extra money for a mechanic to do exploratory surgery, but if someone had an idea of what I should check I’m handy enough to fix it myself. I’m just not great with the diagnostic part.
