My father's LS400 has eaten a serpentine belt due to one of the pulley's seizing up. It's the one right above the water pump, a groved pully that doesn't seem to serve any function other than for belt routing (just a threaded bolt holding it on). The bearings on it are toast, so the belt just shredded against it right as he pulled in the driveway.

Can anyone get me a PN for replacement? Or, does this pully also exist on any of the 2JZ motors? If so I'll yank one off my spares.

Thanks!

 

What year LS400? You forgot to mention that.

 

i think its a 90 based on his sig.
