Stupid problem, the alternator tensioner is flat out seized, the bolt is rusted beyond hope of recovery.

I am totally failing to find the part number for it on any toyota site. Anyone got any idea of what it is before I drag the actual rusty bolt to a dealer?

Rummaging through my scattered Excel files since my computer crashed for part #s, I think it is # 90119-08493. Only about 90% sure. It lists for $2.10 but good luck getting that price.

Thanks! That number let me find this post:

IF YOU BROKE YOUR ALTERNATOR TENSIONER BOLTS IN ANY WAY, HERE ARE THE TOYOTA PART NUMBERS:

90119-08493 = Long tensioner Bolt

16385-62020 = Short Stud that goes through the alternator, with threaded hole for long bolt

Nice work. The reason it is so hard to find is that TOYOTA has listed these parts in the "RADIATOR & WATER OUTLET," category, and not somewhere sensible like "Alternator". I looked and couldn't find them for this reason (until I actually HAD the number.).

Both the diagram and the description give you no clue that those parts go to the alternator. I bet more than a few parts counter guys would get stumped on this one.

Thanks for this - my dealership parts guy couldn't find it either, so I searched the forum while on hold and popped right up. He said "how the hell did you find that?"

My bolt was rusted and snapped off while loosening. I had to apply some heat to get the rest of the bolt out of the studded block that it screws into, the I ended up getting a bolt from the hardware store to replace the broken one because I didn't have a day to wait for Toyota.

If anyone needs it, it is M8x1.25 and 80-90mm long. I think I used the 80.

I just wanted to thank everyone who contributed here. I just got back from the dealership and they couldn’t find it. Now I at least have the part numbers for the bolts. Does anyone have the part number for the block that the bolts go into? I have kind of a bush fix that’s holding for now but it’d be a load off my mind to get the actual part. No pick and pulls around here these days
