420A 420a Alternator top tensioner bolt

[Sleepy2L]

So today as I was going to remove my alternator on my 99 Eclipse GS I noticed the alternator looked fairly new, upon further inspection the top tensioner bolt on the top of the alternator is completely missing. Do you guys know where I can get a bolt at/ what kind of bolt. I know it’s a 15mm. I will include a picture of the bolt I am talking about

Is that smaller bolt the one that faces the firewall?

The other one I am talking about is the one that faces the firewall, it’s a 13mm. I believe you unscrew it to relieve the tension off of the belt. What size is that one also? Sorry haha I don’t mean to make you disassemble yo car

The short bolt (part # 06504880aa) goes in the slot on the side of the upper alternator mount bracket and then thru the upper hole on alternator housing. It has a nut that goes on the end.

After you loosen the nut on the bottom mount, you loosen the nut on the short bolt and then turn the long bolt to adjust tension.

The long bolt threads thru the end of the short bolt. The head will be toward the firewall.

In the picture the bottom would be the firewall side, the top is the engine side.
If that doesn't make sense I can go reinstall it and take a picture from whatever angle you want.

The engine is on a stand so its not a problem

That would be nice, if you didn’t mind. I am missing that short bolt and the long bolt entirely. I think I’m gonna go to the hardware store tomorrow and purchase the 90mm bolt and grab a nut to hold the alternator in place hopefully if I get them tight enough the tension will hold

That’s what I get buying someone else’s project car…

I think I might have one of them laying around in my toolbox. I'll check and see if I can find it when I get off of work. If I do, you can have it. I don't need it .

Let me know if you were able to find it

I tore apart my tool box, couldn't find it.. but if I run across it I will let you know. Maybe @dacowgod might have some?? You could also message miller import parts at https://www.facebook.com/millerimportparts/

I'm changing my alternator belt today, my long bolt that goes in the shorter bolt is gone as well. The tensioner for the power steering is reverse threads, is this bolt reverse threads as well?

It doesn't look like it. From the picture it looks like you turn both the lower bolt and the upper nut clockwise to tighten and counter-clockwise to loosen them. Then you turn the long bolt to move the alternator out or in to adjust the belt tension.

Actually it is reverse thread.

The Alternator adjuster?

The Alternator adjuster?

Nope. You're right. As you can see I thought we were referring to the other accessory belt. That's the problem with staying up so late.

I hear you, I'm exhausted staying up till 12 putting that belt on and figuring it out

Been there, done that. Suspect it might be a bit of confusion so I asked, but it's always possible that I'm having another senior moment.
