Your belt could be glazed or there could be grease or oil on the pulleys. Make sure everything is clean and dry. Having the belt too tight can result in bearing noise from the alternator, but that is usually continuous regardless of electrical load.
What year is your Supra?...The alternator bolted right up, no problems at all!! The belt was a bit tricky though.
Will 160amp alternator be fine to use with the stock wiring?i just recently put a 160 AMP mk-III upgraded alternator on my 6m. (Mah huge stereo was killing my electrical system) it is much much happier now. bolted right on there. had to convert to the round plug and i had to drill out my old pully to make it fit the new alt. easy swap for MORE POWER!!!!!
Yeah good luck with that LOL!Will 160amp alternator be fine to use with the stock wiring?
Love the response, but most of these guys don't have engineering degrees and may not see your sarcasm. I^2*R heat loss? Good bye fusible links.Yeah good luck with that LOL!
Excellent information. This makes me feel better about the 80A alternator waiting to be installed on my daily driver. Thank you!I^2*R heat loss? Good bye fusible links. Your car was designed for a 60 amp alternator, meaning at most 2x that (120 amps @ 12 V) assuming everything is at design spec.
Any more info than this on the +93 Camry alt? I already have an 83 that has the harness converted to the 85 style plug, and I'm running an 85 stock alt on a 6m, so adapting the harness to the +93 can't be that big of a deal, and provides another option. Also, of the alternators mentioned in this thread, none are more available to source used than a +93 Camry. If all I would have to do is convert the harness to connect to the +93 alt, and use a 6 rib escort belt, I'm thinking that may be the way for me to go.From: The alt is from a 1992 Camry v6 3VZFE (Round Plug). 93+ alts will not work because of plug design (though you can modify the wiring harness)
Slice a rib off of your stock belt, bro. I did it and it worked fine.I picked up the 80 amp alt and went with the 1990 Ford Escort belt...no way that was going on the car...way too short! Then I went with the AC belt (for factory installed AC, but not dealer installed) 1987 Mustang 4 cyl will also work...way too long to even be tount against the 3 pulleys. Then I went with the Camry belt...also way too long. WTF?!? Are there any other options for a belt or am I just going to have to use a 17mm drill bit and go to work? Maybe my friends at Advance Auto Parts got the parts incorrect...not sure.
I took the liberty of quoting a few old posts from this thread. I hope the information is useful!I picked up the 80 amp alt and went with the 1990 Ford Escort belt...no way that was going on the car...way too short! Then I went with the AC belt (for factory installed AC, but not dealer installed) 1987 Mustang 4 cyl will also work...way too long to even be tount against the 3 pulleys.

This is from the first post
[The Camry alt] is from a 1992 Camry v6 3VZFE (Round Plug). 93+ alts will not work because of plug design (though you can modify the wiring harness).
Tell the dealer you want an alternator form a 1992 Camry V6 3VZFE and you should get the correct alternator. I believe 91 alts are different.
I had a fitment issue with the Ford Escort belt and did some research. The stock MK2 alternator uses a 7-rib 36.2" long belt. The 1992 Toyota Camry V6 uses a 6-rib 37" long belt. The pulleys are virtually the same diameter, so I'm going to try the 37" long Camry belt and see how that works out. Will be nice to be able to say you need an alternator and belt for the same car when buying these parts!!!
Will post my results when I complete the project.
OK, I just completed this upgrade and would like to offer my :twocents: for people who do this in the future and don't want to swap out the alternator pulleys...
When you buy your new 1992 Camry alternator, just get the belt that goes with it! The original '84-'86 Supra uses a 7-rib 36.2" long belt. The '92 Camry V6 uses a 6-rib 37" long belt. The adjustment may be close to being all the way extended, but there was still a little bit of room at the end of mine when I got it tight enough. Everything else was plug-n-play.
EDIT: FYI - The 1991 Camry came with a 2.5L V6 and the alternator is only 70 amps. The belt for the '91 Camry is also a different length.
Which Camry belt did you get?! The one for the '91 or the '92 Camry?! The '91 Camry belt is 41" long!!Using the '92 Camry belt on my '86 w/ the 6M worked nearly perfect! It shouldn't matter whether you have a 5M or 6M when doing this upgrade. All the accessories are identical.
Perfect! Thanks for the solution...worked great. Hope it lasts...but so much easier than the belt search.Slice a rib off of your stock belt, bro. I did it and it worked fine.
