The reason I am asking you all this question because I am getting alternator belt slip every time I start engine. The 5vz-fe came with 3 grooves crankshaft. The alternator is too strong for 3 grooves pulley on the alternator. My alternator is a 270amps. It's for my stereo system that keep my electrical system strong. The 270amps alternator came with 5 grooves pulley but I changed it with stock 3 grooves pulley. The alt belt is new and tight. It has been like this ever since I installed a new alternator. I always ignored it. It's getting on my nerve now.

I might don't get much help from here but I give it a shot.

maybe try a different brand of belt?

Yeah someone suggested me about the gates belt.

gates or a GoodYear gaterback if they make them for the 5vz. I would try that route first since it's the cheapest.

URD makes a "supergrip" pulley... not 5 rib tho. just sayin

Thanks for telling me about URD but dam to expensive $99.00. They also make crankshaft but is $299.00. Forget it.

I'm gonna try belt first.

have you tried a stock yota belt? i actually have had bad luck with the two belt's sugested at less then 100amp on supra 3rib set up's.


oh btw what altenator are you running to achive 270amp's?

the only one i knew about was the mr2 100amp eletric power steering model.. as far as stock altenators go..

I think I threw away the old one.

There are few companies that can make 200-300 amps alternator(i've seen upward to 400amps). Look up Iraggi Alternators, DC Power Engineering, Mechman, Ohio Gen, and Powermasters.

I know they make the gatorback belt for it. Been running one for about 3 or 4 years now.
