Can anyone tell me if a geo metro's alternator will work on a sami?I know the pully is different but could that be changed out?Trying to get a cheap fix till I can do the conversion for the CS130 105amp.Mine is squealing bad,im asuming the bearings are out althought its charging fine.I can pick up a metro alternator for 15 bucks at our pull a part so I was wondering if that could be done??

it fits the sunrunner which is the same as the geo tracker and the 1st gen suzuki sidekick as well as the firefly, sprint, and swift. I think the only difference you'll see is the pulley and possibly the electrical connector. The pully you can take off with an impact wrench and a gear puller, the one on your samurai should fit right on the shaft of the pick and pull alternator. When you get a CS130, the shaft is wider and the pulley will not interchange you will need to get a v-belt pulley specifically for the GM alternator.

The Metro alternator should bolt right up in place of the Samurai one, and with the pulley changed it should work - but - those are really low output alternators 35A or something along those lines, so bear that in mind.

And if the Metro has the 1.3L and still has the aluminum valve cover, you might want to get it also. I got mine there for $12.

Isn't the stock Samurai alt 35 amps?

the metro alts are 50-55 amps. Samurai has a 50-55 amp alt.

If you have a squeel after changing the valve cover, check and make sure your belt isn't slipping. You may have gotten some oil on it or something and even though it still turns the alt, it may have a slight slip under load causing a chirping or squeeling.

Yea that was the 1st thing I thought of so I steamed my engine to get all the gunk off plus to see if I had any more leaks around my valve cover.I took off my belt and truned my alternator by hand and sure enough its real rough and kinda grinding.BUT,the good news to all of this is yesterday I went home and went thru my filing cabinet and there I found my receipt for the last alternator I put on in 06' which had a lifetime replacement!!So today after work Im going to get me a new one.Even a blind squirrel finds a nut every now and then!!lol

That might depend on the Metro - but as far as I know the Metro has a 35A alternator, the Swift has a 55A, and I have no idea what the Samurai has, although I suspect it may vary with the year - as carburetted engines required less power than EFI.

According to the FSM, the '87 had a max output of 45amps.

The 90-94 supplement says it is 50Amps. It also mentioned that the structure and operation was the same as the '88 model.

definitely. The G10 metro's with the 1 liter 3 cylinder engines had a much smaller alternator. The G13 metro's with the 1.3 liter 4 cylinder engines had the same alternator as the samurai. The samurai alternators are rated at 45 amps from the factory, but most rebuilt ones that you find usually rate them at 50-55 amps. I guess they figured that it would be silly to de-tune the rebuilt alternators from the later applications that used the same case as the samurai. Some people upgrade to the rebuilts or drop in a tracker/sidekick alternator for that extra 5-10 amps.

Awesome that you found your reciept... I never keep those things.
