Thread: Will this alternator fit my 02 gp gt?

I don't think it will...

I thought those were clutch'd alternators and the 97-03's weren't...

Not sure.

All I know is you can get a 99-03 Alternator off of any WBody and it should fit.

Well I just bought one from rock auto.


I should have it in a few days and will let everyone know if it works or not. Pure2sin looked into it and thinks it should work fine.

I sure hope it does !

I just looked at the pictures that were provided on rock auto and it appears that the plugs might be different?


The plug looks like the same shape/size but mounts differently in the alternator. Does anyone know if the wires or plug is different between the an 02 impala alternator and a 02 gp alternator?

Well its confirmed. You can use a 125 amp alternator from the 00-05 police impala's in a 02 gp gt. It matched up perfectly. Wiring harness is in a different spot, and so is the power wire but it still works.

The only problem is, it didn't solve my problem......


Thought I would let everyone know though in case you wanted to upgrade to a larger amp alternator and didn't want to spend a ton of money. I got this one off of rockauto for like 140 bucks.

Oh and I wanna thank Pure2sin for helping me. He did some research and told me it would fit when others said it wouldn't. He was right....
