Does anyone know if the 105 and 145 alternators have changed in the last few years? I have a 2005 and I'm pretty sure its the same as 2004... and I've got this beligerant clown at my local alternator shop biting my head off about bringing the alternator to him before he'll give me a price. :eek: He seems to think something changed between 04 and 05 and I can't find anywhere that confirms that...

Anyone?

Thanks for the reply... can you elaborate any? Part numbers perhaps?

Basically I want to order the 2005 145amp version...

Thanks

I had my 104 changed out for the 145 when it got to the dealer. The difference is negligible except for the amperage, the belt is even the same. Will get the PN when I get home and look at the invoice.

The plugs are different on the 05 vs the 04's. 05's will interchange on 05's, but not on years.

Sorry, I missed the year change. The PN is 10464476 for the 05 145 amp alt.

River&sand... thanks for the p/n!

dmaxalliTech:
I feel like I'm being a pain, but what are the electrical differences? Why did they change the plug... what was the reasoning/gain behind it?

Thanks
