BILLS04SS Posted January 21, 2009 Report Share Posted January 21, 2009 I bought a new 145 amp alternator and got the correct belt for this setup. Does anyone know if it is just a plug and play setup?? Using the existing bracket.. etc..?? Thanks in advance. I hope this in the correct section.

misterp Posted January 21, 2009 Report Share Posted January 21, 2009 Yup, plug and play. There was a change at some point where GM changed the electrical plug on the alternator (!) but as long as the plug fits the only other issue that is a possible concern is the change in belt length (we found a TBSS belt fit ok). But physically the alternator case mounts are the same, they bolt into the existing power steering bracket with your existing hardware. A very worthwhile upgrade. Mr. P.

sonickoolten Posted January 21, 2009 Report Share Posted January 21, 2009 is ther anything biggger than 145? Quote Link to comment Share on other sites More sharing options...
Hankg42 Posted January 21, 2009 Report Share Posted January 21, 2009 is ther anything biggger than 145? GM Parts Direct lists a 160 amp alternator for our trucks, and some have also upgraded to 200 amp. Both of those probably would need other upgrades to support them, such as what Krambo told me... "fusing the main power lead off the back of it since the stock fuseable link may melt under heavy demand". I'm not enough of an electrical whiz to elaborate on that or other requirements of a larger alternator than a 145 amp. Quote Link to comment Share on other sites More sharing options...

detjoe Posted January 22, 2009 Report Share Posted January 22, 2009 The newer alt have different plugs than my 03. I heard you could get a adapter plug but have not seen it or heard where to get it from. I have a 145 sitting on the shelf b/c of this Quote Link to comment Share on other sites More sharing options...

zippy Posted January 22, 2009 Report Share Posted January 22, 2009 I've put a few of the larger alternators on SSS's. Even on the 03's they should be a direct bolt on if you get the right one just so long as you have the longer belt. Quote Link to comment Share on other sites More sharing options...
detjoe Posted January 22, 2009 Report Share Posted January 22, 2009 I got the alt from my L92 donor...so I am guessing an Escaladew ould have the 145 but it has the newer plug. If I went to napa what part am I asking for? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 22, 2009 Report Share Posted January 22, 2009 what do we got in our trucks? AWD w/clutch fan - 105 amp RWD w/factory e-fans - 145 amp Quote Link to comment Share on other sites More sharing options...
BILLS04SS Posted January 22, 2009 Author Report Share Posted January 22, 2009 Thanks everyone for your feedback.. I'll be doing this upgrade this weekend Will post some pics Quote Link to comment Share on other sites More sharing options...
SSThunder Posted January 22, 2009 Report Share Posted January 22, 2009 easy upgrade. I got my 145 amp off ebay and it was a direct plug-n-play. I've got a radix so I did order a different belt but so far the belt I was running still fits, just a lot tighter. Quote Link to comment Share on other sites More sharing options...
