Besides the obvious...what is the difference between the two...my truck has the 105...what would i have to do to put the 145 on...i'm told the do not interchange..is this correct?
I would've thought so too, but gm-auto-parts shows a 97300653 belt for the 105A and a 97300656 for the 130A and 145A alts...Unit453;1556955; said:The belt shouldnt make any difference at all. Thats what a belt tensioner is for. It'll automatically take out the slack.
Shouldn't have a problem; it's factory w/the VYU snow plow prep...Turbotug;1558029; said:It swapped right over on my truck, used the old belt too. The housing is noticably larger, but it looks to have the same pulley placement(distance from mounting holes to pulley).
On the 6.5 (and maybe on the Duramax, I don't know) if the pulley is not the right size, your tach will be off.matuva;1657545; said:I'm willing to upgrade to a 140 or 200Amp on my 6.5. Anything special I must care about? No trouble for ECM or something else?
I bet I can just bolt on the new one, but that looks too simple...:think:
