Guest Posted January 13, 2015 Report Share Posted January 13, 2015 I just got my 240amp Mechman alt for my 2003 Toyota Highlander 3.0L and it is one beefy thing. I am going to put it in first thing this weekend! So pumped! I know after doing some research I need a smaller belt. So, I went to an autoparts store and figured out what my OEM belt length was then I got a belt 2in shorter. You think this will work? Is there a better way to go about determining the optimal belt length than just plugging and chugging?? Thanks Quote Link to comment Share on other sites More sharing options...
mbdblue Posted January 13, 2015 Report Share Posted January 13, 2015 use a string....something that doesn't stretch to put around your pulleys and measure it.

Miguels Posted January 13, 2015 Report Share Posted January 13, 2015 the string thing works when you have multiple alts that really changes the belt configuration.. if its just replacing the alt try half inch to an inch shorter Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Broke_Audio_Addict Posted January 13, 2015 Report Share Posted January 13, 2015 It may be, just try it.

Guest Posted January 13, 2015 Report Share Posted January 13, 2015 Ok, I might go buy several more sizes and just return the ones I do not end up using. Quote Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted January 13, 2015 Report Share Posted January 13, 2015 (edited) Just start with the next size down from your stock belt.

Miguels Posted January 13, 2015 Report Share Posted January 13, 2015 2 inches could be way too short.. i went with 1/4 inch shorter because autozone guys could not find a half inch or inch shorter belt.. it did fit but get belt slip when high rpm and shifting gears. i went to gatorback website and looked up the sizes and the one closet was 3/4 of an inch shorter. got the partnumber and ordered from it from amazon for $8. i also ordered a new tensioner with it. which was the original ac delco for the same price that autozone sales the duralast. delco is metal the autozone one was plastic. i saved $10 ordering from amazon and getting an original part Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

There was not a half in version. Quote Link to comment Share on other sites More sharing options...
