I am considering a purchase of some factory tech service manuals for 03 sierra/silverado duramax. However, my truck is an 02. is there a significant difference between these two year models that might make this a wrong thing for me to do. Need some advice very soon. Thanks,http://www.dieselplace.com/forum/smileys/Big Smile.gif

Very very significant differences! Especially electrical. The 03 manuals would be pretty much useless to you as far as electrical goes. Mechanical stuff should be pretty much the same.Edited by: Max Power

Ok, Max. I really appreciate your input.
