Re: UIM torque specs for 2002 with 3800 motor
Are you using the stock GM UIM or an aftermarket like Dorman or APN?
Originally 89-in-lb for the UIM Plenum, however, GM revised that to 132 in-lb around 2003 in a tech bulletin. The LIM bolt torque is 11 lb-ft so that matches 132 in-lb. But to be safe go with 89 in-lb in the proper pattern which is what I use.
