Posted October 7, 201113 yr I am going to be changing my Exhaust Manifold in my 99 Cummins and not sure what to torque the bolts at. I was trying to search and came up with 23, 32 and 44 so I have no idea what it should be for a 99. Any help would be appreciated. Thank You
October 8, 201113 yr Go down to the auto parts and get you a book on torque specs for your truck, you will need it in the future.The manifold torque is in a sequence. You really need it in front of you doing this.
October 8, 201113 yr Author I have been thinking about getting a book and also I did print off of a site that had the sequence, I just needed to make sure what the ft-lbs were on a 99 cummins?
October 8, 201113 yr 98-1/2 thru 02 are the same. 12 valve mybe the same also, I dont know why they would be diff.
October 8, 201113 yr Service manual calls for 32 ft/lbs. Start at the bolt at the 1 o'clock position from the turbo mount and do a clockwise pattern working outward.
October 8, 201113 yr Author I appreciate the answer, I did torque them to 32ft-lbs. Its running great. It was cracked all the way through. Turbo kicks in alot better now. Thanks everyone for info.
