Torque Specs

Welcome to my 2004-2006 Pontiac GTO Torque Specifications guide. It is extremely important when working on your vehicle to tighten any nuts and bolts to the proper Torque specification. Over tightening can put stress on the bolts and cause them to break or snap. Under tightening can cause nuts and bolts to come loose, causing serious problems to parts on the vehicle to prematurely break or fail, not to mention the dangers of driving a vehicle with loose bolts.

I highly recommend purchasing a Torque wrench for all your do-it-yourself automotive projects. You can purchase these at any Harbor Freight tool store or Home Depot hardware store. They come in 1/4″, 3/8″, and 1’2″ drive. You may need to purchase multiple torque wrenches depending on the torque settings you are trying to achieve.

Below you will find a list of common torque specs for the 2004-2006 Pontiac GTO. I will add more items as questions and requests arise. If you need a torque specification not listed, please send me a message and I will find the proper specification using the service manual.
