How to replace the engine mount on GMC C3500?

Before replacing the engine mount, first make sure the engine is well supported by a jack that doesn't place any weight on the mount. Raise the engine just a little so that removing the engine mount won't make the distributor contact the dash panel. If you are replacing just the front mounting, take off both because straining one can lead to additional stress. Unscrew and remove the through-bolt and nut from the engine mounting, then take out all the bolts, nuts and washers for the mounting assembly and lastly remove the mounting assembly. Position the mounting assembly in place, fasten it with the bolts, nuts and washers and tighten the bolts to 59 Nm (44 ft. lbs.) and the nuts to 45 Nm (33 ft. lbs.). After that, insert the through-bolt and nut for the engine mount and slid the engine down until the bolt is lined up to the hole. Then tighten the nut to 68 Nm (50 ft. lbs.).
