    I just replaced my harmonic balancer on my 6.2. I know I need to torque the bolt to 200FT/LB but do I need to use any thread lock or anti sieze?

    I would...

    I dont know if its reccomended,but I would but some threadlocker on the bolt threads,being a diesel they like to vibrate everything loose--but dont use the killer "green" locktite if you ever want to get the bolt off again!--and I wouldnt put any on the crankshaft or the dampers I.D.--its ok to do it on a small block that has no bolt(or one that has a broken bolt in the crank!),but I dont think its nessasary--I could be wrong though!---and 200 ft lbs?? that sounds like a lot of torque for a bolt that size!--are you sure thats the right spec??:confused:

    Got this from the tread:

    140-162 ft. lbs on 82-84 models, and 200 ft. lbs on 85 and newer models. I'm not sure why the different specs. I don't think there's any difference in the parts between these years, but I think that GM decided to make that bolt tighter in 85. So I believe that 200 ft. lbs is the recommended spec for all engines now.
