    Looking for a little advice. Went to loosen the pan bolts and have a couple that are seized and if i twist them too hard they will snap off, i have sprayed them with penetrating oil in hopes too loosen them up but was wondering if there is anything else i can do to free them up. I drained and refilled the torque converter and would really like to change the filter. The truck only has 68k miles on it.
    Thank You

    tap lightly with a Small Hammer with the socket on the bolt use 1/4 inch it is probably seized in the aluminum case get PB Blaster might be better

    I would heat them up with a torch and let them cool completly; the different expansion rates of the dissimilar metals will help loosen the grip the aluminum has on the bolts. If you have oxy/acetylene use straight acetylene first to carbon the surface, then cut-in the oxygen and use a neuteral flame. Heat it until the carbon burns off then stop and wait for it to cool.

    If you have a turbo torch just carbon up the surface by covering the air intake on the torch body with your finger.

    If you only have a MAPP or small Prest-O-Lite kit torch then I would advise you go to a welding supply store and buy a 200 degree Tempilstik. Put a few crayon marks on the aluminum with the Tempilstik and heat until the crayon mark melts...then stop heating and let it cool.

    Good luck
