    I've been curious and somewhat confused about when and where to use anti-sieze and dielectric grease. I know that anti-sieze makes it easier to take parts apart but are there places that you shouldn't use it (i.e. lug nuts, exhaust manifold bolts)? If you torque the fastener down to the proper setting is there any chance it will back out since it has less friction?
    Same with dielectric grease, on what electrical connections should it not be used? I know makes a better electrical connection and helps prevent corrosion due to dissimilar metals, but what about high current situations like on battery posts? Or shouldn't I worry about it and put it on all my electrical connections whenever I make a repair.

    antisieze=on brake drum adjusters, things that need to be kept from rusting together, also use between the back of the wheel and the hub/drum
    dieletric grease=use whenever possible on electrical connections, not too much though, also use on drum backing plate bosses where the shoes ride, also on the caliper slides

    dielectric grease is for all electric connections, plugs, surfaces, spark pluig wires ends, underneath ignition modules, etc. and so forth

    dielectric grease is not for brakes lol

    i always use chassis grease for shoes to slid eon backing plates, dielectric grease costs more and is a waste to use for anything other than what its meant for- electric connections!

    Anti-seize should be used anytime you thread a steel fastner into aluminum, i.e. aluminium manifold thermostat housing bolts, distributor hold down bolt, egr valve, carb mount bolts, anything that mounts to aluminum that uses a steel bolt. All to many times I have seen someone ruin a good aluminum manifold because they did not use anti-seize on the thermostat bolts, /forums/images/graemlins/doah.gif and end up shearing them off trying to replace the thermostat. /forums/images/graemlins/deal.gif /forums/images/graemlins/thumb.gif
