Installing engine mount and accessory boltstoan aluminum block

[Joel K]

This is a newbie question. I bought anit-seize for the stainless screws and bolts which will attach into the aluminum chassis to prevent galling. My question is, considering the engine block I have is aluminum, do I need to apply anti-seize to the factory steel bolts that attach things like the engine mounts and accessories to the block.

Thanks for the help.

Joel, if you ever want to be able to remove those bolts without galling the threads, I'd suggest using a bit of anti-sieze on the fastener threads. zinc or cadmium plating helps but, over time, any corrosion or moisture in the threads will cause problems without anti-sieze. Exhaust manifold bolts are the worst offenders.

Thank you Neil, I just wan’t sure and appreciate your input.
