Anti-seize on engine mount brackets?
I am getting ready to replace my engine mount and I am wondering if I should use anti-seize on the bolts that attach the mount to the engine and chassis. Most of the write-ups mention using loctite on the bolts connecting the bushing to the chassis bracket, but don’t state if you should do anything special with the other bolts. Since just about everything seizes up under this car, I thought maybe some anti-seize would be a good idea.
Any thoughts?

It never hurts to use anti seize on fasteners, particularly where steel meets alloys.........

To seize, or anti-seize, that is the question…
Consider: when you have worked on a car last worked on by someone else long ago, did you wish that mechanic had applied an antiseize treatment, or a thread-locking treatment?

Always! I was just worried it might not hold as well with all the vibration from the engine. But I suppose that's not an issue if it's approved for things like suspension.
I will go forth and anti-sieze.

If the fasteners are torqued to spec, they will not come loose.............

JFP: but don't you need to reduce the torque spec by 10% with anti-seize?
