I took off my exhaust manifold, turbo, turbo elbow and the other parts along with it. I am replacing my manifold with a new one. When I took everything apart, I noticed the bolts were held in with orange thread lock.

When I put everything back together, should I use thread lock or never seize?
Not in this application, but I heard that never seize was good to use with aluminum. Correct me if I'm wrong

Thanks

thread locker is usually used for non maintenance parts that rarely if ever get removed where as anti seize is the opposite (usually used for maintenance parts/parts that are more often removed than not) never heard anything in regards to metal compatibility, though

here's something cool i found when i typed in "thread locker for (and before i could finish, google suggested:) for aluminum

its a good, general read for all. it says when using loctite on an inactive metal such as aluminum that they recommend using a primer.

Never seize sounds like the way to go for avoiding binding because I have stripped aluminum threads before but I am just worried about bolts coming loose

heres another read.

after reading this it pretty much sounds like you could use either

and 'stripped aluminum threads' sounds like an over torquing problem. are you using a torque wrench and applying torque via factory specifications?

Never Seize > Thread Lock.

For the turbo elbow, you can buy crimped nuts that actually help prevent the nut from backing off. Neverseize keeps bolts from galling and/or rusting together. You're going to see extreme heat and that stuff will burn right off. Just torque them down to factory spec and you should be fine. There is also locking plates to keep the turbo nuts from backing off that you should buy too.
