anti-seize paste or thread locker?

[eolonano]

I have to bolt several bolts on my car (clutch and flywheel change). Is better to use an anti-seize paste or a thread locker (with anti corrosion additive) is a good solution too ?

At the moment I have just the copper paste (it's anti-seize, but is grease so no lock on the bolts) and a cfg extra-strong thread locker ( http://37.207.197.58/B2C/SchedeTecniche/Cat_Generale/Cat_Gen_123.pdf) but no idea if it has anti-corrosion action.

I have also a liquid silicone gasket (up to 340 celsius degrees) but I don't know if it is good for thread....

Any suggestion?

I'd use thread lock on the fly wheel bolts and nothing on clutch bolts

Thread locker +1.
If you buy original bolts for that purpose, there will by factory applied threadlocker on them....!

Ok, roger that.

But, for example, the bolts that join the bell housing to the engine: thread locker again or anti-seize paste ?
they are exposed to water, dirt, ecc.

do you use any anti-seize paste at all? (if yes, what kind?)
the anti-seize paste is a bit sticky to lock or it is eventually like the copper paste? (that is grease with copper).

Hi,
Don't use copper based anti-seize on bolts going into aluminium alloy castings. Copper and aluminium will corrode in contact with each other and moisture. Most replacement Fiat bolts that require locking come with an epoxy patch locking compound pre-applied. It looks like a spot of blue paint and contains microspheres of locking compound that break up and activate when the bolt is screwed in. These should not be reused. Any non locking compound bolt that has a torque setting should be installed clean and dry unless otherwise specified. Applying oil, anti-seize or liquid locking compound can lubricate the threads causing the bolt to be over torqued. A wipe of engine oil is good for other bolts if worried about corrosion.

never known them bolts to seize. suspension bolts is where you need it
