What grade of Loctite for bolts

The service information will normally call out any types used and where. 99 percent of the time it will be nothing stronger than the medium strength blue 242 as the high strength red versions require heat to break them free. There are a few places to use the red but they are only in places where you are not commonly going to be removing them again as they require heat to break them free. For the flywheel the new replacement bolts will likely have anything needed on them from the factory.

Thank you so much Sir.

You're Welcome.
