Using loctite on a taz5 E3D hotend

My TAZ 5 has an e3d hotend. Everytime I change the nozzle, the heat block comes loose from the thermal tube. I was wondering if adding some heat resistant loctite to keep the heat block from coming loose would work. Would this cause any issues?

The old V2 Hexagon Hot Ends used to use locktite, so it’s reasonable. However, the Volcano Hot Ends on the V3 Dual Extruder do not. I would check the assembly instructions on E3D’s website. You can start your search here: https://e3d-online.dozuki.com/

This is normal on V6 style hotends. The nozzle tightens against the heat brake. That holds the heater block in place when the hotend is assembled. Just make sure the heat brake is tight in the heatsink.
