I have 3 kinds

Red loctite #242
Blue Permatex loctite "MEDIUM STRENGTH"
Loctite 425 instant adhesive

which one should i use on the flywheel 12 point 17mm bolts i dont want them comming out?

and which if any on the pressure plate bolts?

 

i use blue on mine

 

Never dealt with it on car parts, but red is t3h evil!!! Go with the blue.

 

well if I remember right, red is permanent, blue is just to hold it in but can be taken out, dont remember what the last one is for.

 

ive never used it on flywheels either. but yea stay away from red.
