What type of LOCTITE ?
Ditto busmechanic.
you can't go by color alone, there are several blues, several reds, several greens, etc. and there are several of each for various temperature usages. the high temp loctite I have for exhaust studs is green for example, but there is also a green that is not for high temps. the material its screwing into is also a factor - you don't want to use a strong permanent loctite on very fine threads, or aluminum threads. this is why the shop manual calls for a particualr blue loctite on the two 6mm bolts on the cam chain guide, a particular red in lots of other places, and a particular green on the cam sprockets.
the best thing to do is go by the recomendation in the shop manual - it tells you exactly what loctite # to use where. this way you know it can handle the temp and is the right choice for the application. there is serious science behind loctite, but its often overlooked. be certain you clean the threads of the bolt and what it scews into. loctite even makes a primer, and this primer is needed for the ultimate strength they claim, without the primer the strength is not quite what its supposed to be. but I use elctrical contact cleaner because the primer is hard to find since the stores don't know jack.
