??? Is this safe to use on automotive water pump bolts ??? Will I be able to remove the bolt later down the road ???

No, you shouldn't use the red variety on a water pump, and no, you won't be able to remove it unless you apply 450F heat and remove the bolt with 250ft lbs of torque, assuming the bolt can even take anywhere near that without shearing off. (highly unlikely, so then you'd really be in for some fun).

I need something strong to mount support brackets for a heavy clothing rod in a closet where I cannot drill holes. Will this one work?

Heady duty threadlocker might be the wrong strength. The blue color threadlocker Loctite ought to be strong enough for a hanger rod.

I am looking for a “ Torque Line” product, that puts a bead on a bolt and securing mechanism, and will break indicating something moved loose?

Like this? https://www.amazon.com/TSI-Supercool-12848-Yellow-Warranty/dp/B01JBXHLI0/ref=sr_1_5?keywords=drain%2Bplug%2Btamper&qid=1572673001&sr=8-5&th=1

Will this work for holding a stud bolt head onto a door handle of a pickup?

Thank you for the question. Loctite Threadlocker Red 271 works on close fitting, threaded metal fasteners up to 1”.
