You have been told correctly. The liquid should be blue. It acts like a holding agent whereas the red liquid acts like a superglue. A lot of people say to use it on the engine block mounting screws but personally I have never done so. If you are using philips head screws to mount the engine the proper sized driver should provide ample torque to be sure the screws are tight enough not to come loose. Its inevtiable that you will strip the head out of a philips style screw. I have recently wrung one out without using any loctite. If you can find them I would personally recommend using a hex head bolt to mount the engine to the chassis. The hex socket is far more robust and will not strip.
Heres a picture of the type I mean
(NOTE- This is not the correct size. It was just the first picture I found of the correct type)
