I still wouldn't recommend any type of lubricant. I do use silicone spray which dissipates to install hoses easier, but that's it. You gotta remember that cooling systems develop leaks over time. When you run a pressure check, you find leaks at connections. You correct the leaks by taking a couple of turns on the hose clamp that you tightened the heck out of when you installed them. The rubber has given up a little which leads me to believe that a loose hose clamp and a slick connection could mean disaster. Maybe not. I don't know. I just know that I have never seen a professional mechanic follow this procedure. I have never seen it as any kind of tip in all the professional magazines I receive.

230/8,
I use that hook for everything. I've had it for over twenty years. It is well worn and probably one of the most used tools in my box.
