I've read almost every WW thread out there and they all end up the same. People say its not needed, creates gunk etc. However What about the water pump? I've never had a water pump fail until I've put WW into my 240sx. Maybe some WW seeped past the WP seal and dissolved the grease from the bearing?
Years later I put amsoil coolant boost in my 240sx, and in the winter it took about 25 minutes for the car to reach 180*f. It still takes a while in the summer, and this is with a new OE t-stat. 50/50 ratio. But now on my track car I definitely need some assistance cooling down two turbos. I'm hoping to run 25% coolant and maybe some coolant boost. I'm just concerned for the seals, and any other type of acidic properties these products may have.
Coolant boost seems better than WW on the corrosion, so I do not think that the things will become worst if you add it.
I used to use WW, it was more oily than Coolant Boost which ha no viscosity, so I do not think that it will lubricate the water pump.
So far the car goes better since I put it, I'm sure because a more uniform temperature of the engine,it has lowered the hot spots that are present in every engine especially on the engines prone to sludge.
