I have an older Bounder with a 460 engine I just had to have a water pump replaced and all new coolant put in is it worth putting in the waterless coolant ? I've heard about it but don't know if i...

My Bounder is a 92 so I think it has a copper brass radiator, how often do you change the coolant if you go with regular coolant I waited four years and it screwed everything up from what I was told I was also told I should change it every two years...
From what I understand the waterless coolant creates no mineral buildup or reaction with the metals
Runs cooler,( I'm in AZ a lot) and it lasts 4 times as long
No mineral buildup: true, but also true of conventional coolant made up with distilled water.
No galvanic reaction with dissimilar metals: true.
Lasts longer: true. (Two years seems rather short for good quality conventional coolant to me, but I also don't live anywhere near Arizona.)
Runs cooler: definitely not true in general, as the specific heat of water is much greater (like almost twice as good) as that of waterless coolant. It will continue work at higher temperatures where water would boil into steam, so there's not a danger of "boiling over," but the engine will run hotter overall. (Whether or not the engine running hotter is any cause for concern is another matter entirely, and one that's not quite so easy to answer.)
IMHO it's not worth the extra money in general, though perhaps in some special situations it would make a lot of sense.
