I came across an add for hyper lube super coolant. it purports to lower engine temps by up to 20 degrees and has a special "wetting agent" to help coolant better penetrate heat transfer areas. Anyone try it in a fiero with a conversion, i dont have a cooling problem but what the heck. I am very reluctant however to putting additives in my radiator. Any thoughts?
If you have a stock 2.8 or 2.5 in the Fiero, you're probably better off just putting in a 180 degree stat, and a 195 degree fan switch, if you want to lower the temperatures 20 degrees.
I wouldn't bother with it. It's not going to save you any money, and additives may make the coolant more corrosive, depending on what's in them. Even Dexcool is pretty corrosive if not properly maintained, and it's used in all new GM vehicles, and has been for some time now.

I will disagree with the first two respondants to your original posting.
This technology has been used for years, it's nothing new and it works by preventing the coolant from boiling on the hot surface.
Think of it this way, even though your coolant temp is 195, and the pressure in the system raises the boiling point to 250, the hot surface that is being cooled reaches well over the boiling point of the coolant. Just like in a pan of water on the stove, little bubbles form on the heated surface, and thouse bubbles reuce the transfer efficiency of the coolant.
This type of additive prevents the formation of the little bubbles, increasess the transfer efficiency of the coolant, and the heated surface cools faster.
For more info, and to talk to someone who uses it, PM steve25 here on the forum.

I used a product in a different vehicle (truck) that had always run a bit on the hot side even with a perfectly functioning cooling system and the proper blend of anti freeze -- (water wetter was the name of the product) - It did improve the cooling of the vehicle - guage posted lower and more acceptable temps and the vehicle just seemed to preform better -- it was also easier to drive with the calmed down temp guage giving added peace of mind.

i have used red-line water wetter. it works by breaking the surface tension of the water a similar additive is used in hi end computer cooling systems. This breaking of the tension is what allows the water to flow better and not bubble or boil as previously stated by making the water slicker and able to pull more heat from the surface decreasing its tendency to boil the coolant.

I love Water Wetter, I use to have my nitrous 2.9 V6 and used the nitrous a lot more than I should have, "Hey it made trips to the grocery store much more fun" I would notice that after using it in city streets the engine temp would spike rather quickly, on the suggestion of the place that filled my nitrous bottles, I added the water wetter to a 75% water 20% antifreeze and one bottle water wetter mix. The temps were much more stable, car ran cooler and overall just performed better.
Now its part of my normal spring routine, every spring I drain out the cooling system, flush it and put in fresh distilled water 1 gallon of antifreeze and 1/2 liter of water wetter. I have not had a Fiero overheat in years.
