Radiator fluid additives to reduce temperature
Since I live in the desert and I'm a daily driver, I'm tempted to add one of the locally available additives to reduce the running temperature. I run about 200 to 210. What is your feedback. Do these additives really work or do they cause more problems than the solve?
Thanks,

I would like to hear if the fluids do make a real world difference or not. (Meaning I don't buy the

Water Wetter Super coolant is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30°F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass, and bronze systems.

Another thing you can do too is change your mix to 65/35 or 70/30 water to coolant ratio and add a bottle of Water Wetter. The products like Water Wetter perform their best with water, so the higher the water concentration, the better it performs.
Look at the applicable information and do your calculations as to the mix that gives you a higher water concentration but yet still has enough coolant concentration to cover you in the winter where you live. Use distilled water too. It's cheap too.
With an 18 lb cap, I run a 65/35 concentration and a bottle of Water Wetter here in the "Land of the Parched Earth", otherwise known as the Texas Gulf Coast region. Of course I now have a DeWitts 2 row radiator too, but I was doing this long before I added the better radiator.

If you're running 200-210 in traffic, yep, that's common, I have a 160* t-stat (and tune), and here, where we see 96-104 temps, I run 197-207 in traffic, but 183-187 on the highway cruising at 80mph.

Turn on the air conditioner. The second fan comes on and the temps go below 200. At least that's they way it works with my Z. If your temps are that high with both fans running, I'd use the above advice and get a tune and lower temp T stat.

I have used the Red Line Water Wetter in a small block Chevy I used to drag race and in an old 88 BMW I own as I live in Florida and have had good results.
On some of my other cars I have run a switch to manually control the electric fans so I can run them earlier than the thermo switch kicks them on. Haven't done anything with my C5 as it seems to be OK in the heat so far.

I've run water wetter in other cars and it has helped. I had a tune done to change the low fan to come on at 190 and the second to come on at 195. The car has not hit 200 since. Last year in traffic the car would hit 230
so any time it came near this, I would turn on the a/c to cool it down. This year, no problems yet.
