Yes I have used this in the past when I first bought my 78, but my vette guru here in Dover has since added a product from BG which he says is better than most of the off the shelf stuff....Honestly, I never did notice any difference in operating temps...And I do check it regular with a temp gun..
cotteneg,
10 years ago when I had my BMW M3, there was a popular mod where you would remove the engine driven fan and replaced the temp sensor with the E30 sensor to trigger the auxiliary fan to come on early. The auxiliary fan therefore became responsible for cooling the engine. The mod was incredibly popular and many aftermarket folks offered a "kit" that included WaterWetter. When I did the mod, I left the WaterWetter out to see what would happen. I didn't over heat, but the temps were a little too high. I added the WaterWetter and temps dropped 10 degrees. Pretty cool stuff. It's not a band aid for a failing cooling system though.
Thanks
I put them in balance with the 99% of people who have tried it and said it made no difference.
There's a fascination with these cars that cause people to constantly stare at the engine temps gauges instead of watching the road. This, combined with an irrational expectation of having the engine run cooler than it was designed to (or capable of doing) when new. Some owners inexplicably run straight water in their cars, all part of an effort to out-engineer GM.

Some have noticed marginally cooler temps when used only with straight water and no anti freeze. Obviously you want the protection that anti freeze provides so it's not practical in street driven cars.

The fascination of C3 owners being obsessed with their temp gauge comes from dealer acknowledged issues with the factory cooling system. Our cooling problems are infamous. I also understand that WaterWetter has mixed results. I can definitely tell you that it worked in my BMW. In a Corvette? I don't know. I've never tried it. C3 cooling systems require a larger volume of coolant than my little E36 M3 required. If I were to run WaterWetter in my 70, I would use 2 bottles. But in my experience, most people that inquire about WaterWetter are reacting to a cooling system problem where an application of WaterWetter, be it 1, 2, or more bottles won't overcome what is really wrong with the cooling system to begin with. In my case, I wouldn't dream of using WaterWetter in my system because I've recognized that our C3's have cooling issues, especially with modified power plants, so I improved the cooling infrastructure with a Dewitt's radiator and twin fans.
No results here from Water wetter, high flow pumps, and lower temp thermostats, you name it I tried it through the years. Wasted time and $$$...for me at least.
With a properly tuned engine and the rest of the cooling system ALL there and in working order, the stock system should do the trick. If it dont, its time for a Dewitts aluminum radiator.
I used to have cooling issue on the track. A guy running BP told me the shroud corked off air that would otherwise be rammed through the radiator. He also recommended a flex fan. I tried it (retaining the stock parts) and the issue went away. The only time the temp gauge creeps up is stuck in traffic on hot days. If I can get moving, the temp will drop. I figured I might try Water wetter as a possible help with the rare time I get stuck in traffic. But figured I ask here to see what people thought.
In the early years of owning my '68 BB I had overheating issues - flushing system gave me a couple of degrees, as did a new aftermarket water pump and moving the front license plate, the Water Wetter also gave me about three degrees. The biggest reduction was a DeWitt ally rad and sealing off thoroughly the radiator/shroud/front bulkhead mounting.
How accurate is a gauge? I put in Autometer gauges and senders in last year. comparing the water temp gauge to two thermal IR guns which read the exact same. the gauge is 15 degrees high.
The stock fan shroud makes the fan blades move the most air because the blades need radial surrounding to work the most efficiently in pulling air through the radiator core.
The stock fan blades are poorly designed and have rpm limitations. That is why I went to the stainless steel 18 inch 10,000 rpm brand flex fan.
My 79 L-82 7 blade thermal clutch fan would go into free wheel as rpm climbed and the thermal spring never seemed to work as advertised. As my motor rpms increased to 7000 rpm I believed that I had exceeded the safe over driven speed of stock setups.
In the end the real fix is aluminum big thick radiator,aluminum pump and twin spall electric fans. Oh and intake manifolds plumbed to cool the rear cylinders
Gkull you ever tried these? http://www.summitracing.com/search/p...echanical-fans
Far as mechanical fans go Im sold on them.
Wont break move lots of air and weigh a few ozs
Used and abused these for yrs loved it.
If this round of rad/fan etc upgrades doesnt cut it my old nylon fans going back on.

No those little blades don't move enough air. I had something like this. I might even still have it on a shelf. It was blue and the edges were so sharp that after getting cut I sanded the edges round.
From: Who says "Nothing is impossible" ? I've been doing nothing for years.
I have tried it in various engines and it works to some degree, get it ho ho. My warmed over 355ci seemed to have a temp drop with 2 bottles of the stuff, and my previous 406ci but for some reason it doesn't really do any thing with 427ci I have in there now.
I would like to ask a question, since my car is only driven in the summer and have a heated garage what is the best combination for cooler running engine.
Would straight or distilled water combined with a little antifreeze or two bottles of water wetter cool it down a bit. I have stainless headers and I like the look therefore I don't want to coat them, but I am sure they contribute to the overall underhood temps. I have two 13 inch Spal fans but on hot days seems the one fan is working all the time in stop and go traffic
