Cool Radiator Water
I have a question regarding a product called Water Wetter. It seems that my '98 tends to get a little hot when idling in traffic. I have the correct mix of antifreeze and water. My question is can I safely add the product Water Wetter to my mix and not cause any engine performace problems? They claim it can lower the temp by 20 degrees or so. With that much temp difference, I just want to make sure that it won't affect how the engine runs and also that it won't affect the antifreeze mix. My engine has not gotten so hot that the electric fans have had to come on (which is a good thing). So, is this product safe to use. Any adverse problems for anyone out there? P.S. in normal driving the temperature stays right on the money as long as I am moving. Thoughts anyone?

Hi, i´m a new here on this forum. Hi Hi :-) I´ve had in a 1.65bar cosworth and yes it made a difference in real world then, also worked in a Rover V8 but when i spilled a bottle in my C5-2K i could not register a singe degree on the temp meter in "normal use". Serious stuff - in the right engine/situation? Maybee a track day would show more result? Still quality stuff and if you use only water + water vetter there should be some difference but the water system in a LS-1 is working normally in high(relatively) temp areas where the antifreeze is needed to keep up the boiling point so antifreeze+water+vetter migh be the safest route ? Just try it.

Most that want to run cooler put in anywhere from a 160 to 180 thermostat and then get the fans reset where they come on sooner. I put a bottle of water wetter in my 01 coupe and couldn't tell any difference. I recently changed to a 180 stat and will have my fans reprogramed when I get a dyno tune.

Only true in certain cases. If you are driving at speeds higher than 45 to 50, with a 195 stat, you will run hotter than if you are running a 160. Also, if you reset your fans to come on at lower temps the 160 will keep your temp lower than if you are running a 195.
As for the water wetter, it does work, but not very well in 50/50 coolant to water. It's effect is only on water, so the higher percentage of water in the system, the better it will work. For a race only vehicle, run distilled water and water wetter, it'll run cooler than with coolant.

On my V6 Camaro ,with no hi-lo fan switch controller, (which I plan to do)a 180* thermo made it run cooler as long as the car is moving. Even an halacious traffic jam the car runs cooler with the air on than before,'cause the fans are on.Takes less time to cool back down too.

You said the same thing in a previous thread. If it's so bad what do you recommend in it's place? Sounds like a lot of Doom saying to me.
I wonder how many C5's are out there with a ton of miles and clean cooling systems.

I have a Dexcool-equipped Toyota with 123k miles. I recently opened it up to change the t-stat. Clean as a proverbial whistle inside!!
The problem with Dexcool is when you mix it with conventional green antifreeze. If you don't get every last ounce of the green stuff out before you go with the orange dexcool, you will have increased corrosion problems. The two types don't like each other.
To say that Dexcool by itself causes problems is just plain wrong....

I had a 97 Z-28 with 87K and sold it to get my 03 Vette. The water pump went on the LT-1 so on went a new one. I'd say that things were much cleaner with the Dex, and with the green stuff. My .02

water wetter
I really couldn't tell a difference when I added water wetter to my C5. I live in Atlanta and my car runs warm during the summer in traffic regardless to what I use. Sometimes the coolant temp goes up to 220 and then slowly comes back down. I don't believe water wetter will help much in stop and go traffic. Perhaps it will make a difference when the care is moving but I don't have a problem as long as the care is moving.

A colleage of mine use Water Watter and Distilled Water in his 2002 ZO6 and had ran numerous sanctioned road courses: Gamblers, Silverstate Classic, etc.
I run mine 25% Dextron, 1 bottle Redline and distilled water. Im In Cali so I have no concerns about freezing water in my radiator.
