80204 WaterWetter Super Coolant - 12 Ounce

My wife has a 99 C280 so I have to take extra care when buying fluids and parts etc since its a German performance automobile (that's sarcasm). All sarcasm aside its a great car and runs very well (no thanks to my tinkering or mechanical abilities). This stuff is highly reccomended in several benz forums from the late 80's models to the fresh of the lot models. I was skeptical at first thinking it was just fancy water and really didn't do anything performancewise. A few summers ago I changed the coolant in the car and noticed that the car would heat up 10-20% more than usual. Nothing to the point of damaging the engine (thankfully I replaced the thermostat to be thorough on this change) but still higher than I was used to. I grabbed a bottle of this at my local Autozone and put it in the car. After a few days of driving the stuff must of mixed fully with the rest of the coolant water mix and the car was nearly back to its old self. The new thermostat had a higher temp trigger so the engine does get a little warmer than before but not anywhere near the levels it was getting before I put the Water Wetter into the coolant tank. I recently changed the coolant again (DC summers are not friendly to engine staying cool)and this time premixed the water coolant and water wetter all at once and noticed an immediate improvement in temperature. With the AC blasting and going at 50mph we used the get the car nearly to 3/4 temp setting (when the thermostat would open and let coolant run from the radiator to the engine block) but now under the same cricumstances the car stays one tick above 1/2 which is 80 C on the car. This stuff makes some kind of chemical or physical change (never figured out the exact difference between those two in high school) to the coolant water mix. Something about making it so that water or coolant is more efficient at disapating. Don't quote me on this but I think that is the correct explanation. Now for a review on Amazon's shipping. I ordered this and the fancy coolant on the Sunday before Memorial Day. I figured well they will process the stuff Tuesday and maybe send me a shipping notice Tuesday night or Wednesday morning. I saved over 200 bucks by doing this easy repair myself so I didn't mind the wait. However, leave it to Amazon to prove me wrong. Not only did I get the shipping notification Monday (memorial day!) I received the coolant and water wetter on Tuesday before 12pm while I was at work! Go figure I paid for the free super saver shipping or whatever it is called and they shipped it with Fedex next day early delivery speed. Now I would not count on this everytime from Amazon but it is nice to see that if an item is nearby and available for shipping they process it quickly and have it out on the truck before you know it.

Water wetter worked for me, I saw a 10 degree drop in my cooling system. Big block Oldsmobile, aluminum radiator with duel electric fans.

Idk if it works or not. But...i do notice is helping my car keep it cool so to me...it does work. Depending of the size of the radiator or the coolant tank. You might need to add 2.

Added the additive a few days ago. Red Line has quality in their name and I'm sure this will work as intended.

I gotta personally look this stuff up on YouTube and see how to properly use it! But I believe it just pour the entire bottle into your coolant for added and better protection , it’s supposed to keep your car running cooler!!

Been using water wetter for years. One of the best products, used it in my tractors and 4 Wheel Dr. trucks. It works as it states.

It's a good product for profitmance vehicles , helps the cooling system be more efficient .I'm using it in an air to water supercharging system ,seems to lower operating yemps

Added to KTM Duke 690 and instead of 11 bars on the guage, I'm down to 9 bars in the heat of Shreveport. Good stuff!
