Review: Great Coolant Additive - 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 desertcart'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 desertcart 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 desertcart 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.

## Questions & Answers

**Q: Compatible with hoat (orange) coolant?**
A: Yes. With all coolents actually.

**Q: How much will a 12 once bottle treat? I have a 5 gallon system and will be adding it to used coolant.**
A: First of all I would flush & refill your coolant. I recommend Prestone 50/50 Extended Life even if your vehicle calls for Dex-Cool. Go to any place that does coolant flushes. Used coolant will not get the same results. In new coolant, the results will vary. Water Wetter will be pushed to it's limits but will still work in a 5 gallon system. The temperatures might not drop enough if stretched out that far in a large system to condone the price paid. If anything does work in this category though, it is either Water Wetter or Royal Purple's Purple Ice.

**Q: Do I add this to the reservoir or the radiator?**
A: Add it to the radiator, if you can.

**Q: Can I use this with just distilled water in the winter without using antifreeze?**
A: I have tested the water wetter at a ratio of 12 oz of to 116 oz of distilled water. i buried the gallon jug halfway deep in the snow and came out and checked the next morning early and the mix was still fluid. test this for yourself.
