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.

Well, I used it. The temperature was good on the car. Has an overheated, but I also have a new radiator in there too. A little extra help never hurt hurts

This product works.

Quality product

Makes a significant difference in reducing coolant temperatures. Been using this product for many years in various vehicles, and noticed that the coolant temperature is lower, may be a significant factor in motor life due to oil thinning that is temperature dependent.

Goes on every coolant flush I do. Really helps keep coolant temps consistent on a turbo LS

Works as described. I have used Redline water wetter for many years.

This took a couple of extra days to receive beyond the expected date.. not sure if this was the seller's issue or a shipping issue. I did receive the correct product at a decent price.

Great product

ok

Redline say this is supposed to decrease the chance of corrosion and improve the thermal conductivity of your engine coolant, thereby transferring heat away from your engine block more effectively. You'd probably not notice a decrease in your engine temperature unless you were already suffering from overheating problems, as most vehicles have a thermostat in the block that gradually opens as the engine reaches its designed operating temperature, directing all the water around the radiator instead of keeping it looping round the block. Thus, any improvement seen by this product would be invisible, as you'd just find the thermostat not needing to open as fully. The benefit would be in protecting your engine, added piece of mind, and elimination of any hot-spots that might encourage knocking and pinking. I went on holiday last summer, which would have involved a 500-mile round-trip even if I didn't do any driving at all when we got down to our destination. Seeing as my car had just turned 35, I figured it wouldn't hurt to try this stuff - especially as she's been knocking and pinking over the past year whenever fed standard unleaded, even though I've always used the same ignition timing, and the temperature gauge had been a little high in heavy traffic occasionally too. So when I did my service right before setting off, I added this stuff to my usual 50/50 blue coolant mix. Well, the temperature gauge definitely stayed in the area I like it to be in, so I guess it does what it's supposed to. Additionally, I'd say the pinking issue was slightly better although not cured. (I suspect that's more down to the ethanol content of 95 octane leaning the mixture out too much, rather than hot-spots in the block, though. I don't want to retard the timing any further as it used to be fine on 95-octane and too little ignition advance will reduce power and efficiency, and increase temperatures). All in all, I'd say this stuff does what it says on the tin. Hopefully its anti-corrosion properties also work too.

Ero scettico ma funziona veramente, complimenti ho abbassato di 4/5gradi la temperatura media in marcia 👍🏽
