Works great
This product worked great for me. My car wasn't quite overheating but the temp was going up and down. I also had no heat unless the rpms were higher than running speed. I put this stuff in just to see if it would help and wow. The heat came on almost immediately and the temp gauge went back to normal with no fluctuations. If you are having a temp issue I highly recommend this product. Worked great and I didn't have to go to a mechanic who would probably tell me I needed an expensive repair to get my car working properly again.

    Great for intercooler systems
    I use this on my 01 Ford lightnings intercooler system. I like the yellow color, it matches my prestone coolant, plus it helps lower my iat2 temps. Ive used other water wetters

    Worked 4 me.
    I used this in my Can-Am SxS as it was running a little warm playing in the sand and off road, and it is now running in the normal range. Very inexpensive fix for me. Great product.

    i use it in my water cooled computer?
    most cooling fluids in a computer are the same as what is in your car but much diluted, with this i used 1oz with water i have a 8 core processor and 2 radiators, computer cooling is quit the same but in a computer the pressure in the cooling loop is only 1 or 2 psi, so i have noticed no change in temps but i do like the properties it has i have been running it for 3+ weeks, the green is uv sensitive a black lite makes it easy to check for leaks the other qualities of this fluid is nice also i so far have no dulling of the plastics it appears to be very safe and is very stable and for what i have tested it works as good as costume cooling fluids sold for 20 x the price of hyper l&*e i'll try anything at least once this i will keep on using i recommend it highly i wish it came in other colors with the uv properties

    Great additive to your coolant
    I have added this in two vehicles and in both cases have seen the difference it has made. Not only has it lowered temperatures, but I have noticed that in cooler weather vehicles warm up quicker. Recommend you add this, my vehicles has 50/50 anti-freeze water mix.

    Excellent Product
    I have used Water Wetter in the past but did see ay difference in my cooling temperature, so I decided to give Hyperlube Super Coolant a try and it did make a significant drop in my cooling temperature.

    Works much better than I expected
    I tried this in my car first and could not believe the difference it made. My car would over heat on hot 100 degree days with the air on. I put in 1/4 of a bottle as that all I could put in without draining the radiator. Big difference right away. In the morning with the heater on heater puts out more hot air right away. In the hot 100 degree days the guage showed the same but the radiator fan came on eariler and staied on longer. Before I put it in when I shut my car off the radiator would sound like it was boiling and fluid would go into the overflow tank. After putting it in no more boiling sound. They call it a wetting angent to allow the engine heat to transfer to the water. You will know it works just by turning on your heater in the morning and see how long before it puts out heat. Then do the same after putting it in and you will be shocked how fast the heater works. It works the same way in the radiator to cool the engine. I thought the temp gauge would show lower but it does not. I think this is because the heat also tranfers to the heat guage pick up. I am going to put this in all my cars now. My wife car never over heats but on her two mile trip to work the heater puts out no heat. My car was also like that but now put out good heat before the first mile. It also says it has corrosoin protection and prevent rust in the engine.
