Didn’t lower temperature

I used this in a 2012 GMC 1500 , seemed to lower temperature, however used it my new to me 2017 Ram Cummins and didn’t see a reduction in towing temperature 🤷♂️
My Chevy 409 project was running hot. I ended up water/air pressure washing the radiator and block to get rid of all 'coolant'. I then filled the system with only distilled water and Dominator. I have seen at least a 10 degree, if not 15, cooling of my big block beast! Follow the mixture guide.
We use this in our race cars because it's cheaper than antifreeze and does a better job. I can keep a couple bottles of this in the trailer and if we damage a radiator or hose we can replace the part and grab some water to refill and we're back in business. Saves money and space.
Bottom Line
Yes, I would recommend this to a friend.

coolant boost..

great product,, did just what it boasted.. thanx..
I did not know notice a change in warm up time or anything. If there was a change it was very minimal and not noticeable. My car never overheated before so there was no change at full temperature.
Putting in my race car in the spring also so we will see. But as of now. Skip this one.
Now that it is winter I did a quick spill and fill with Amsoil car and light truck coolant with half a bottle of this. Car heats up faster and stays cooler in the summer. It works.
Bottom Line
Yes, I would recommend this to a friend.

Results are good although limited use to date

This is my first time to use Dominator Coolant Boost. In fact, the first time I have ever supplemented a coolant/water mix in over 40 years of car ownership. I recently acquired a 2016 Corvette Z06, a car known for overheating issues.
I had the coolant replaced and had the shop add Dominator at that time. The initial returns are good, but based on very little true hard driving time. My comparison is the day of the service. I drove to the shop, about 30 minutes from my home by highway. The coolant temperature fluctuated above/below 200 degrees. Later in the day, taking the same roads but with a higher ambient outside air temperature, the car ran between 185 and 190 degrees.
Definitely not a scientific testing method, but there was a difference.
