    Dropped the temp by 10 degrees. Literally.
    By  EARL,  a  Verified Buyer  from  hampstead,NC  on  July 23, 2021
    Temp was running at 210 degrees continuously. After adding Dominator Coolant Boost the temp dropped to 180 degrees across the rpm range. I have never found another coolant additive that was able to drop the temp by even 10 degrees. Dominator works great
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent product
    By  JR,  a  Verified Buyer  from  New Jersey   on  July 03, 2021
    Coolant Boost is a must add in all your vehicles. I’ve noticed instant results. I like the piece of mind even in newer vehicles as everyone knows heat is a killer to any engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Cool collant
    By  SIR JIMMY,  a  Verified Buyer  from  Orrville  on  July 02, 2021
    I did a total flush and I added this product. To be honest, I did not see, hear or feel a difference. I will know more by winter season.
    Bottom Line
    Yes, I would recommend this to a friend.

    It Works!
    By  MICHAEL,  a  Verified Buyer  from  Western Wisconsin   on  June 12, 2021
    Every vehicle I used Coolant Boost in showed a noticeable difference in warm up time in cold weather. It gives me confidence that my engine is protected in hot weather.
    Bottom Line
    Yes, I would recommend this to a friend.
