    Dominator Coolant Boost review
    By  TODD A.,  a  Verified Buyer  from  South East Texas  on  September 02, 2023
    Well we all know that it's been hotter this year than normal. Recently purchased a new truck. Right out of the gate, normal running temps were perfect middle temp indicator on the gauge. Added the Coolant Boost to it. With in 2 days of normal running noticed the general operation temps drop 1/4 of previous temp indication prior to adding it to the radiator. Impressive.
    Bottom Line
    Yes, I would recommend this to a friend.
