About DOMINATOR Coolant Boost
A cooling-system additive to consider for compatible applications alongside the required coolant or water mixture. A cooling-system service should account for the existing coolant chemistry, system capacity, and the vehicle’s required mixture. Select coolant and additives as separate parts of that plan.
Before you choose
Check chemistry compatibility, dilution requirements, and whether the product is a coolant or an additive. Follow the current label rather than mixing by color.
Can I select coolant by its color?
Color alone does not establish compatibility. Match the manufacturer specification and product chemistry, and follow the required dilution and system-preparation instructions.
