When engines are pushed to the limit—whether on the track, dyno, trail, or jobsite—heat is the enemy. Excessive engine temperatures rob power, accelerate wear, and can lead to catastrophic failure.
That’s where AMSOIL Dominator® Coolant Boost steps in.
Designed for high-performance, racing, towing, and extreme-duty applications, this advanced coolant additive helps reduce operating temperatures, improve heat transfer, and protect vital cooling system components.
What Is AMSOIL Dominator Coolant Boost?
AMSOIL Dominator Coolant Boost is a high-performance cooling system additive engineered to enhance the efficiency of your existing coolant—without altering freeze protection or boiling point ratings.
It works by reducing surface tension in the cooling system, allowing coolant to make better contact with hot metal surfaces for faster, more efficient heat dissipation.
👉 Translation: cooler temps, more consistent power, and added protection under stress.
AMSOIL Dominator Coolant Boost
- What it does: This coolant additive improves heat transfer in your engine’s cooling system so your vehicle reaches operating temperature quicker on cold days. That means faster warm-up times and quicker cabin heat, plus better overall cooling performance.

How It Works
Standard coolant can form tiny vapor bubbles on hot metal surfaces—these bubbles insulate heat instead of removing it.
AMSOIL Dominator Coolant Boost:
- Reduces surface tension
- Eliminates insulating vapor pockets
- Improves direct metal-to-coolant contact
- Moves heat out faster and more efficiently
Result: lower temps and more stable engine performance.
Easy to Use – No System Flush Required
- Add directly to your cooling system
- One bottle treats typical automotive cooling systems
- No need to drain or replace existing coolant
- Safe for street or race use
Always follow AMSOIL application guidelines for proper dosage.
