Winter cold starts are not only hard on your engine, they can feel brutal for shivering passengers. Some days, the heater can’t start blowing warm air soon enough. AMSOIL DOMINATOR Coolant Boost offers a solution that helps warm your vehicle faster on cold days – while also lowering engine operating temperatures and improving overall engine performance.

How It Works

DOMINATOR Coolant Boost is formulated with three surfactants to provide consistent performance from cold to hot temperature extremes. Our proprietary tiered-surfactant technology reduces the surface tension of water and antifreeze throughout a wide temperature range to allow better contact with metal surfaces. That contact improves heat transfer, which in turn helps transfer heat away from hot engine parts. The result? Your vehicle warms up an average of 54% faster, ensuring a more comfortable cabin and faster defrost on frosty mornings.

Key Benefits

1. Faster warm-ups: By reducing the time it takes for your engine to reach operating temperature, DOMINATOR Coolant Boost helps you get on the road quicker and more comfortably.
2. Enhanced heat transfer: The product reduces engine operating temperatures by up to 25°F (13.8°C), improving efficiency and preventing overheating.
3. Corrosion protection: It safeguards your cooling system against corrosion, extending the life of critical components like radiators and water pumps.
4. Versatility: Compatible with all water sources including distilled, bottled or tap, and is safe for use with antifreeze mixes. It’s a flexible solution for various vehicles and conditions.
