AMSOIL Dominator Coolant Boost
Radiator Coolant Additive

Superior Performance in a Wider Temperature Range

AMSOIL Dominator Coolant Boost is formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiator and cylinder heads. Surfactants function in specific temperature ranges. AMSOIL Dominator Coolant Boost contains multiple surfactants, which allows it to perform in a wider temperature range than single-surfactant coolant additives. This results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather.

Corrosion Inhibitors

AMSOIL Dominator Coolant Boost contains a robust mixture of corrosion inhibitors that protect the radiator, heater core, water pump, cylinder heads, engine block and intake manifold from the damaging effects of corrosion.

Temperature Reduction Dynamometer Test

To test the temperature reduction capabilities of AMSOIL Dominator Coolant Boost, dyno tests were performed on a Chevy 350 cubic inch engine with an aluminum block and cylinder heads. Running the test with both straight water and water treated with Coolant Boost, the engine was operated at 4,500 rpm until coolant temperature stabilized.

Aluminum Corrosion Test

The Aluminum Corrosion Test (ASTM D-4340) measures the corrosion protection properties of AMSOIL Dominator Coolant Boost in modern automobile and high-performance race engines with aluminum cylinder heads. A cast aluminum puck was heated to 275°F at 28 PSI and exposed to the test coolant mixture for one week. Weight loss of less than 1.0 mg is required to pass the test.

Metal Corrosion Test

The Metal Corrosion Test (ASTM D-2570) measures the corrosion protection properties of AMSOIL Dominator Coolant Boost in automotive cooling systems. Using ASTM corrosive water designed to simulate hard and corrosive water in degraded coolant, six metal coupons constructed of the most common metals in automotive cooling systems were exposed to the test coolant mixture at 190°F. The coolant was maintained at a temperature and flow rate equivalent to the operating conditions seen in most passenger vehicles. Corrosive weight loss suffered during the test determines the additive's corrosion protection properties.

Recommendations

AMSOIL Dominator Coolant Boost is recommended for racing applications using straight water coolant and automotive applications using 50/50 coolant and water mixtures.

How to Use

With engine off and cool, make sure cooling system is filled with selected coolant. Shake bottle and pour calculated amount of Coolant Boost into radiator. Start engine, turn heat on high and run for 15 minutes. Do NOT use distilled water unless mixed with 50% antifreeze.

Dosage

For Straight Water Applications:

• Add 2 fluid ounces of Coolant Boost per quart of tap or softened water
• Drain and re-fill the coolant system and add Coolant Boost once per year or when indicated by color change. A distinctive pH color change indicates when the pH has fallen to a point where corrosion can set in. When the Coolant Boost/water mixture changes from pink to clear, another dosage of Coolant Boost should be added. Monitoring the pH level will ensure all vital areas of the cooling system are protected against corrosion.

For 50/50 Coolant/Water Applications:

• Add 1 fluid ounce of Coolant Boost per quart of 50/50 mix
• Add Coolant Boost once per year or every 30,000 miles, whichever comes first. Follow coolant manufacturer recommendations for coolant change intervals.
