Premium Radiator Additive Recommended for Racing and Automotive Applications
Superior Performance in a Wider Temperature Range
Provides Effective Heat Transfer to Increase Horsepower
AMSOIL Dominator Coolant Boost radiator additive (Product Code: RDCB) is recommended for racing applications using straight-water coolant and automotive applications using 50/50 coolant and water mixtures. AMSOIL Coolant Boost is formulated with a proprietary tiered-surfactant technology. What does that mean? Surfactants function in specific temperature ranges. The AMSOIL way is to add more and do it better – AMSOIL Dominator Coolant Boost uses multiple surfactants, allowing it to perform in a wider temperature range than competing single-surfactant radiator coolant additives. This technology provides quick and effective heat transfer inside the radiator and cylinder heads, resulting in reduced operating temperatures, more efficient operation and increased horsepower.
Racers demand lower engine operating temperatures in order to achieve maximum efficiency and horsepower on the track. However, the straight-water coolant used by many racers opens engines up to damaging radiator and water pump corrosion. AMSOIL Dominator Coolant Boost radiator additive provides racers and motorists with significantly lower engine operating temperatures, quicker engine warm-up times in cold weather and, due to its robust mixture of corrosion inhibitors, advanced corrosion protection.

AMSOIL Dominator Coolant Boost radiator additive is formulated with proprietary tiered-surfactant technology, providing quick and effective heat transfer inside the 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.
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 AMSOIL Coolant Boost, the engine was operated at 4,500 rpm until coolant temperature stabilized. Test results show water treated with AMSOIL Dominator radiator coolant additive provided a 19°F temperature reduction:
Aluminum Corrosion Test
The Aluminum Corrosion Test (ASTM D-4340) measures the corrosion protection properties of AMSOIL 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. Test results show water treated with AMSOIL Dominator radiator coolant additive easily passed the Aluminum Corrosion Test:
Metal Corrosion Test
The Metal Corrosion Test (ASTM D-2570) measures the corrosion protection properties of AMSOIL 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. Test results show water treated with AMSOIL Dominator radiator coolant additive significantly reduced weight loss due to metal corrosion:
AMSOIL Dominator Coolant Boost (RDCB) radiator additive is recommended for racing applications using straight-water coolant and automotive applications using 50/50 coolant and water mixtures.
For Straight-Water Applications:
- Add 2 fluid ounces of AMSOIL Coolant Boost per quart of tap or softened water
- Drain and refill the coolant system and add AMSOIL 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 additve/water mixture changes from pink to clear, another dosage of AMSOIL 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 AMSOIL Coolant Boost per quart of 50/50 mix
- Add AMSOIL Coolant Boost once per year or every 30,000 miles, whichever comes first. Follow coolant manufacturer recommendations for coolant change intervals.
How to Use
With engine off and cool, make sure cooling system is filled with selected coolant. Shake bottle and pour calculated amount of AMSOIL Dominator Coolant Boost additive into the radiator. Start engine, turn heat on high and run for 15 minutes. Do NOT use distilled water unless mixed with 50% antifreeze.
