AMSOIL Dominator® Coolant Boost

Formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside the radiator and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower, and significantly reduced engine warm-up times in cold weather.

Racers demand lower engine operating temperatures in order to achieve maximum efficiency and horsepower on the track. Many racers use straight water as a coolant, which invites damaging radiator and water-pump corrosion. AMSOIL DOMINATOR® Coolant Boost (RDCB) provides racers and motorists with significantly lower engine operating temperatures, quicker warm-up times, and advanced corrosion protection.

DOMINATOR Coolant Boost is formulated with proprietary tiered-surfactant technology, providing quick and effective heat transfer inside radiators and cylinder heads and resulting in reduced operating temperatures, more efficient operation, increased horsepower, and significantly reduced engine warm-up times in cold weather and before a race. Coolant Boost also 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.

Engine Warm-up Reduction Test
To test DOMINATOR Coolant Boost’s ability to reduce engine warm-up times, the product was added to an antifreeze/water mixture in a V-8 test engine. The engine was run at idle until it reached a prescribed temperature of either 120ºF or 180ºF. The ambient temperature was maintained at 30ºF to simulate winter conditions.

Temperature Reduction Dynamometer Test
To test temperature-reduction capabilities, controlled engine dynamometer (dyno) tests were performed on a 350 cubic inch Chevy* engine with an aluminum block and cylinder heads. In each phase of testing, the engine was operated at 4,500 rpm until the coolant temperature stabilized. As benchmarks for the test, straight water stabilized at 220˚F and a 50/50 antifreeze/water mixture stabilized at 228˚F.

Cast Aluminum Alloys Corrosion Test
The Cast Aluminum Alloys Corrosion Test (ASTM D4340) measures corrosion protection properties in modern automobiles 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.

Corrosion Test in Glassware
In the Corrosion Test in Glassware (ASTM D1384), six metal coupons constructed of the most common metals in automotive cooling systems were totally immersed in aerated coolant mixtures for 336 hours at 190˚F. Each test was performed three times to determine the average weight change for each metal. The ASTM sets the allowable weight loss maximums for each metal.

Simulated Service Corrosion Test
In the Simulated Service Corrosion Test (ASTM D2570), six metal coupons constructed of the most common metals in automotive cooling systems were exposed to ASTM corrosive water designed to simulate hard and corrosive water in degraded coolant for 1,064 hours at 190°F. 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. The ASTM sets the allowable weight loss maximums for each metal.

Recommendations
Use DOMINATOR® Coolant Boost with racing applications using straight water as coolant and automotive applications using antifreeze mixtures.

Directions: With the engine off and cool, make sure the cooling system is filled with selected coolant. Shake the bottle and pour the calculated amount of Coolant Boost into the radiator. Start the engine, turn the heat on high, and run for 15 minutes.

Dosage: For straight water applications, add 2 fl. oz. of Coolant Boost per quart of water. In antifreeze mixtures, add 1 fl. oz. of Coolant Boost per quart of antifreeze.

Frequency: In applications using Coolant Boost with straight water, drain and re-fill the coolant system and add Coolant Boost once per year.

In applications using Coolant Boost with antifreeze/water mixtures, add Coolant Boost once per year or every 30,000 miles, whichever comes first. Follow coolant manufacturer recommendations for coolant change intervals.
