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. 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 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 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.

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 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.

Dominator Coolant Boost Reviews

Greatly Accelerates Warm up

Questions Answered on Amsoil’s Coolant Boost

1.
Question:
What is the most common cause of overheating?
Answer:
Over time, silicates in antifreeze and minerals in water contribute to the formation of scale inside radiators. This process is accelerated as antifreeze becomes degraded or through the use of high mineral content water. As these materials circulate in the cooling system, they reduce flow through radiator tubes which reduces heat transfer, increases operating temperatures and ultimately leads to overheating.

2.
Question:
When is straight water used as a coolant?
Answer:
Straight water coolant is commonly used in hot-weather climates where freezing is not a concern. Also, most race tracks do not allow the use of antifreeze as a means to avoid clean up issues associated with spills.

3.
Question:
What are the main benefits of using Dominator® Coolant Boost (RDCB)?
Answer:
Dominator® Coolant Boost lowers engine operating temperatures to reduce the potential for boil-over and overheating associated with engines worked beyond normal operating conditions. It also contains a specially designed technology that does an excellent job fighting corrosion in straight water systems and enhances the corrosion protection provided by antifreeze packages.

4.

Without oxygen, rust and oxidation cannot occur.

9
Question:
How does Dominator® Coolant Boost prevent electrolysis and galvanic corrosion?
Answer:
Galvanic corrosion occurs when antifreeze acts as an electrolyte between dissimilar metals in cooling systems. Dominator® Coolant Boost contains a premium ingredient called molybdate, which forms a film on the surface of aluminum, controlling the transfer of electrons. This film helps minimize the tendency for electrolysis and galvanic corrosion.

10.
Question:
How is Dominator® Coolant Boost added to a vehicle?
Answer:
With the ignition off and the vehicle’s engine cool, open the radiator cap and pour in the proper dosage of Dominator® Coolant Boost. Then start the engine, turn the heat on high and allow the car to run for at least 15 minutes or until the thermostat has opened. This will circulate Dominator® Coolant Boost through the entire system, providing full protection to the radiator, heater core, water pump, cylinder heads, engine block and intake manifold.

11.
Question:
What if the vehicle’s cooling system is already full?
Answer:
Open the petcock on the bottom of the radiator and drain approximately one pint of coolant in order to create sufficient additional capacity for the addition of Dominator® Coolant Boost. If a petcock is not available, siphon the coolant from the top of the radiator. Dominator® Coolant Boost may also be added to the coolant expansion tank or reservoir, as long as the vehicle is driven regularly. It takes approximately 4 to 5 complete heat-up cycles for Dominator® Coolant Boost to make its way into the cooling system via the coolant reservoir.

12.
Question:
What is the dosage required for maximum protection from corrosion, electrolysis and scale build-up?
Answer:
When mixing with 50/50 antifreeze and water, add 1 fluid ounce of Dominator® Coolant Boost for every quart of 50/50 mix. With straight water coolant, add 2 fluid ounces of Dominator® Coolant Boost for every quart of straight water coolant.

13.
Question:
How often should coolant be replenished with Dominator® Coolant Boost in order to maintain full protection?
Answer:
With straight water systems, drain and re-fill the coolant system and add Dominator® Coolant Boost per dosage instructions when indicated by color change or once per year, whichever comes first. When using a 50/50 antifreeze & water solution, add Dominator® Coolant Boost once per year or 30,000 miles, whichever comes first. Follow the antifreeze manufacturer recommendations for coolant change intervals.

14.
Question:
Is Dominator® Coolant Boost compatible with all types of antifreeze?
Answer:
Dominator® Coolant Boost is compatible with all types of antifreeze, including ethylene glycol and propylene glycol. When using a 50/50 antifreeze water solution, AMSOIL Antifreeze & Coolant (ANT) is recommended.

15.
Question:
If more than the recommended dosage of Dominator® Coolant Boost is added, will performance increase?
Answer:
Exceeding the recommended dosage will not yield any additional temperature reduction performance, nor will it yield any additional corrosion protection.

16.
Question:
What are the AMSOIL recommendations when using straight water coolant?
Answer:
When using straight water as a coolant, the most robust form is softened water because the softening process removes impurities and minerals from the water by exchanging them for more beneficial minerals. Unlike distilled water, softened water will not act as an electrolyte, thereby minimizing damage from electrolysis. Although softened water is preferred, Dominator® Coolant Boost contains an advanced formula that allows use of low quality water (i.e. well water in cooling
systems without concern of damage or scale/deposit buildup.) Distilled water is not recommended in straight water systems.

17.
Question:
What if no temperature reduction is seen after adding Dominator® Coolant Boost?
Answer:
This indicates that the radiator is either undersized, has restricted or inadequate flow, or contains excessive scale/deposits that reduce heat transfer. In this situation, the radiator should be cleaned or replaced with a higher capacity, higher performance radiator.

18.
Question:
Will Dominator® Coolant Boost actively clean or remove existing scale and deposits in already fouled systems?
Answer:
No. Dominator® Coolant Boost is not designed as a flush.

19.
Question:
For long storage periods, should the coolant be drained and the system left dry?
Answer:
No. AMSOIL Dominator® Coolant Boost provides long term corrosion protection. Dominator® Coolant Boost contains a premium ingredient that chemically removes dissolved oxygen from any type of coolant, reducing the possibility of corrosion.

20.
Question:
If an owner’s manual suggests that a coolant system additive should not be used and may affect warranty coverage, will using Dominator® Coolant Boost void the warranty?
Answer:
No. Dominator® Coolant Boost exceeds the requirements set forth in ASTM D-4340 and ASTM D-2570 testing and will not void warranties. Dominator® Coolant Boost actually lowers chance of overheating and corrosive damage to the cooling system.

21.
Question:
Is Dominator® Coolant Boost compatible with stop-leak additives?
Answer:
There are no known compatibility issues between Dominator® Coolant Boost and stop-leak additives; however, AMSOIL does not recommend using stop-leak products with AMSOIL coolant products.

22.
