AMSOIL DOMINATOR® Coolant Boost

  • Provides effective heat transfer and enhanced corrosion protection
  • Reduces engine temps up to 25°F (13.8°C)
  • Helps vehicles warm up an average of 54% faster

Product Overview

Improves heat transfer for increased horsepower. Reduces engine temperatures. Radiator-safe. Helps prevent corrosion in high-performance racing applications. Compatible with all water sources, including distilled, bottled and tap water. Shortens warm-up time. Safe for use with antifreeze mixes.

REDUCES ENGINE TEMPS

  • Unlike other products, DOMINATOR Coolant Boost uses three surfactants, each designed to operate in a different temperature range, to increase liquid-to-metal contact.
  • Closer contact with metal parts increases the coolant’s efficiency in transferring heat away from hot engine parts and out through the radiator and fan.
  • Reduces engine temperature up to 25°F (13.8°C) for maximum efficiency.

FIGHTS DAMAGING CORROSION

  • Delivers outstanding corrosion protection for maximum cooling-system performance and life.
  • In industry testing, limited corrosion on the six metals most commonly found in cooling systems (copper, solder, brass, steel, cast iron and cast aluminum).
  • Excellent protection in racing applications using straight-water coolant.

FASTER ENGINE WARM UP

  • Proprietary tiered-surfactant technology helps engines warm up an average of 54% faster.
  • Helps the defroster begin working sooner and the cabin warm more quickly in passenger vehicles on cold days for maximum comfort.
