These companies offer quality used cars and car-related services to residents of Springfield, Missouri, and the surrounding areas. Christopher King offers a variety of automotive repair and maintenance services through Queen City Motors service, one of which is coolant flushing.
Engine coolant protects the engine from rust and corrosion. The coolant drops the freezing point of the cooling system in the winter season and raises the boiling point during the summer months. There are three different types of coolants: IAT, OAT, and HOAT. IAT is an inorganic additive technology coolant. This is the classic green-colored coolant. The additives in this coolant will deplete over time. This kind of coolant will need to be replaced every two years or 24,000 miles. Compared to other coolants, this kind of coolant is more effective against engine corrosion but it does have to be replaced more often.
OAT is organic acid technology. This is the required coolant for General Motors vehicles and comes in a variety of colors. Replacement is at 5 years or 50,000 miles. This kind of coolant lasts longer than inorganic coolant and works better with newer engine materials such as aluminum.
HOAT is hybrid organic acid technology and comes in orange and yellow. This coolant is typically found in Ford and Chrysler vehicles. Replacement of this kind of coolant could be as long as 10 years or 150,000 miles. This coolant is meant to combine the protective qualities of inorganic coolants with the longer replacement requirements of organic coolants.
