WHY THE CHOICE OF COOLANT IS IMPORTANT FOR AN ENGINE? PART ½.
Most drivers don't think about engine coolant. It's just another fluid to check during an oil change. Engine coolant has three important functions: it lowers the freezing point of the cooling system in winter, raises the boiling point in summer, and protects the engine and cooling system from rust and corrosion throughout the year. If your truck's cooling system is not topped up or replaced with the correct coolant, it can lead to costly complications.
The most important component of coolant is to transfer heat and protect your engine from freezing or boiling over. Since heat can only be transferred normally when there is fluid in the system, it is very important to maintain proper coolant levels.
In addition, when the coolant boils, the resulting vapors ineffectively transfer heat, which means that if the coolant is not in contact with metal surfaces to dissipate heat, the engine can overheat. Some newer trucks have tight engine compartments with a reduced airflow, putting them at risk of overheating in a short time if they don't have a properly functioning cooling system.
Coolant also protects metals and non-metallic elastomers such as rubber and plastic components in the cooling circuit and engine.
What kinds of engine coolant are there?
To effectively maintain a vehicle's cooling system and protect the engine from damage, many modern autos need improved engine coolants. Today, there are three main types of engine coolants used by truck repair shops:
• Inorganic Additive Technology
• Nitrited Organic Acid Technology
• Organic Acid Technology
• Hybrid organic acid technology
• Cooling systems for hybrid and electric vehicles
