Why coolant choices are important when servicing an engine

The majority of drivers don’t think about engine coolant. It’s just another fluid that may be checked during an oil change. Engine coolant serves three important functions: it reduces the freezing point of the cooling system in the winter, raises the boiling point in the summer, and protects the engine and cooling system from rust and corrosion all year. If your truck cooling system isn’t topped off or replaced with the right coolant, it can create expensive complications.

The essential component of coolant is to transfer heat and protect engines from freezing or boiling. Because heat can only be transported properly while a liquid is present in the system, it’s critical to maintain the appropriate coolant level.

Furthermore, when coolant boils, the vapors created do not transfer heat efficiently, which means that if the coolant isn’t in contact with metal surfaces to carry the heat away, the engine can overheat. Some of the new trucks have tight engine compartments with reduced air flow, 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 the engine.

What Kinds of Engine Coolant Are There?

To effectively maintain the vehicle’s cooling system and safeguard the engine from harm, many modern autos require improved engine coolants. Today, there are three major kinds of engine coolant used by automobile repair providers:

  • Inorganic Additive Technology. This characteristic green-colored coolant has been used to preserve cooling systems for decades, although it is rarely utilized as factory fill in current automobiles. One reason is that its additives deplete quickly, requiring it to be replaced more regularly, generally every two years or 24,000 miles.
  • Nitrited Organic Acid Technology: Extended Life Coolant (ELC) does not require a supplement additive to achieve extended service intervals.

The ELC antifreeze/coolants use organic acids (organic additive technology), nitrite and/or        molybdenum as part of their inhibitor package and are referred to as Nitrited Organic Acid   Technology (NOAT) antifreeze/coolants.

  • Organic Acid Technology. OAT coolants are incompatible with other types of coolants and are frequently necessary for automobiles made by General Motors and several other automakers. OAT coolants are commonly orange, yellow, red, or purple and should be replaced after five years or 50,000 miles.
  • Hybrid Organic Acid Technology. HOAT coolants are generally orange and yellow in color and are found in Chrysler and Ford vehicles. They provide the perks of both IAT and OAT coolants. Although some manufacturers stipulate periods as long as 10 years or 150,000 miles, OAT coolants are normally replaced every five years or 50,000 miles.
  • Hybrid and Electric Vehicle Cooling Systems. The battery pack in most hybrid and electric vehicles is cooled separately. In such systems, just coolants that fulfill the automakers’ specs are used.

Why Is Getting the Adequate Engine Coolant Really Important?

Engine coolants in older automobiles were primarily brass, rubber components, and cast iron, and that they were all very much the same. Parts consisting of copper, silicon, nylon, steel, magnesium, and aluminum alloys are now used in automotive cooling systems.

The sort of coolant your vehicle requires currently varies by year, make, model, engine, and even place of manufacture. With so many variables at play, car owners must choose which engine coolant is appropriate for their vehicle.

What Are the Implications about Using the Incorrect Coolant?

Corrosion and component degradation can have long-term consequences if you don’t have the right coolant in your system. They can be latent, which means corrosion damage, deposits, and clogging might take up to a year to manifest.

Drivers frequently misdiagnose this as a radiator failure rather than admitting that the wrong coolant was used. You may seek advice from the local truck mechanic. A faulty coolant system is likely to be the source of a heavily corroded radiator or one that is full of clogging deposits.

Since coolant-related problems occur inside the engine, you may not recognize the extent of the damage unless you inspect the cooling passageways and internal heat-transfer surfaces of the engine, or when you hire a truck mechanic to handle things properly.

When Should I Replace My Vehicle’s Coolant?

As engine technology advances, the length of time between coolant changes has continuously increased.

Changing your coolant every two years was the normal recommendation just two decades ago. Then, around a decade ago, that time period was extended to five years. The cooling systems in many modern vehicles are designed for even longer periods before requiring coolant replacement.

Various materials of construction, different operating situations, different variable flow rates, different peak temperatures and pressures, different elastomers, different non-metallics and gaskets, you pick it—every vehicle is different.

But they all have one thing in common: they need to be safeguarded. Your vehicle’s original equipment manufacturer (OEM) does considerable testing to decide which fluids, including coolant, should be used in the systems they’ve designed. And, if you ever want fleet truck repair, you must seek guidance from specialists.

Maintenance and Repair of Truck Cooling Systems

Your truck may be very reliable, but it, like any machine, may incur serious and irreversible damage if it overheats. The cooling system of a truck engine is critical to the smooth running of your truck and your business. If your commercial vehicle’s ‘Engine Temperature’ light comes on or the temperature gauge reads ‘high,’ you should take it to a skilled truck mechanic as soon as possible to avoid a breakdown and engine damage. Even better, have your truck’s cooling system maintained by a skilled mechanic before it has to be repaired.

Conclusion

Having your repairs and maintenance handled at OKTruck Repair is an excellent method to obtain the proper coolant to keep your vehicle on the road and performing smoothly.
