Diesel coolant is essential for proper vehicle operation. Coolant circulates within an engine to absorb and dissipate heat, and a diesel engine requires the right type of coolant to prevent engine overheating, freezing and potential failure. Engine coolant for diesel trucks and construction equipment contains additives to protect engine components from corrosion, cylinder cavitation and pitting. Diesel antifreeze further safeguards the engine by preventing freezing.

What Is Diesel Coolant?
Diesel engine coolant is a liquid that helps regulate an engine’s temperature. It works by circulating throughout an engine, absorbing and dissipating the heat the engine produces as it operates. The heat absorption and dissipation prevent the engine from overheating in the summer and freezing in the winter so the vehicle can run safely and effectively.
Coolant for diesel engines is slightly different from the coolant gasoline-powered vehicles use because it contains special additives to protect vehicles.
Importance of Diesel Engine Coolant
Diesel engines require more attention than other vehicles, and coolant is especially important if you drive a vehicle with a diesel engine. Using the proper coolant is crucial for safe and reliable vehicle operation, and ensuring your diesel vehicle maintains the correct coolant levels offers several benefits:
Proper Operation
Diesel engines are more prone to overheating than gasoline-fueled vehicles. Coolant is crucial to preventing an engine from overheating or freezing, and it helps prevent your car from breaking down. Using the right coolant and maintaining proper levels keeps your vehicle operational and on the road with fewer interruptions.
Engine Component Protection
Since coolant dissipates the heat an engine produces, it protects critical components from damage. Diesel engine coolant also carries additives such as anti-foaming agents and corrosion inhibitors to protect your vehicle from cylinder pitting and cavitation.
Cavitation Prevention
Smaller, dry-sleeve engines and larger, wet-sleeve engines require coolant, but specific diesel engine coolant is especially essential for wet-sleeve engines. A wet-cylinder engine’s sleeve contains the engine’s piston, and the sleeve has direct contact with the coolant in its system, allowing it to dissipate more heat. Since the coolant comes in direct contact with a wet-cylinder engine’s iron sleeve, it is more susceptible to cylinder wall cavitation, and the engine has specific coolant requirements.
Cavitation describes when small bubbles form behind an engine’s cylinder walls due to the walls vibrating against the engine’s piston, and diesel coolant is a heavy-duty solution containing additives to prevent cavitation.
Choose the Right Coolant
Diesel engines require adequate lubrication to operate smoothly, so choosing the correct coolant is crucial. The best type of coolant for a diesel engine is one with a high glycerol level because it provides the most effective lubrication. Most coolants contain 30% to 70% glycerol, but the best coolants are up to 95% glycerol.
Understanding the different types of coolants can help you choose the best option for your vehicle.
IAT
Inorganic acid technology (IAT) coolant is popular for its cost-effectiveness. Its quality is lower than other options, but owners of older cars tend to use it due to its lower cost.
OAT
Organic acid technology (OAT) coolant is a newer, more refined type of antifreeze than IAT. It’s made with ethylene glycol, and it requires few replacements. With OAT coolant, you can drive up to 150,000 miles or five years before replacing your antifreeze. OAT is a popular option in Europe because its composition provides the best protection for European cars.
HOAT
Hybrid organic acid technology (HOAT) combines OAT and IAT coolants for a cost-effective but high-performance option for drivers. HOAT is the newest coolant solution, allowing you to drive your vehicle for 150,000 miles or three years before replacing the antifreeze. Automotive professionals trust this new solution for diesel vehicle maintenance.
How to Properly Replace Your Coolant
While most high-quality coolants can last up to 150,000 miles or three to five years, replacing them more frequently is best for your vehicle’s operation and life span. Your control board can indicate when it’s time to replace your antifreeze, but you should also inspect your engine periodically to check coolant levels.
The best time to check coolant levels is when the weather starts to shift. We recommend inspecting your coolant reservoir tank during the end of summer or the beginning of fall before the colder weather begins to approach, and you should recheck it toward the end of winter and the beginning of spring before summer temperatures begin to rise.
You can locate your coolant reservoir tank by reviewing your vehicle manufacturer’s manual. Once you find the diesel antifreeze reservoir, look at the coolant’s level within the tank. If it seems low, you should replace it to ensure you have an adequate amount for the upcoming season. You can also seek assistance from a professional mechanic to ensure you maintain it properly.

The technology that goes into deriving diesel from crude oil has come a long way. The advent of ultra-low sulfur diesel and biodiesel are two great examples of how the fuel developed over the decades. Additionally, the invention of diesel particulate filters and the development of engineering prowess that made diesel engines more fuel efficient also add to the discussion when the topic is the turbocharged diesel engine’s journey since its inception.
The applications of turbocharged diesel engines are wide and varied. The primary application of turbocharged diesel engines is in semi-trucks and pickup trucks. Diesel engines are bulletproof however, they are not invincible. Semi-truck and pickup truck drivers need to remember certain tips that would allow them to prolong the lives of their vehicle’s turbocharged diesel engines.
Some of those tips are mentioned in the sections below.
#1 – Let the engine idle for a few minutes
Always ensure that you are letting your turbocharged diesel engine vehicle run for a while in a bid to achieve optimal operational temperature before stepping on the throttle and driving off.
The reason is simple. When the engine is allowed to run for a while, the internal parts of the machine get properly doused in engine oil. This ensures premature wear of engine internals is kept at bay.
Then there is the objective of prolonging the life of the vehicle.
One of the primary challenges of fleet management is to ensure that commercial vehicles last for a long time. This objective can be easily achieved by installing real-time fleet tracking devices in vehicles with turbocharged diesel engines. Furthermore, an affordable fleet tracking system also lets heavy-duty vehicle drivers gauge their performance as drivers. Gauging driving parameters helps drivers learn ways to prolong the life of their turbocharged diesel engine-equipped vehicle by several folds.
It is as simple as that!
#2 – Diesel additives are your vehicle’s friends
Diesel additives are your vehicle’s turbocharged diesel engine’s friends. They are not only good for the turbocharger attached to the engine but also for the engine as a whole. Oil additives keep the heat-related damages sustained by the turbocharger and the engine internals to a bare minimum.
Additionally, fuel additives prevent diesel fuel from solidifying when the ambient temperature drops below freezing.
#3 – Please change the engine oil and diesel fuel filters on time
Diesel engine goes through a lot. They are put through a lot of stress especially when the vehicle is used to haul trailers loaded with oversized cargo. Additionally, turbocharging a diesel engine also means the internal components of the machine will be regularly subjected to hellish operational temperatures.
Excessive stress and operational temperatures mean that the engine oil inside a turbocharged diesel unit will need to be changed frequently. Ensure that the oil is changed as per OEM-specified mileage/interval. Furthermore, ensure that the diesel fuel filter of your turbocharged diesel engine is also changed on time alongside its intake filter so that the machine can ‘breathe’ and ‘drink’ normally.
If you are unable to track the service intervals, rely on fleet telematics offering fleet route optimization feature. With route optimization, as a commercial vehicle driver or as a commercial vehicle fleet manager, you will be able to save a lot of money especially when it comes to fleet vehicle maintenance.
# 4 – Use the right coolant for your turbocharged diesel engine
Always ensure that you are pouring OEM-specified coolants into your vehicle’s turbocharged diesel engine. The reason is simple. Pouring the wrong coolant type in your vehicle’s turbocharged diesel engine can cause irreversible damage to its cooling system due to unwanted chemical reactions between the active ingredients of the ‘wrong’ coolant with the internal metallic surfaces of the system.
In case you are stuck at a place where your engine’s coolant levels are low and the ‘right’ coolant is not available, you can always pour some purified drinking water. However, as soon as you enter a locale where the ‘right’ coolant is available, pour the same into your vehicle’s engine cooling system. Leaving excess water in the engine’s cooling system is hazardous especially if you drive your turbocharged diesel engine-equipped vehicle at a place where the temperature drops below freezing.
Additionally, start using fleet trackers so that you can plot a route that has multiple service stations that also sell spare parts. Additionally, connected vehicle solutions can also help you ensure your vehicle is maintained at OEM-specified intervals.
Diesel engines are robust but only when you take care of them
Taking care of your vehicle’s turbocharged diesel engine is pretty easy, to be honest. To sum up, the tips mentioned in the above sections of this post, let’s begin with the fact that you should not rev the engine just after turning it on. This will ensure that every movable part in your vehicle’s engine is doused in engine oil.
Secondly, do not forget to use diesel fuel additives. The reason is simple. Diesel fuel additives keep the entire diesel fuel injection system clean. Additionally, diesel fuel additives keep the fuel from solidifying when the ambient temperature drops below freezing.
