Buying Guide for the Best Coolant for Diesel Engine 2023
What is a Coolant for Diesel Engine?
A coolant for diesel engine is a liquid used to help regulate the temperature of the engine. It does this by absorbing heat from the engine and dissipating it into the surrounding air. Coolants can be either water-based or oil-based.
- Water-based coolants are typically made up of a mixture of water and glycol. Glycol is an organic compound that helps to increase the boiling point of the water, which in turn allows the coolant to better dissipate heat. Water-based coolants are typically used in engines that operate at lower temperatures.
- Oil-based coolants, on the other hand, are made up of a mixture of oil and water. The oil helps to lubricate the engine parts and prevent corrosion. Oil-based coolants are typically used in engines that operate at higher temperatures.
The type of coolant you use in your diesel engine will depend on the operating temperature of the engine. If you are not sure which type of coolant to use, consult your owner’s manual or ask a qualified mechanic.

Why is it Important to Use the Correct Coolant?
Using the correct coolant in your diesel engine is important for two main reasons. First, using the wrong coolant can lead to engine damage. Second, using the wrong coolant can void your engine’s warranty.
If you use a water-based coolant in an engine that operates at high temperatures, the coolant can break down and form deposits on engine parts. These deposits can lead to engine damage and decreased performance.
If you use an oil-based coolant in an engine that operates at low temperatures, the oil can thicken and form clogs. These clogs can restrict coolant flow and lead to engine overheating.
Using the wrong coolant can also void your engine’s warranty. Be sure to check your owner’s manual or ask a qualified mechanic to find out what type of coolant is recommended for your diesel engine.
Features of Coolant
Coolant should be able to protect your engine from corrosion, freezing, and overheating. It should also be compatible with the materials used in your engine’s cooling system.

Types Of Coolant for Diesel Engine
There are four main types of coolant used in diesel engines: water-based, oil-based, glycol-based, and air-cooled. Each has its own advantages and disadvantages, so it’s important to choose the right type for your engine.
- Water-based coolants
These are the most common type used in diesel engines. They’re typically made from a mix of water and antifreeze, and they’re effective at keeping the engine cool. However, they can also cause corrosion and scale build-up on engine components.
- Oil-based coolants
These are less common than water-based coolants, but they offer some advantages. They’re usually made from a mix of oil and water, and they don’t cause corrosion or scale build-up. However, they can be difficult to find and may require special ordering.
- Glycol-based coolants
These are the least common type of coolant used in diesel engines. They’re made from a mix of glycol and water, and they offer some advantages over water-based coolants. Glycol-based coolants don’t cause corrosion or scale build-up, and they’re less likely to freeze in cold weather. However, they can be more expensive than other types of coolants.
- Air-cooled coolants
These are the most unusual type of coolant used in diesel engines. They don’t use water or any other liquid but instead rely on air to keep the engine cool. Air-cooled coolants are less effective than other types of coolants, but they’re often used in high-performance engines where weight is a concern.
No matter which type of coolant you choose, it’s important to make sure it’s compatible with the materials used in your engine. Incompatible coolants can cause serious damage to your engine, so it’s important to choose the right one.

Frequently Asked Questions
What is the best coolant for a diesel engine?
The best coolant for a diesel engine is one that has a high boiling point and a low freezing point. This ensures that it can effectively dissipate heat from the engine, even in extreme conditions.
Can I use water as a coolant in my diesel engine?
No, you should not use water as a coolant in your diesel engine. Water has a much lower boiling point than coolant, so it will not be effective at dissipating heat from the engine. In addition, water can cause corrosion to the engine components, so it is not an ideal choice for use in a diesel engine.
Can I mix coolant with water?
Yes, you can mix coolant with water. However, you should only do this if you are using distilled water. This is because other types of water can contain minerals that can damage the engine components.
The ratio of coolant to water should be 50:50. This will give you the best protection for your engine, while still allowing the coolant to effectively dissipate heat.
Should I add extra coolant to my engine?
Yes, you should add extra coolant to your engine if it is running low. This is because the coolant level will drop over time, due to evaporation and engine usage.
If the coolant level gets too low, it will no longer be able to effectively dissipate heat from the engine. This could lead to overheating and serious damage to the engine components.
How often should I change my coolant?
The frequency with which you change your coolant will depend on the type of coolant you are using. Some coolants can last for up to five years, while others need to be changed every two years.
It is important to check the manufacturer’s recommendations to find out how often you should change your particular type of coolant.
What are the signs that I need to change my coolant?
There are several signs that you may need to change your coolant. Firstly, if the coolant level is low, you will need to add more. Secondly, if the coolant looks dirty or muddy, it may be contaminated and needs to be replaced. Finally, if your engine is overheating, this could be a sign that the coolant is not effective and needs to be changed. If you notice any of these signs, you should change your coolant as soon as possible.
What is the best coolant for my engine?
The best coolant for your engine will depend on the type of engine you have. For most engines, ethylene glycol coolant is the best choice.
However, if your engine is subject to extreme temperatures, you may need to use propylene glycol coolant. Be sure to check the manufacturer’s recommendations to find out which type of coolant is best for your engine.
Can I use tap water instead of coolant?
No, you should not use tap water instead of coolant. This is because tap water can contain minerals that can damage the engine components.
Instead, you should use distilled water or deionized water. These types of water do not contain any minerals, and they will not damage the engine components.
Can I add coolant to my engine while it is running?
No, you should not add coolant to your engine while it is running. This is because the coolant can enter the engine and cause damage. Instead, you should turn off the engine and allow it to cool down before adding coolant. Once the engine is cool, you can safely add coolant to the reservoir.
If you are looking for the best coolant for diesel engine, 2022 is going to be a great year.
