Coolant plays a crucial role in maintaining the stable operation of a truck engine. Using the correct type of coolant and replacing it periodically helps extend engine life, preventing overheating and damage. So, what type of coolant does a truck need? This article will provide you with detailed information about truck coolant, how to check and replace it, and important considerations.

What is Truck Coolant?
Truck coolant is not just plain water but a mixture of distilled water and ethylene glycol solution, along with some additives. Ethylene glycol lowers the freezing point, preventing the coolant from freezing in winter. Additives help prevent corrosion, scale buildup, and protect the cooling system. The type of coolant and mixing ratio depend on each vehicle type and operating conditions. What coolant a truck needs will be specifically recommended in the manufacturer’s user manual.
How to Check Truck Coolant
Regularly checking the coolant is crucial to ensure efficient engine operation. You can check it by:
- Observing the reservoir: The coolant reservoir is usually located in the engine compartment. Check the coolant level, ensuring it is between the “Min” and “Max” marks on the reservoir.
- Monitoring the temperature gauge: The temperature gauge needle at the “C” (Cool) position indicates a stable engine temperature. If the needle approaches the “H” (Hot) mark, it’s necessary to check and add or replace the coolant.
Truck Coolant Replacement Guide
Replacing coolant is a task that needs to be performed periodically. If you have experience and tools, you can do it yourself at home following these steps:
Step 1: Prepare tools: Clean water container, new coolant container, screwdriver, funnel, drain pan, flashlight, and gloves.
Step 2: Drain old coolant: Ensure the engine is completely cool. Open the reservoir cap, lift the vehicle, and locate the drain valve at the bottom of the radiator. Drain all the old coolant into the drain pan.

Step 3: Flush the reservoir: Pour clean water into the reservoir, close the cap tightly, and start the engine for about 3-5 minutes. Turn off the engine, let it cool down, and drain the clean water.
Step 4: Mix new coolant: Mix new coolant according to the manufacturer’s recommended ratio. Pour the mixture into the main reservoir and the expansion tank.
Step 5: Start and check: Start the engine, monitor the temperature gauge and coolant level. Add more coolant if necessary.
Step 6: Dispose of waste coolant: Pour the old coolant into a specialized container and dispose of it according to regulations.
When to Replace Truck Coolant?
Manufacturers recommend replacing coolant every 2-3 years or 40,000 – 60,000 km of operation. However, the replacement frequency also depends on operating conditions and the type of coolant used.

Causes of Truck Coolant Loss
Several reasons can lead to coolant loss:
- Leaks: The cooling system may leak at hoses, joints, or the radiator.
- Damaged radiator: Damaged radiator fins can cause coolant leaks.
- Cracked engine block: Coolant can leak into the combustion chamber due to a cracked engine block or a damaged cylinder head gasket.

Important Notes When Replacing Coolant
- Do not use tap water, well water, or bottled water to replace coolant.
- Only open the reservoir cap when the engine is completely cool.
- Do not mix different types of coolant.
- Use gloves and safety glasses when handling coolant.
- Follow the manufacturer’s instructions carefully.
Choosing the right type of coolant and replacing it periodically is crucial to ensure operating efficiency and extend the lifespan of your truck engine. If you are unsure about what coolant your truck needs, consult with experts or technicians at reputable garages.
