Antifreeze, also known as engine coolant, is a colored liquid mixed with water to help regulate the engine during a very cold weather. As the temperature outside changes from hot to cold, coolant is pumped throughout the engine block to maintain an even temperature. In addition to preventing the water in the car engine’s cooling system from freezing, antifreeze also has multiple capabilities to help a car maintain its best performance.
Antifreeze can raise the boiling point of the engine coolant to prevent it from overheating. It can also protect the engine from corrosion and prevent scales from building up.
When it comes to antifreeze, there are different types to choose from. There are concentrated forms and ready mixed. If you buy the concentrated form of antifreeze, you will need to dilute it with water before you use it. This would be 50% concentrated antifreeze with 50% water. But this can differ, so make sure you check the instructions first. Ready mixed antifreeze, on the other hand, can be used in your vehicle for top-ups and replacements straightaway.
Why you should check antifreeze regularly
Changing antifreeze regularly provides numerous benefits to your cooling system. It is crucial to maintain your cooling system, just like any other component of your car, which is why it’s advisable to change your antifreeze regularly.
Here are the top benefits of changing your engine coolant:
- The new antifreeze contains additives that can lubricate a car’s water pump, which can help prolong the life of your water pump.
- The additives in the new antifreeze can also help prevent rust from building up in the water pump, enabling the cooling system to work effectively.
- By changing your engine coolant, you will eliminate rust and scale deposits that can build over time. It is crucial to get rid of these deposits since they can cause damage to the whole of your cooling system.
- Over time, the old antifreeze loses its anti-corrosive properties, allowing contaminants to build up in the cooling system. Changing your engine coolant can completely clean these particles from the system.
- When changing your antifreeze or during air conditioning repair, you will receive an inspection of your entire cooling system, including the radiator, thermostat, and all the hosts and belts. This is absolutely incredible it can help you identify leaks and other potential problems.
- Finally, changing your antifreeze can help your old antifreeze from becoming acidic. This is important because once your antifreeze starts becoming acidic; it will break down and can significantly damage the bearing in the water pump and the rubber hoses.
How often should you change your antifreeze?
How often you replace your antifreeze does vary slightly depending on your vehicle manufacturer. However, the general rule is to check and replace it at least twice a year. That’s before summer and winter. You can also replace the antifreeze after at least 30,000 miles. Again, if you notice any signs of rust or discoloring, you should replace your antifreeze right away.
