How Often Should I Change Engine Coolant?

Engine coolant is a vital fluid that helps to keep your car’s engine running smoothly. It circulates through the engine and absorbs heat, which is then dissipated through the radiator. Over time, coolant can break down and become less effective at absorbing heat. This can lead to overheating, which can damage the engine.

The frequency with which you need to change your engine coolant depends on several factors, including the type of coolant you use, the age of your car, and the climate in which you drive.

Type of Coolant

There are two main types of engine coolant: inorganic additive technology (IAT) coolant and organic acid technology (OAT) coolant. IAT coolant is the traditional type of coolant, and it is typically recommended for older cars. OAT coolant is a newer type of coolant that is less corrosive and lasts longer. It is typically recommended for newer cars.

IAT coolant should be changed every 2 years or 30,000 miles, whichever comes first. OAT coolant can typically last for 5 years or 100,000 miles, depending on the manufacturer’s recommendations.

Age of Your Car

As your car ages, its engine will become more susceptible to overheating. This is because the seals and gaskets in the engine can deteriorate over time, allowing coolant to leak out. As a result, it is important to change your engine coolant more frequently as your car ages.

For cars that are less than 5 years old, it is recommended to change the engine coolant every 2 years or 30,000 miles, whichever comes first. For cars that are 5 years old or older, it is recommended to change the engine coolant every year or 15,000 miles, whichever comes first.

Climate

The climate in which you drive can also affect the frequency with which you need to change your engine coolant. If you live in a hot climate, your engine will be more likely to overheat, so it is important to change the coolant more frequently.

For cars that are driven in hot climates, it is recommended to change the engine coolant every year or 15,000 miles, whichever comes first.

Signs That Your Engine Coolant Needs to Be Changed

There are several signs that may indicate that your engine coolant needs to be changed. These signs include:

The coolant level in the reservoir is low.
The coolant is discolored or rusty.
The coolant has a sweet smell.
The engine is overheating.

If you notice any of these signs, it is important to have your engine coolant checked and changed as soon as possible.

How to Change Engine Coolant

Changing engine coolant is a relatively simple task that can be done at home with a few basic tools. The following steps will guide you through the process:

Park your car on a level surface and allow the engine to cool down.
Locate the coolant reservoir and remove the cap.
Drain the old coolant into a drain pan.
Flush the cooling system with water until the water runs clear.
Add the new coolant to the reservoir.
Replace the cap on the reservoir.
Run the engine and check for leaks.

It is important to dispose of old coolant properly. Do not pour it down the drain or into the ground. Instead, take it to a local recycling center.

Conclusion

Changing your engine coolant is an important part of maintaining your car. By following the guidelines in this article, you can help to keep your engine running smoothly and avoid costly repairs.
