How Often Should You Change Coolant

Coolant is an important component of any car, and it’s essential that you change it regularly. In fact, most automakers recommend that you change your coolant every 7,500 miles. But why? What are the benefits of changing your coolant? And how often should you be doing so? In this blog post, we will answer these questions and more. We will also provide a step-by-step guide on how to change your coolant in your car. So read on to learn everything you need to know about this important component of car maintenance.

What is Coolant and What Does It Do?

Coolant is a fluid that circulates inside your car to keep the engine cool. The fluid also helps lubricate the engine and transfer heat from the engine to the exhaust. Over time, coolant can thin and eventually become ineffective. When this happens, your car may not start or run as well. Regularly checking your coolant level and replacing any excessively thin or expired coolant are important steps in keeping your vehicle running smoothly.

How Often Should You Change Coolant?

Changing your car’s coolant is an important part of maintaining its cooling system. Coolant is a liquid that helps keep the engine running smoothly. It also protects the engine from overheating and makes sure that the pistons and other parts don’t get too hot.

The purpose of an auto manufacturer’s warranty is to protect drivers against Manufacturer Defects, which are conditions in your vehicle that cause it not to conform to the expected performance or function of a vehicle. In order to qualify for Manufacturer Defect Protection, your car must have had its Factory Authorized Service completed within 12 months of when the defect occurred, and you must provide proof of service completion.

When Should You Change Your Coolant?

When it comes to your car’s cooling system, you should change your coolant every 7,500 miles. This means that if your car is 11 years old, it should be changed at the 10-year mark. And make sure to use a quality product like Pennzoil or Redline; using a knock-off will only result in poor performance and potentially expensive repairs down the road.

How do you Know If You Need to Change Your Coolant?

If your car has an automatic transmission, the fluid will be changed by the manufacturer at around 7,500 miles. If you have a manual transmission, or if your car has over 150,000 miles on it, you should change the fluid every 3 to 4 years. The fluid is a mixture of water and antifreeze, and it needs to be replaced because it can corrode the internal components of your car.


If you’re running an engine that uses coolant, it’s important to make sure you change it regularly. Over time, the coolant will break down and become less effective at preventing your engine from overheating. If your engine starts to overheat, changing the coolant can help reduce the damage that might be done.
