Fluid Flush: How Often Should You Get Yours Done?

We change our oil, check our tire pressure, change our wiper blades, and check our fluid reservoirs. But, how often do we flush our fluids? Wait, do I even need a fluid flush? I thought checking the reservoirs & maintaining the levels was enough?

Although fluid flushes don’t have to be done often, you still need to flush them eventually. Therefore, when your mechanic looks over your car and recommends flushing the transmission fluid… he might not just be selling you something.

Fluid Flush: How Often Should You Get Yours Done?

Of course, as I’ve stated in almost all of my articles, if you want your car to last awhile you need to keep it well maintained. For the most part, a fluid flush does not happen every 5,000 miles like changing your oil. It all depends on how old your car is, how many miles are on it, how it was driven/has been driven, and what the fluids look like currently.

There are a couple different fluids that can be flushed, which we will get to below. Some require a fluid flush more than others, so after you read this article, refer to your owners manual & check when each fluid needs to be flushed. Then, mark the miles in your maintenance log so you can keep track of when your next fluid flush will be & with what fluid.

Types of Flushes:

  1. Transmission Fluid Flush
  2. Coolant Fluid Flush
  3. Brake Fluid Flush
  4. Fuel System Flush
  5. Power Steering Flush
  6. Radiator Flush

For the most part, all of these fluid flushes should be performed once your vehicle hits around 75,000 miles. You can tell if you check your reservoirs often. You will see slight changes in color. Or, you’ll start noticing issues with your vehicle performance, but hopefully, you can flush them before anything serious happens.

What Is A Fluid Flush?

Since we now know the types of fluid flushes your mechanic can perform to help enhance the life of your vehicle, let’s talk about what an actual flush is. Similar to changing your oil, a fluid flush is beneficial because, over time, your car fluids will start to deteriorate. If you don’t flush them eventually, and by eventually I’m talking about 70,000+ miles, they will continue to deteriorate & clog up; just like your motor oil would do if you didn’t change it frequently.

How is it done? Your mechanic will simply pull the plugs on the reservoirs from the top & bottom and clean out the reservoirs/tank. Then, once everything is cleaned out they will plug everything back up & add new fluid. Pretty simple task. Sometimes the reservoirs are hard to reach depending on your vehicle and could be costly (like your transmission fluid), but you should only be flushing fluids once every 70,000+ miles. Your owners manual will tell you when you should get a flush done, so always refer to that if you are still unsure!
