Why Should You Get a Flush?

benefits of a flush


It doesn’t really matter who you ask, it’s important to flush in all situations, in some cases it may be best to flush twice. We understand that there are times where you just want to cleanse from a tough week at work. Believe it or not, we think that your car could benefit from a cleanse too, which is why we suggest giving your car the flush it deserves! We’ve prepared this guide for you to highlight the importance of a brake flush and a coolant flush so that your car stays happy for many years to come.

What is GAP Insurance?

GAP usually has a long definition, but all that GAP entails is additional insurance on a car that covers the vehicle’s value between the amount owed and what the vehicle is worth. That may have still been a bit confusing, so we put together an example to explain the concept of GAP insurance even further. Let’s imagine you purchase a vehicle for $25,000 and finance the entire amount over a 60-month term. Then let’s say 6 months later your vehicle gets totaled by a fallen tree (Seems overly simplistic, but you get the idea). With this accident, your insurance company would pay out the car’s value which is in this case $15,000. Unfortunately, this would mean that you probably still owe about $24,000 on your loan. With GAP insurance, you may receive the $9,000 difference in order to avoid losing any money in the event of an accident. See below for a figure showing this example!


brake fluid flush

When considering replacing your brake pads and rotors, it may be a good idea to also consider performing a brake fluid flush. Brake fluid could have the tendency to become contaminated with small particles that ultimately reduces the boiling point of the brake fluid. When your fluid boils faster, it can cause your fluid to vaporize which in turn negates the hydraulic braking force. Some people may think that even a small reduction won’t make a difference, but brake failure could be the difference of an inch that could avoid a catastrophic accident or collision. Next time you swap out your brakes be sure to check if you need to flush your brake fluid to ensure it’s clean and that it will brake optimally and avoid long term damage to other braking components.



Since we mentioned the occasional importance of a “double-flush” we’re going to get into a secondary flush that is often overlooked and that is a coolant flush. Engine coolant is a fluid also known as antifreeze that is a heat transfer fluid designed to pull excess heat from the engine. While an engine generates a lot of heat, the coolant helps maintain that engine cool, it stops the engine’s water from boiling and it prevents rust and corrosion on metal and plastic parts. There are at least six benefits to a coolant flush, but it would be best if we just summarized the overall benefit. In summary, a coolant flush will remove rust and scale deposits that can build up and damage your entire cooling system. The new coolant will provide you with the additive and lubrication necessary to keep your engine running at optimal temperatures.


We have discussed two important flushes so far, but we thought it would be fitting to include an honorable mention in the mix. The honorable mention in this scenario is a transmission flush. When considering the fact, your transmission is what allows your vehicle to shift through gears to get around town. The transmission fluid inside of it is what keeps the gears and components properly lubricated for a smooth ride. Ultimately, the fluid allows the transmission to maintain regulated temperature and all parts moving without harmful friction.



Power steering is probably one of the most hostile of all the fluids when it needs replacing. The fluid tends to develop a texture that resembles that of a sandy texture. What this does is cause an increase in friction which then wears the seals and gears in your power steering system. If these seals are messed up, then you are now in risk of having power steering failure which is what allows you to steer your vehicle freely. The power steering system is completely sealed so leaks should not occur easily. If you notice that your fluid level is low then it is imperative you bring it in to Bill Luke to be checked by our technicians as soon as possible. By replacing your power steering every 75,000 miles you ensure your components stay healthy.


It’s amazing what you can accomplish when you flush on a regular basis. It allows you to rid your vehicle of any contaminants and particles that may be lingering. These contaminants are what keep your vehicle from performing the way it was intended to.  If you find yourself realizing that your vehicle has probably never received a flush, then it may be a good idea to get it into the service department asap!

Are car flushes necessary?

Vehicle flushes are necessary depending on the need and maintenance schedule of your vehicle. A vehicle flush is part of the preventative maintenance for your vehicle. For the most part, a vehicle flush isn’t too common, but most manufacturers require it as part of their regular maintenance. Instances where a flush would be necessary is if there is a system failure that contaminates the fluid with debris. Other instances would be that components in the systems have become clogged or stuck with debris from buildup and other contaminants.

How much does it cost to flush fluids in my car?

The cost to flush your fluids varies depending on the vehicle you own. However, the typical price for the usual flushes are as follows: Coolant – $190, Brake – $160, and Transmission $400.

How often should I flush the fluids in my car?

While we recommend you consult with our service technicians and or your owner’s manual in your car. The recommended time to flush your fluids is at 75,000 miles for your transmission.

What happens if I don’t change my brake fluid?

If your brake fluid isn’t flushed or swapped out as recommended by the manufacturer you run the risk of moisture contamination in your brake reservoir. This in turn may lead to poor braking performance which could be catastrophic.

How often should you flush power steering?

Power steering is also a fluid that may vary on the timeline depending on the vehicle and what the manufacturer for that vehicle recommends. Typically, you want to consider flushing your power steering fluid every 50,000 miles.
