Fluid Flushes

Your car has several systems that use fluids that need to be changed at various service intervals. These intervals are established by your manufacturer and will vary from vehicle to vehicle. As you will learn, each of the fluid types has different properties based on their desired function.

Here are the types of fluid flushes that we perform at Knebles Auto Service Center:

Brake Fluid Flush – Brake fluid is the hydraulic fluid used to create the pressure to activate the braking system. It is designed to perform at high temperatures without losing its chemical properties, however, over time, it should be replaced.

During a brake fluid flush, fresh brake fluid is forced through the braking system at high pressure and bled from each caliper or wheel cylinder until the fresh fluid starts to flow out. The system is also bled to ensure that any air that entered the system is released, as air will minimize the pressure in the braking system making it inefficient.

Coolant Flush – Antifreeze is the coolant used in your car to keep the engine from freezing in the winter and from overheating in the summer. Over time, the coolant loses its anti-corrosive, antifreeze, and anti-boil properties, and must be replaced.

During a coolant flush, water is used at high pressure to expel the coolant from the cooling system. Draining the radiator alone does not remove the coolant from all of the components which is why the flush is necessary. The flushing process also removes any sludge, buildup, or debris from within the cooling system.

Power Steering Fluid Flush – Over time oxidation and heat cause the power steering fluid to break down and lose its chemical properties. As this occurs, the fluid can cause damage to internal seals and ultimately the power steering pump, steering unit, or other components. For this reason, we recommend flushing this fluid out periodically (per manufacturer’s recommendations) to replace it with fresh fluid that will perform as designed.

Transmission Fluid Flush – An automatic transmission requires fluid to operate, and as the internal components of your transmission wear, the debris left behind can be transported to other parts of the transmission and cause valves or solenoids to stick or not operate properly. This can result in a wide range of transmission malfunctions leading you to believe that your transmission is failing. It is recommended to periodically flush the fluid to proactively avoid these issues. Some transmissions have replaceable filters and others have screens that need to be cleaned during the flush process.

A manual transmission does not use fluid to operate, but rather to keep the moving parts lubricated. Fluid in a manual transmission needs to be replaced less frequently than that of an automatic transmission.

Frequently Asked Questions About Fluid Flushes:

How I Often Do I Need to Flush My Brake Fluid?

A good rule of thumb for this is every 2 years or 30,000 miles, however, we recommend checking your owners manual to find out what is recommended for your specific vehicle.

How I Often Do I Need to Flush My Coolant?

The timeframe for this varies widely by manufacturer, so we recommend checking your owner’s manual to find out what is recommended for your specific vehicle. If you notice any rust, discoloration, or debris in your cooling system that would be an indication that a flush is overdue, or it may be a sign of another problem in the cooling system.

How I Often Do I Need to Flush My Power Steering Fluid?

There is a wide range of manufacturers’ recommendations for replacing power steering fluid, so we recommend checking with your owner’s manual. If you check the fluid and it appears dark or has a burnt smell, that is a good sign that the life of the fluid is close to – or has come to – an end.

How I Often Do I Need to Flush My Transmission Fluid?

The fluid in an automatic transmission will need to be replaced more frequently than that of a manual transmission. The service intervals can range from 30,000 to 100,000 by the manufacturer. If your automatic transmission fluid has a dark appearance or burnt smell, that is an indication that the fluid is old and may need to be replaced, however, it can also be a sign of internal wear and it should be assessed by one of our ASE Certified Technicians.
