coolant flush

It’s no surprise that the engine creates a lot of energy and heat to keep your vehicle in motion. The purpose of the cooling system is to make sure the engine stays cool. However, without proper maintenance or a coolant flush, your cooling system could malfunction. This has the potential to cause an overheated engine. In conclusion, in this article, we’ll talk about how coolant flushes help prevent this from happening. We’ll also discuss when you need to get this done.

How does the cooling system work?

Without the cooling system, the heat produced by the engine could cause a total malfunction. Luckily, the cooling system keeps the heat under control to prevent catastrophe. The cooling system is made up of the following:


  1. Thermostat
  2. Temperature sensor
  3. Water pump
  4. Pressure cap and reserve tank
  5. Intake manifold gaskets
  6. Head gaskets
  7. Heater core
  8. Hoses
  9. Bypass system
  10. Radiator
  11. Radiator cooling fans
  12. Freeze plugs


The cooling system also contains coolant, also known as antifreeze. Similarly, this liquid is transported throughout the engine to help it stay cool.

What is a coolant flush?

Over time, rust particles flake off your engine parts and contaminate the coolant. A coolant flush is done to remove the polluted coolant and replace it with fresh fluids. A cleaning solution is also circulated to help remove excess debris. There’s a big difference between topping off the coolant and having the coolant flushed. Topping off is done to ensure there’s enough liquid in the system for optimal performance. The purpose of a coolant flush is to replace all antifreeze in the system.

Why is it important to get my coolant flush done?

Regular coolant flushes have many advantages. For one thing, they remove harmful contaminants from your coolant. These particles can clog the thin tubes in your radiator and heater core, causing your engine to overheat. Coolant flushes also help the water pump. Keeping debris out of them and making sure they stay lubricated helps the water pump to last longer. However, another factor to consider is the acidity of the antifreeze. If it’s not flushed out and replaced periodically, the antifreeze can become too acidic, which is damaging to the engine. Additionally, antifreeze loses its anti-corrosion properties as it ages. This makes it less effective. After that, regular coolant flushes help lengthen your engine’s lifespan and keep everything well-maintained.

How often does a coolant flush need to be done?

Not all coolants are the same. Some last up to 2 years, and others last as long as 5 years. It’s always best to consult your dealership or owner’s manual for specifics on maintenance for your vehicle. Additionally, our certified professionals can help you figure out when it’s time for your coolant flush.

We suggest a complete cooling system inspection at least every two years. In addition, this examination should include the following:

  1. System pressure level check
  2. Pressure test
  3. Thermostat check
  4. Visual inspection of all cooling system parts
  5. System power flush and coolant refill
  6. Internal leak check
  7. Engine fan test

Everything You Need to Know About Taking Care of Your Brake Fluid

Brake fluid is unassuming. It’s just a liquid, right? Wrong. Without it, your brakes couldn’t
operate, and your engine would rapidly corrode. Today, we’ll discuss the role of brake fluid and
why it’s needed. We’ll also talk about some steps you can take to care for your brake fluid.
Let’s dive in.

What is Brake Fluid and why is it important?

Brake fluid is hydraulic and incompressible. That means it moves through the enclosed braking
system under pressure. This pressure, along with the fact that brake fluid can’t compress, creates
force. This force causes the calipers to fasten onto the rotors, bringing a moving vehicle to a
stop. Without brake fluid, there would be no force. It’s one of the most vital components of the
braking system.

As you know, engines produce a lot of heat. Brake fluid needs to have particular properties to
stand up to high temperatures. One property of brake fluid is its high boiling point. This stops it
from vaporizing, which would cause the brakes to fail. Additionally, brake fluid can keep a
constant viscosity, regardless of exposure to hot or cold temperatures. Viscosity is important
because brake fluid has to flow smoothly throughout intricate engine parts. Having a constant
viscosity helps the brake fluid travel with ease.

There are a few different types of brake fluid, but most of them are glycol-ether-based. This type
of fluid is hygroscopic, meaning that it can absorb fluid from the atmosphere around it. Since
brake fluid can absorb fluid, it contains some water. But, too much water can cause problems for
your system. For one thing, it can damage metal engine parts, leading to faster corrosion.
Additionally, it can lower the boiling point of the brake fluid. This could cause decreased
stopping ability. To avoid these problems, get your brake fluid tested and replaced when with
clean fluids as needed.

How often does brake fluid need to be changed?

Not all brake fluids are the same. How often your brake fluid needs changing depends on the
type you have in your vehicle. Your owner’s manual may have some information on this as
well. Generally speaking, we recommend a full brake fluid flush and replacement every year or

While we’re talking about routine maintenance, it’s also a good idea to get your brake fluid
tested for moisture. Since too much moisture is harmful, this can help you decide if you need to
replace the fluid altogether.

What are some signs my brake fluid needs to be changed?

The best way to figure out the status of your brake fluid is by looking at it. As it ages, brake
fluid changes in appearance. Brand new brake fluid is usually clear or amber-colored. The
longer it’s in your engine, the darker it becomes. You’ll know it’s ready to be replaced if it looks
sludgy and dark brown. If your fluid doesn’t need replacing yet, check its levels. It’s normal to
see a small decrease in brake fluid, but this can be problematic if it’s a regular occurrence.
Losing lots of fluid is often the sign of a leak or another issue needing maintenance.

Transmission Fluid: Why It’s Important and How to Take Care of It

Everyone knows the importance of routine oil changes, but another fluid often gets overlooked. That’s your transmission fluid. Today, we’re discussing everything you need to know about transmission fluid. We’ll discuss its important role in the health of your engine, as well as the different types of fluids available. We’ll also go through some steps you can take to assess the transmission fluid in your vehicle.

What is transmission fluid, and why is it important?

The transmission has a big job. It’s what allows you to shift into different gears, like drive, park, and reverse. Changing gears is hard on the transmission. The role of the transmission fluid is to make this job run smoothly. It lubricates the metal components of the transmission, which decreases wear and damage. It also serves as a coolant to the transmission, making sure its temperature stays under control.

Types of transmission fluid

There are many different kinds of transmission fluid. Different makes and models require different formulas. Most transmission fluids can be categorized as either manual or automatic transmission fluids. Additionally, there are specialty fluids for specified transmissions.

Of these two varieties, manual transmission fluid is less common. It’s made for manual transmissions but is typically only needed for older vehicles. These days, manual transmission cars require automatic transmission fluid.

Automatic transmission fluid is much thinner than manual transmission fluid. That means the transmission can easily move in and out of gears, even when the temperatures drop. Automatic transmission fluid also plays a part in the following engine functions:

  1. Transmission coolant
  2. Gear lubrication
  3. Valve body operation
  4. Clutch operation
  5. Brake band friction
  6. Torque converter operation

Transmission fluids are either traditional, made of crude oil, or synthetic. The type of transmission fluid you need depends on the specifics of your vehicle. Synthetic fluid is formulated to withstand extreme heat from the engine. By contrast, traditional fluid can oxidize or break down at high temperatures. If you’re not sure what type of transmission fluid your vehicle requires, our transmission experts can help you figure it all out.

How to check your transmission fluid

Like other automotive fluids, transmission fluid requires periodic replacement at regular intervals. A visual inspection of your transmission fluid can help you figure out whether it’s time for a replacement. To do this, you need to find the transmission dipstick. This is usually found in the engine compartment underneath the hood. Some modern vehicles have transmissions that are completely sealed. If that’s the case for you, then refer to your owner’s manual or a licensed professional for more details on how to check the condition of your transmission.

If your vehicle does have a transmission dipstick, you can remove it to check the fluid’s level and condition. Remove the dipstick and wipe it clean. Next, slowly replace it and remove it once more. After taking it out a second time, you should see where your current fluid level lines up with the markings on the dipstick. This will help you see if your fluid level is low. Regular issues with low fluid usually point to a leak in your engine. If that’s the case, you’ll want to bring your car to a service provider to assess the situation.

Notice the Color

Once you’ve checked the fluid level, take a look at its color. A pinkish-red hue indicates a healthy transmission fluid. If it’s a darker shade that’s closer to a brownish-red, then your fluid needs to be replaced. You’ll know you have a problem on your hands if the transmission fluid is dark brown or black. This points to a serious issue with the transmission that needs repair. This is typically the result of skipping regular service intervals.

The transmission is one of the most expensive car parts to repair or replace. Routine replacement of the transmission fluid helps avoid major issues, saving you time and money.
