For many car owners, knowing when these fluids need attention and how to approach servicing can be challenging without the right diagnostic tools.
As a Honda car owner, I rely on the ANCEL V6 Pro OBD2 scanner, a bidirectional scan tool that helps me handle these complex tasks on my own.
Brakes
I noticed that my car felt different when I pressed the brake pedal. The pedal seemed a bit soft, and there was a slight vibration when I braked.
Since these could be signs of a problem in the braking system, I decided to investigate further using the ANCEL V6 Pro.
After connecting the scanner, I accessed the ABS (Anti-lock Braking System) to review real-time brake data.
The V6 Pro showed readings of brake line pressure across each wheel.
This pressure data indicated some slight inconsistencies, with one side showing lower pressure than expected.
Lower brake line pressure like this can suggest there might be air bubbles or moisture in the brake fluid or that the fluid might not be performing as effectively as it should.
Moisture and air in brake fluid lower its boiling point, which can cause soft or unsteady braking, especially under harder braking.
After seeing this imbalance in pressure, I checked the brake fluid visually and confirmed it had a darker color, indicating it was time for a change.
I replaced the old fluid with fresh brake fluid, which is less likely to absorb moisture.
After flushing the lines, I ran another check with the V6 Pro to confirm that the brake line pressures were now balanced, and the braking felt firm and responsive again.

Coolant
I accessed the live data stream to view the engine temperature in real time.
The V6 Pro confirmed that the temperature was slightly above the normal operating range, especially during idle periods.
This scan tool allowed me to go beyond basic temperature readings by activating specific tests in the cooling system.
Using its bidirectional control, I was able to initiate a fan test to see if the cooling fan was operating as it should.
The fan started up and responded normally, which ruled out a mechanical issue with the fan motor. This left the coolant itself as the most likely cause.
I also checked for any signs of coolant leaks around the hoses and radiator to be thorough.
With this data and my observations, I decided to flush out the old coolant and replace it with fresh fluid, as worn-out coolant can lose its cooling efficiency over time.
After the replacement, I used the V6 Pro again to check the engine temperature during a test drive. The engine temperature remained stable and well within the normal range.

Transmission
To investigate what is going on my transmission, I turned to the ANCEL V6 Pro and accessed the transmission diagnostics.
Once connected, the V6 Pro provided real-time data on transmission temperature and pressure.
Transmission fluid might not be performing optimally, as degraded fluid often results in less effective cooling and lubrication within the transmission system. Transmission fluid that is too worn can cause sluggish gear shifts and reduced response.
The scanner’s detailed diagnostics helped me confirm that the fluid change had restored the transmission’s performance.
Why ANCEL V6 Pro
The ANCEL V6 Pro is more than a basic scanner—it’s a bidirectional tool that lets me interact with my car’s systems directly.
Unlike regular scanners, it allows me to test components like the cooling fan and ABS to see real-time responses.
Though bidirectional tools are pricier, the V6 Pro has saved me time and money by enabling me to handle diagnostics myself.
FAQs
How often should I replace my car’s coolant?
Coolant generally needs to be replaced every 30,000 to 50,000 miles, depending on your vehicle’s make, model, and the type of coolant used. It’s a good idea to check the owner’s manual or consult a mechanic for the recommended interval for your specific car.
How often should brake fluid be replaced?
Brake fluid typically needs to be changed every 2-3 years, or roughly every 30,000 miles. It’s a good idea to check it annually, as old brake fluid can absorb moisture, which lowers its effectiveness.
What happens if I don’t change my brake fluid?
Old brake fluid can lead to reduced braking power and may cause the brake pedal to feel soft. Over time, it can also corrode brake components, leading to more serious and expensive repairs.
