What Fluids Does My Car Have?

Brake Fluid
Brake Fluid
Every time you tap the brake pedal, brake fluid is pumped to the calipers of each wheel to make the pads and rotors press together to stop your vehicle. Moisture builds up in the brake fluid over time and can result in algae and/or rust. Flushing the brake system makes your parts last longer and can cause a firmer pedal for more immediate response in braking. To determine if your brake fluid is due - we check the color, moisture content, and records of last mileage/time serviced.
Transmission Fluid
Over time and mileage, the transmission fluid heats cycles causing the fluid to become oxidated and change from a red hue to a dark brown/black. Transmission fluid is also a detergent and keeps your transmission gears clean. By not changing the fluid, it can lose lubrication and slowly wear down the internal parts of the transmission. For automatic transmissions, a harsher shift can be felt from dirty fluid.
​
*Automatic transmissions should have the fluid changed every 30,000 miles. CVT transmission fluid lasts longer about 35,000-40,000 miles and manual transmission fluid is recommended every 50,000 miles.
Coolant
​Coolant is a 50/50 mixture of water and antifreeze. Coolant has additives including lubrication for the water pump and anti-corrosion properties to prevent rust from forming in the cylinder block and radiator. Over time, the additives break down and the coolant becomes more acidic resulting in a loss of these properties. This can cause the coolant to not work as efficiently.
​
*Recommended every 60,000 miles/5 years.
Front & Rear Differential and Transfer Case
The oil in the transfer case and differentials acts as a cooling agent to the clutches and gears to prevent overheating and friction of metal on metal. If you tow and/or over-load the vehicle, these fluids should be changed more frequently.
​
*FWD vehicles do not have these components. On some vehicles, these fluids are not serviceable. These three fluids are due every 40,000 miles.
