Fluid Services
Every fluid in your vehicle wears out eventually. Most people remember the oil and forget the rest, until a radiator hose bursts in July traffic or the brake pedal starts feeling soft.
The fluids we service:
- Coolant, which keeps the engine from overheating and protects against corrosion
- Brake fluid, which absorbs moisture over time and loses performance
- Power steering fluid, on vehicles with hydraulic steering
- Transmission fluid, covered in detail on our transmission service page
- Differential and transfer case fluid on trucks and four-wheel drive vehicles
- Windshield washer fluid, the easy one
Heat is hard on fluids
San Antonio summers push cooling systems hard. Old coolant loses its ability to protect the engine and can leave deposits that clog the radiator. If your temperature gauge climbs in traffic, or you see green, orange, or pink fluid under the car, get the cooling system checked before it leaves you on the shoulder of 410.
Trucks that tow need differential and transfer case service more often. So do vehicles that spend time off pavement or crossing water.
Part of our oil change service
Fluid services are part of our oil change service at 12040 O'Connor Rd. We check fluid levels during every oil change and tell you if something is low, dirty, or due. Brake fluid is also part of every brake repair inspection.
Questions we hear
How often should coolant be changed?
It varies by vehicle and coolant type. Many modern coolants last a long time, but check your owner's manual and have it tested if you are not sure.
Why does brake fluid need to be changed?
Brake fluid absorbs moisture from the air. Water lowers its boiling point and can corrode brake parts.
Can you check all my fluids during an oil change?
Yes. We check levels and condition during every oil change.
