Transmission Fluid Exchange

Exchanging used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. With automatic transmissions, fluid quality is vitally important due to the complex nature of transmissions. Please do not wait until the vehicle shifts poorly; it may be too late for a flush, and flushing an already worn-out transmission can actually make it worse. Bring your vehicle by Finsanto Automotive on time for your transmission services in San Antonio, TX, so your transmission will last!

Radiator Fluid and Coolant/Antifreeze Exchange

Radiator fluid, or Coolant/Antifreeze, works hard to keep your engine cool. Like any fluid in your engine, coolant has a limited lifespan and should be exchanged at proper intervals to keep the fluid fresh and your engine clean! It would be best to change your radiator fluid every 2 to 3 years (24,000-36,000 miles) for proper maintenance. We’ll push the old fluid out under pressure, run a cleaner through the whole cooling system, and pump in new fluid, so your cooling system is fresh and efficient again!

Brake Fluid Exchange

Brake fluid transmits pressure from your brake pedal to the brakes on your car. It’s important that this hydraulic fluid stays clean and free of contaminants to work properly. Over time, contaminants and water can accumulate in the fluid. This affects braking efficiency and can corrode the lines that carry the fluid to your brakes. Left unchecked, it can lead to a soft brake pedal and even cause total brake failure! Change your brake fluid every two years or 30,000 miles to avoid any braking system failure.

Differential Fluid Exchange

Differentials are vital to transmitting power from your engine to your wheels and are lubricated by a thick oil. Over time, this fluid breaks down and needs to be replaced, or it will lead to poor performance, noise, and in the worst cases, total failure and breakdown. If the differential breaks down, a total replacement is required to get you on the road again. You should have your differential fluid every 40-60,000 miles.

Power Steering Fluid Exchange

This fluid lubricates all the moving parts in the power steering system and prevents wear and tear by removing contaminants. Proper fluid also conditions the o-rings and seals, but contaminated fluid can damage these seals. It’s important to regularly exchange the power steering fluid to extend the life of your steering components, such as the pump, power steering rack, and pinion assembly.
