While engine oil gets all the attention, your vehicle relies on a host of other critical fluids to operate safely and efficiently. Neglecting them can lead to system failures and expensive repairs.
Coolant (Antifreeze): This fluid prevents your engine from overheating in the summer and freezing in the winter. It circulates through the engine and radiator to regulate temperature. Low or old coolant can lead to overheating, a warped cylinder head, or a damaged radiator. It should be flushed and replaced according to your owner’s manual, typically every few years.
Brake Fluid: This is a hydraulic fluid that transfers the force from your foot on the brake pedal to the brakes on the wheels. Over time, brake fluid can absorb moisture from the air, which lowers its boiling point and can lead to brake failure under heavy use. It should be checked regularly and changed every two to three years.
Transmission Fluid: This fluid lubricates and cools the complex internal components of your transmission. On most cars, you can check its level with a dipstick. Low or burnt-smelling transmission fluid is a sign of a problem that needs immediate professional diagnosis to avoid transmission failure.
Even Windshield Washer Fluid plays a vital safety role, ensuring you can clear your view in an instant. Regularly checking these fluids is just as important as your routine oil change.
