Car Care - About Fluids

Engine oil

Oil keeps your engine lubricated and reduces heat. Your oil filter helps prevent engine damage by removing contaminants that build up in the oil. Carbon, dirt, and debris become suspended in the oil and cause it to lose effectiveness, leading to increased engine wear and decreased fuel economy. Regular oil and filter changes keep your engine clean and lubricated.

Transmission fluid

Your transmission transfers energy from the engine to the wheels to get your vehicle moving. Transmission fluid lubricates, cools, and cleans the inside of the transmission while maintaining the necessary pressure inside the transmission required for it to function properly. Whether your transmission is automatic or manual, the transmission fluid eventually breaks down. If it isn’t replaced, components inside can overheat, causing transmission failure.

Engine (Radiator) coolant

Radiator coolant, or anti-freeze as it’s commonly known, ensures your engine doesn’t freeze or overheat. Coolant works by removing heat from the engine block. It protects the engine and lubricates the water pump seals. Over time, coolant loses its ability to protect vital engine parts. 

Differential fluid

The differential works with the transmission to deliver power from the engine to the axle to turn the wheels. Like engine oil, heat causes wear on differential fluid, which can lead to excessive wear on the gears and bearings. To prevent this, make sure your differential fluid is changed regularly.

Transfer case fluid (4-wheel & all-wheel only)

The transfer case is the heart of a vehicle’s four-wheel or all-wheel drive system. It provides power to both the front and rear differential assemblies, which turn your wheels. It also allows you to switch between gears, such as 4High and 4Low. Like engine oil, the fluid that lubricates the transfer case will begin to break down over time and lead to excessive wear on bearings and gears.
