A car requires a number of different fluids to keep running its best and to protect the engine and other internal parts. During routine oil changes, fluids are typically checked to ensure proper levels, and they are changed or topped off as necessary. To better understand these fluids and the important role they play in keeping your vehicle safe, four of the most common ones are discussed below.

What Are the Main Types of Car Fluids?

1. Oil

Motor oil lubricates the engine, reduces friction, and prevents the vehicle from overheating. It also safeguards the engine from rust and corrosion and traps dirt and contaminants, which it then deposits in the oil filter. Most vehicle manufacturers recommend oil changes every 7,500 to 10,000 miles, though some may suggest oil changes as often as every 5,000 miles; check your owner's manual for your car's exact requirements.

2. Transmission Fluid

Transmission fluid lubricates and cools the transmission system while facilitating the smooth operation of the gear shifts. Manufacturers want you to schedule a transmission fluid change every 30,000 to 60,000 miles. If you often tow a trailer, haul heavy loads, or drive routinely in stop-and-go traffic, more frequent transmission fluid changes may be necessary.

3. Radiator Fluid

Radiator fluid, also called antifreeze or coolant, absorbs heat from the engine and keeps the car from overheating. When an engine runs, the radiator fluid constantly moves through it and back to the radiator, which is attached to the front inner portion of the vehicle. This location allows air to pass through the radiator fins, where it cools the moving coolant. Radiator fluid should be changed every 30,000 miles or so.

4. Power Steering Fluid

Power steering fluid helps transfer power to your car's steering system. It allows you to control the vehicle and turn the wheels with ease. Consult your owner's manual for the manufacturer's recommended schedule regarding power steering fluid changes. If you notice the steering wheel tugging back when you turn, it's likely an indicator that a steering fluid change is in order.
