Checking your car’s fluids is an important part of auto maintenance. However, many new drivers may not be sure exactly what fluids are necessary and how to check them or tell if something’s wrong. You can have the levels checked during a professional inspection or tuneup, but here’s a guide to what they do and the signs that service is needed. 

5 Oils and Fluids Your Car Needs

1. Transmission Fluid

Transmission fluid is a lubricant that helps to keep your car's transmission running smoothly. It is essential to keep your transmission cool and prevent it from overheating. If your transmission overheats, it can cause significant damage to your car's engine. 

This fluid should last about 100,000 miles or more, but have it checked if you notice difficulty shifting or slipping out of gear. Additionally, brown or red fluid under the vehicle may indicate a leak from this system.

2. Coolant

Coolant, also known as antifreeze, is responsible for regulating your car's engine temperature. It helps to prevent your engine from overheating and freezing in extreme temperatures. If you don't have enough coolant in your car, your engine could overheat, causing significant damage. Conversely, if your car has too much coolant, it can cause your engine to freeze. 

Check the level every six months—particularly in the summer when the temperature gauge on the dashboard tends to read hot. Additionally, a leak of red or green liquid under the vehicle often indicates damage to the coolant tank or lines, so have this checked immediately.

3. Engine Oil

Engine oil lubricates your car's engine and prevents it from overheating. If you don't have enough engine oil in your car, it can cause significant damage to your engine. 

Conversely, if you have too much engine oil in your car, it can cause your engine to overheat. Most cars need an oil change between every 5,000 to 10,000 miles; check your owner’s manual for specifics, and always take the car in when the check-engine light comes on. 

4. Brake Fluid

Brake fluid is responsible for transmitting force from your brake pedal to your brakes. If you don't have enough brake fluid in your car, your brakes won't work correctly, putting you and your passengers in danger. Have the fluid completely flushed and replaced every two years or 20,000 miles to ensure the brakes work properly. 

5. Power Steering Fluid

Power steering fluid helps transmit force from your steering wheel to your tires. Without power steering fluid, your steering wheel can be difficult to turn, especially at low speeds. Check the level every three months or if you notice your steering wheel is harder to turn than usual.
