Keeping your fluid levels topped off will ensure that your car’s engine is properly protected and that other important systems will work correctly. Fluid levels should be checked at least once a month.


Engine oil – Find the oil dipstick, a flat metal rod with a plastic handle on one end. Usually the oil dipstick will say the word OIL or have a picture of an oilcan on the handle. Pull the handle to remove the dipstick from the engine. Use a rag to clean off the oil on the dipstick and reinsert into the engine. Remove the dipstick once more and inspect the level of the oil. You will see lines that indicate that the oil level is full or that you should add oil. Add oil if necessary. Also, note the color and condition of the oil at this time. Oil should be brown, not black. If the oil is black, you are in need of an oil change.

Transmission fluid – In order to check the transmission fluid level on most vehicles, you should have the engine running with the transmission in neutral. Check with your owners manual for your particular vehicle. The transmission has a dipstick similar to the oil dipstick; it will usually be located behind the engine, closer to the firewall. Remove the stick, clean it, reinsert and remove to check the level. Again, there are lines that say if it is full or if you need to add fluid. Add transmission fluid if necessary.

Power steering fluid – The power steering pump is powered by the serpentine belt. Therefore, look for it near the belt. It has a reservoir with a cap that twists off. The cap will have a plastic stick with two lines on it, cold and hot. If the car has been sitting and is cool, the power steering fluid level should be at the cold mark. If the vehicle is at operating temperature, the level should be at the hot mark.

Brake fluid – The brake master cylinder is located near the firewall. Most newer master cylinders are clear or semi-translucent and have a mark on the side that designates that the fluid is full. Some older models may have a plastic dipstick attached to the cap, similar to the power steering reservoir.

Windshield washer fluid – Check your windshield washer fluid level to ensure that you can clean your windshield while driving if you need to.

Tire pressures – While not a 'fluid', you should check that your tire pressures are set to manufacture suggested levels once a month as well.
