Wondering what fluids need to be changed in a car? Learn how to check fluids in your car and where to get car fluids checked near Robstown, TX.
Let’s be real—car maintenance isn’t the most exciting part of your week. But it’s one of the most important if you want your vehicle to stay reliable, safe, and road-trip ready. Checking the fluids in your car is one of the simplest ways to keep everything running like it should.
So, what fluids does a car need? And more importantly, what fluids need to be changed over time? From engine oil to brake fluid, these essential fluids are the unsung heroes of your daily drive. Knowing how to check them and where to get car fluids checked in Robstown, TX can help you avoid surprise repairs and keep your ride performing at its best.
Each fluid in your car plays a specific role. Some help cool the engine, others keep your brakes working properly or your steering smooth. When any of these fluids get low or dirty, the systems they support start to struggle. Over time, that can lead to wear, damage, or even breakdowns.
The good news? Catching fluid issues early is easy—and it makes a huge difference. Regular fluid checks protect your engine, improve safety, and even help your car hold its value longer. If you’re not sure where to start, the service team at Hicks Family Nissan is here to help with fast, friendly service right here in Robstown.
If you’re wondering which fluids in a car deserve your attention, here’s a breakdown of the big six—what they do, why they matter, and how to check them. Always make sure your vehicle is off, cool, and parked on a flat surface before checking.
Engine oil keeps your engine parts lubricated and helps prevent overheating. Without it, friction builds up fast—and so does the damage. Most vehicles need an oil change every 5,000 to 10,000 miles, though your owner’s manual will have the most accurate timing for your model.
To check the level, find the dipstick under the hood (usually has a yellow or orange handle). Pull it out, wipe it clean, dip it back in, then pull it out again to see the oil level and color. If it’s low or dirty, come see us!
Transmission fluid helps your car shift gears smoothly and keeps the transmission cool. When it’s low or old, you may notice delayed shifting, strange noises, or jerky gear changes. Most cars need this fluid changed every 30,000 to 60,000 miles. Some vehicles let you check the level with a dipstick, but many need a professional inspection. If you’re not sure, stop by and we’ll take care of it.
Brake fluid makes it possible for you to stop quickly and safely. If the fluid gets too low or starts to absorb moisture, your brakes can feel soft or less responsive. It’s a good idea to replace brake fluid every two to three years or whenever your brake pads or rotors are serviced. You can check the reservoir under the hood—just make sure the level is between the minimum and maximum lines.
Coolant helps regulate your engine’s temperature and prevents it from overheating or freezing in extreme conditions. When coolant gets low or dirty, the engine can overheat, which may lead to serious repairs. Some types of coolant last up to 10 years, but check your manual for the right interval. To check it, look at the reservoir when the engine is cool—the fluid should be between the marked lines.
This fluid helps you steer with ease. If it’s low, you might notice stiff or jerky steering. Depending on your vehicle, this fluid may only need to be topped off occasionally, but checking it every few months is a smart move. The reservoir is usually labeled under the hood, and the fluid should fall within the range on the side of the tank.
Washer fluid doesn’t affect how your car runs, but it definitely impacts your visibility. If the reservoir runs dry, you won’t be able to clear dirt, bugs, or grime from your windshield. You can check it by looking for the clear tank with the windshield icon. Just pop the cap and refill it if it’s low.
There are a few other fluids in a car—like differential fluid and transfer case fluid—that usually don’t need regular attention. These are often inspected during major service intervals. If you’re hearing strange noises or your vehicle feels different, it’s worth getting them checked out during your next visit.
