At Ed Hicks INFINITI in Corpus Christi, we’re here to help you stay ahead of routine maintenance with expert service tailored to your vehicle’s exact needs.
Every fluid in your vehicle plays a crucial role in performance, safety, and longevity. Some regulate temperature. Others help power your brakes, manage gear shifts, or reduce friction inside the engine.
When those fluids are low, contaminated, or past their service life, your vehicle can lose efficiency—and in some cases, suffer damage that’s costly to repair. Staying current with fluid checks and replacements is one of the most important ways to maintain your INFINITI’s smooth, responsive feel.
Let’s take a closer look at the key fluids in a car, what they do, and how often they should be checked or replaced.
Engine oil is your vehicle’s first line of defense against heat and friction. It keeps internal components lubricated and running efficiently. When it breaks down or becomes dirty, the engine has to work harder—often leading to overheating and wear.
Most INFINITI models require synthetic oil changes every 5,000 to 7,500 miles, though your vehicle’s specific maintenance schedule will offer the best guidance. You can check the oil level yourself using the dipstick under the hood—just be sure the engine is cool and turned off first.
Transmission fluid helps maintain smooth, quiet gear changes while also keeping internal parts cooled and lubricated. Low or worn fluid can result in harsh shifting, slipping gears, or strange noises—none of which belong in a luxury vehicle.
Some INFINITI transmissions are sealed, meaning fluid checks and service should be performed by a professional. Typically, this fluid should be inspected around 30,000 to 60,000 miles, depending on your driving habits.
Brake fluid is responsible for transmitting pressure from the brake pedal to the brake components at each wheel. Over time, it absorbs moisture, which reduces its effectiveness and can corrode parts of the brake system.
If your braking feels soft or spongy, or if your brake warning light is on, it may be time to inspect the fluid. It’s recommended that you change brake fluid every two to three years. A quick visual check of the reservoir can reveal if it’s dark, low, or in need of replacement.
Coolant is essential for managing your engine’s temperature in both hot and cold weather. It prevents overheating, freezing, and corrosion throughout your cooling system. When coolant breaks down or leaks, it can lead to engine overheating and costly damage.
INFINITI recommends checking coolant levels regularly and replacing it as needed—usually every 60,000 miles or every few years, depending on your model and driving conditions. Always check coolant when the engine is cool, and never remove the cap while it’s hot.
If your INFINITI is equipped with hydraulic power steering (some models use electric systems), this fluid makes steering smooth, easy, and responsive. When fluid levels are low or contaminated, you might notice difficulty turning or hear whining sounds while steering.
It’s smart to have power steering fluid checked during regular maintenance visits. If your vehicle uses an electric steering system, no fluid service is needed.
Washer fluid may not affect performance, but it certainly affects visibility. A clean windshield is key to safe driving—especially in rainy or dusty conditions. Topping off this fluid regularly is a simple way to stay ready for the road ahead.
Look for the washer reservoir under the hood, typically marked with a windshield icon. Top it off as needed with a quality washer fluid—especially before road trips or seasonal weather shifts.
