The 8 Best Essential Fluids Your Vehicle Needs To Function

Unless you’re a car mechanic, you might not know that your car requires some essential fluids to run properly. This blog post by The Key Online – Lawton will explain what each of those fluids are and why they’re crucial for your car.

Engine Oil

The most vital fluid in your car is engine oil, which keeps things moving smoothly within the engine. It also protects the moving components of your engine from heat damage, and its cleaning capabilities may assist in removing debris from the engine ports. Engine oil comes in different grades, and you should always use the grade recommended by your car’s manufacturer.


Another vital fluid is coolant, which helps to keep your engine from overheating by regulating its temperature. Coolant also circulates through the radiator, where it dissipates heat and keeps the engine running at a consistent temperature.

Brake Fluid

This fluid helps to stop your car by transferring pressure from the brake pedal to the brake pads. When your car’s brake fluid level is low, you may experience decreased braking power. You should replace your brake fluid every couple of years or whenever it becomes contaminated.

Transmission Fluid

This fluid helps transfer power from the engine to the transmission. It’s important to keep your transmission fluid clean and at the correct level, as it protects the gears in your transmission. If it’s low or dirty, your car may not move as smoothly as it should.

Power Steering Fluid

This fluid helps you steer your car. It’s essential to keep your power steering fluid at the correct level, as it keeps your vehicle from feeling “heavy” when you turn the wheel. If it’s low or dirty, your car may not respond as well when you need to make a quick turn.

Windshield Washer Fluid

This fluid helps keep your windshield clean while you’re driving. It’s critical to keep your windshield washer fluid at the correct level, as it enables you to see clearly while you’re driving. If it’s low or dirty, your windshield may not be as clean as it should be.


This helps protect your engine from damage caused by cold weather. It’s essential to keep your antifreeze at the correct level, or else your engine may freeze.

Radiator Fluid

Radiator fluid helps keep your engine from overheating. If there’s not enough radiator fluid, your car may overheat and be seriously damaged. Radiator fluid is essential for keeping your vehicle running properly, so it’s crucial to make sure you have the correct level at all times.
