Essential Fluid Replacement: Which Fluids you should monitor regularly

The fluids that your vehicle needs to operate can be categorized into three groups: engine oil, coolant, and brake fluid. These fluids are vital to ensure the functionality of your vehicle and should be monitored regularly. If they're not checked often enough, you may end up with a vehicle that won't start or need expensive repairs. In this article, we'll go over what liquids you should check for in your car's engine, radiator, and brakes, how often you should change them, and what warning signs there maybe if something is wrong.

Engine Oil

One of the most important fluids in your vehicle is engine oil. Engine oil helps to lubricate the moving parts of your engine, preventing them from rubbing against each other and wearing down. Over time, the oil can become contaminated with dirt, metal shavings and other debris, which can cause damage to your engine if it's not replaced.

How to Check Your Engine Oil Level

The best way to check your engine oil level is to use the dipstick usually located near the engine. The dipstick is a long, metal rod with a rubber or cloth tip at one end. To check your engine oil level, remove the dipstick and wipe it clean with a cloth or paper towel. Then, insert it fully into the engine and pull it out. If you can't see an oil mark on the tip of the stick, your oil is low and needs to be changed. If you see a high-level mark on the stick, add the type of oil the owner's manual recommends until it reaches the add level mark on the stick.


The coolant in your vehicle helps to keep the engine from overheating by transferring heat away from the engine and dissipating it into the air. Coolant also contains corrosion inhibitors that help protect the engine's metal parts from rusting and corroding.

How to Check Your Coolant Level

The best way to check your coolant level is to use the radiator cap. The radiator cap is a metal lid that's threaded onto the top of the radiator. To check your coolant level, remove the radiator cap and look at the coolant fill line. If the coolant is below the fill line, add more coolant until it reaches it.

Brake Fluid

Your vehicle's braking system requires brake fluid to transfer pressure from the brake pedal to the hydraulic valves that control the brakes. Brake fluid can become contaminated by water or other substances, causing it to lose its effectiveness and possibly leading to difficulties stopping your vehicle. You should check your brake fluid regularly and change it if necessary.

How to Check Your Brake Fluid Level

The best way to check your brake fluid level is to use the fluid reservoir. The brake fluid reservoir is a translucent plastic container located near the brake pedal. To check your fluid level, remove the reservoir cap and look at the fluid level on the inside of the container's neck. If the fluid is below the fill line, add more brake fluid until it reaches it.

The brake fluid needs replacement if there is a sign of corrosion or rust inside the brake fluid reservoir. If you need Essential Fluid Replacement, our automotive repair shop provides automotive service and automotive repairs to all.
