Checking your vehicle fluids

Our vehicles need liquid to operate just as we do. Our four-wheeled friends use fluids to get us from point A to point B. With owning a car comes responsibility, so it’s vital to learn the essential fluids that help your vehicle operate. Without fluids, your car won’t drive, and it won’t be safe if it does. One of the simplest ways to maintain your car’s health is by regularly checking fluid levels at least once a month. You can gain a ton of useful information about your fluid levels with a visual inspection. As a reminder, always check your fluids while the car is turned off and cooled down. 

Below are fluids your vehicle uses to operate and why they are essential to monitor: 

Engine Oil 

 One of the most important oils to check is the engine oil. Metaphorically speaking, the engine oil is like the blood of your combustion engine. The oil’s purpose is to lubricate, clean, and seal various parts of the engine. It also prevents corrosion in the engine. The oil dipstick typically has a circular or yellow handle. To check your engine oil, remove the dipstick and wipe it clean with a rag. Place the dipstick back in and remove it. The goal is to make sure the oil levels are normal. If the oil looks dirty or reads low, it may be time for an oil change. 


Antifreeze serves a variety of functions for your vehicle. Antifreeze prevents the water in the radiator and engine from freezing during cold temperatures and boiling in hot temperatures. It also serves to lubricate any moving parts it touches. The coolant tank is translucent and has markings on it to indicate the fluid levels.

Brake fluid

Brake fluid is in either a metal or a transparent reservoir. Most vehicles have transparent tanks that allow you to check fluid levels by checking the maximum and minimum markings from the outside. If you have a metal reservoir, you’ll need to remove the cap to check the brake fluid levels. Experts suggest that most vehicles have their brake fluid changed every 45k miles, and if it’s low, feel free to top it off. If it seems unusually low, there may be a leak, and you should consult an automotive specialist. 

Automatic Transmission Fluid

Vehicles that are newer and updated models may not have a transmission dipstick, and you may need to check with an automotive specialist who can assist with checking. You can leave your car idling in the park gear to check the transmission fluid levels for older vehicles. The transmission fluid’s red coloring is how it distinguishes itself from oil. You will use a similar process as checking your engine oil – remove the dipstick, wipe it, insert it, remove it, and check the levels. If the transmission fluid is low, it’s best to add more or consult an expert. 

Make sure your car isn’t dehydrated by staying on top of its essential fluids. Whether you’re doing a quick commute or planning a long road trip, it’s critical to give your car a little extra love and attention. You’re always welcome to bring your vehicle in, and we’ll be happy to offer service for your fluids.
