Here is a rundown of some essential automotive fluids, what they do, and how to check them:

Engine oil:

The engine oil is responsible for lubricating the moving parts in your engine and preventing them from grinding together, causing heat, and eventual damage. To check your engine oil, locate the dipstick, remove it, and wipe it clean. Then reinsert it and remove it again to read the oil level. If it’s low, top it up with the correct oil

Transmission fluid:

The transmission fluid acts as a lubricant to the transmission gears and ensures they are functioning correctly. To check the fluid, find the dipstick, remove it, and wipe it clean. Reinsert the dipstick and check the reading. The fluid should be a clear red color. If it's a brownish or burnt smell, it's time for a replacement.

Brake fluid:

The brake fluid ensures the brakes work smoothly and prevents rusting and corrosion within the braking system. To check your brake fluid level, locate the brake fluid reservoir, and ensure it’s at the proper level indicated on the reservoir. If it's low, add the proper brake fluid and inspect for leaks.

Coolant:

The coolant helps regulate your engine temperature by absorbing the heat generated from the combustion of fuel. Check your coolant levels when the engine is cool, locate the reservoir tank and verify that the fluid is between the minimum and maximum levels.
