What Fluids Should I Be Checking Regularly?
Your car relies on a handful of essential fluids to keep everything moving properly. Start with engine oil, the lifeblood of your vehicle. Pull out the dipstick, wipe it clean, reinsert it, and check the level and color—dark or gritty oil means it’s time for a change.
Next, check the coolant in the overflow tank. This helps prevent overheating during hot days in Rio Grande traffic. Your transmission fluid is another big one—it should be bright red or pink, not brown. Then there’s brake fluid, which keeps your braking system responsive. If it’s looking murky, it’s time to top up or replace. Don’t forget the windshield washer fluid — because clear visibility is just as important as anything under the hood!

How Often Should I Check My Car Fluids?
A quick inspection once a month is a good rule of thumb. However, if you’re planning a road trip or driving long distances, check them before hitting the highway. Seasonal changes can also affect fluid levels—hot summers or humid weather can cause faster evaporation.
Keeping up with car fluids doesn’t require a mechanic’s degree—just a few minutes and a little know-how. If you’re ever unsure, the service team at Flagship Mazda in Rio Grande, PR, is always happy to help. A little maintenance today means a lot more confidence behind the wheel tomorrow!
