Why Do Fluids Need To Be Checked Periodically?

2 minutesread


The gas in your car’s tank burns to make the engine run and needs to get replaced frequently otherwise you can’t drive anywhere. Much longer-lasting, but only slightly less important is the rest of the fluids in your car.

A well-cared-for engine ought to not need quite a quart or two of oil between oil changes unless there’s a leak somewhere. But because the valve stem seals/guides and piston rings to wear and age, more oil will get into the combustion chambers and be burned with the gasoline. Wear can even cause blow-by, with oil vapors being pushed into the breather system and filter by combustion gasses. Betting on the age of the vehicle and therefore the number of miles thereon, you need to be checking the oil level once every week, and positively once a month, even for late-model vehicles.


Cooling System:

Your car’s cooling system is sealed, and only vents to the atmosphere in the even of the car overheating. You must make it to some extent to test the extent of coolant in the overflow tank whenever you happen to be under the hood, just to be safe. If the cooling system develops a leak, you will not notice it until you lose enough fluid to make the car overheat, and overheating can cause serious engine damage. Your car can lose coolant in several ways in which aren’t as dramatic as steam pouring out of the hood.


Power Steering and Brake Fluid:

Power steering and brake fluid are important for the safe operation of your car. If a power steering hose were to leak you would possibly not notice until it becomes much hard to steer the car because of a loss of fluid. The brake fluid level will sink because the pads wear and therefore the fluid needs to push the pistons further out for effective braking. In extreme cases, or if there’s a leak somewhere, the fluid level can sink so low that the brakes become spongy because of air bubbles in the system.

You can never tell after you suddenly need to use your windshield washers – maybe there’s a sudden glare of sun across a grimy window or even you only got splashed with mud making it hard to determine. Better to stay the washer reservoir full so that in an emergency you’ve got the simplest way of cleaning your windshield no end.

Unlike the rest of the fluids mentioned, DEF does get used periodically without you even noticing it just by running your internal-combustion engine. Most vehicles will warn you once you are becoming low so you’ll be able to refill at your next fuel stop. If you’re on a protracted trip, through the kind of country where billboards advertise “last fuel for 100 miles” you ought to check the DEF level when filling up to avoid running go in the center of nowhere.
