Fluid Dynamics: Quenching Your Car's Thirst for Health and Performance
July 25, 2024
Have you ever wondered what keeps your car running smoothly?
It's not just the engine and tires—there's a whole system of fluids working behind the scenes to keep everything in top shape.
At David's Automotive Repair, we're here to explain why these fluids are so crucial and how they can affect your car's performance.
Engine Oil:
Engine oil is like the lifeblood of your engine, keeping all its moving parts lubricated and protected. There are different types of engine oil:
-
Conventional Oil:
This is the traditional oil refined from crude oil. It's suitable for many older engines and offers basic protection.
-
Synthetic Blend
: A mix of conventional and synthetic oils, offering some benefits of synthetic oil at a lower cost.
-
Full Synthetic
: Engineered for modern engines, providing superior lubrication, performance in extreme temperatures, and longer intervals between changes.
Choosing the right oil depends on your car's age, driving conditions, and manufacturer recommendations. Using the wrong type or mixing different oils can reduce efficiency and potentially damage your engine over time.
Coolant:
Coolant circulates through your engine to regulate temperature and prevent freezing or overheating. Mixing different types of coolant can cause chemical reactions that lead to corrosion and cooling system damage. It's important to use the coolant specified by your vehicle manufacturer and to flush and replace it at recommended intervals.
Transmission Fluid:
Transmission fluid lubricates and cools the gears in your transmission system. Mixing different types of transmission fluid, like ATF and MTF, can compromise performance and lead to transmission problems. Each type of transmission fluid is formulated for specific transmission designs and operating conditions, so it's essential to use the correct fluid and change it according to your car's maintenance schedule.
Brake Fluid:
Brake fluid transmits force from the brake pedal to the brake components. Mixing different types of brake fluid can lead to reduced braking performance and corrosion within the brake system. Always use the type of brake fluid recommended by your vehicle manufacturer and replace it as recommended to maintain safe braking.
Power Steering Fluid:
Power steering fluid assists in turning the steering wheel smoothly. Mixing different types of power steering fluid can cause damage to the power steering system components, affecting steering performance and reliability. Stick to the fluid specified in your owner's manual and keep it at the proper level for optimal steering control.
Gear Oil:
Gear oil is used in manual transmissions, transfer cases, and differentials to lubricate and protect the gears from wear and overheating. Using the wrong type of gear oil or mixing different viscosities can lead to gear and bearing wear, reduced performance, and potential mechanical failures. It's crucial to use the gear oil recommended by your vehicle manufacturer and replace it according to the maintenance schedule.
Each of these fluids is essential for your car's performance and longevity. Regular maintenance, including fluid checks and changes, ensures your vehicle operates efficiently and safely. At David's Automotive Repair, we're dedicated to helping you understand and maintain your car's fluid systems.

When you bring your vehicle in for A/C testing and analysis, we recharge the system with fresh refrigerant and add a special dye that glows under a blacklight . This helps us track down the leak, even if it’s small or hidden deep inside the system. Some newer vehicles already have this dye from the factory, but not all do. Either way, we’ll use the right tools to spot where the refrigerant is escaping—so we can fix the problem and get your A/C blowing cold again. Don’t wait for it to get worse. If your air isn’t cold, let us take a look before summer really heats up. Call 972-625-1836 to schedule a reservation for A/C testing and repair.
If your windshield wipers are worn out , streaking , or squeaking , they might not do their job—and that can be dangerous. Windshield wipers are extremely important for your teen during the 100 Deadliest Days of Summer. Good wipers help you see the road clearly during heavy rain, but they also come in handy for clearing dust, bugs, and even pollen. In Texas, summer heat can dry out the rubber on your wiper blades fast, causing them to crack or tear. If you notice your wipers skipping across the glass or leaving behind streaks, it’s time for a new set. Washer fluid is important too. Running out can leave your windshield dirty and tough to see through, especially during long drives or road trips. Before your next summer outing, take a quick look at your wipers and test your washer spray. If you’re unsure, we’re happy to check them for you. Call us at 972-625-1836 to schedule a reservation—we’ll make sure your view of the road is clear and safe.
One of the most common causes is a faulty blend door motor. This small part helps control the temperature inside your vehicle by opening and closing doors in your air system. When it starts to fail, it can get stuck or try to move the door the wrong way—which is what causes the clicking sound. You might still feel air coming from the vents, but it may not be the right temperature. Sometimes, it’s stuck on hot when you want cold, or vice versa. Over time, the noise can get worse and the motor may stop working altogether. If your dash is clicking, it’s a good idea to have it looked at before it turns into a bigger repair. Give us a call at 972-625-1836 to schedule a reservation. We’ll take care of the noise—and make sure your A/C is working like it should.

Storms can roll in quickly, and cloudy mornings or dusty evening drives can make it harder to see the road. That’s why working headlights aren’t just for nighttime, they help you see clearly and help other drivers see you. If your headlights look cloudy or yellow, they may not shine as bright as they should. And if one is dim or burned out, it can throw off your depth perception, making driving more dangerous. You may also be at risk of getting pulled over or missing important signs. Before you or your teen hits the road this summer, take a few minutes to check your lights. Turn them on, walk around your car, and make sure both front and rear lights are working. A quick fix today can help prevent an accident tomorrow. Need help with headlight replacement or cleaning? Give us a call at 972-625-1836 to schedule a reservation.
Your car’s cooling system helps keep the engine from getting too hot. When temperatures hit the triple digits, your cooling system has to work extra hard. If something isn’t working right, your engine could overheat and leave you stuck on the side of the road. Signs of cooling system problems include your engine running hotter than normal, seeing leaks under your car, stange smells, and steam. Even if you don’t notice anything wrong, it’s a good idea to have your cooling system checked before summer gets too hot. At David’s Automotive Repair, we check your radiator, hoses , coolant levels , and water pump to make sure everything is working like it should.

Hot pavement, long drives, and high temperatures can make your tire pressure go up and down. If your tires have too much or too little air, you are more likely to have a blowout , lose control of your car, or wear out your tires faster .

Keeping your tires properly filled and checked can make a big difference in how safe your drive is. At David’s Automotive Repair, we check your tire pressure, inspect your tires for wear, and help you stay ready for all your summer adventures. A few minutes spent today can help you avoid bigger problems tomorrow. Drive safe this summer—call 972-625-1836 to schedule your tire inspection reservation with us!
Every tire on your car wears differently. Depending on its position, road conditions, and your driving habits. Without regular rotation, you’ll experience uneven wear. This can lead to poor handling , lower fuel efficiency , and a shorter tire lifespan . Generally, tires should be rotated every other oil change. But heavy driving, towing, or rough roads may require more frequent checks. Regular rotations also help your suspension stay balanced and can prevent bigger issues down the road. At David’s Automotive Repair, we’ll make sure your tires are rotated properly and check for any signs of trouble. Our team is committed to helping drivers in The Colony and nearby communities stay safer on the road. Keep your car riding smoothly—call 972-625-1836 to make your reservation today!
