Hydraulic Power Steering: Traditional Strength

For many years, hydraulic power steering (HPS) has been the standard in vehicles. This system operates using a pump driven by the engine, which pressurizes hydraulic fluid (usually power steering fluid). The pressurized fluid is then used to assist in turning the steering wheel, reducing the effort required by the driver.

Key Features of Hydraulic Power Steering:

- Proven Reliability: Hydraulic systems are known for their durability and reliability. They have been used extensively in various vehicle models with consistent performance.

- Responsive Feel: Hydraulic power steering provides direct feedback to the driver, enhancing the feel of the road and the vehicle's handling characteristics.

- Maintenance Needs: Regular maintenance, such as fluid checks and occasional flushing, is necessary to ensure optimal performance and longevity of hydraulic power steering systems.

Electronic Power Steering: Efficiency and Innovation

In recent years, electronic power steering (EPS) has gained popularity due to advancements in automotive technology. Instead of hydraulic fluid and pumps, EPS systems use an electric motor to assist with steering. This motor is controlled by sensors that detect the driver's steering input and vehicle speed, adjusting the steering assistance accordingly.

Key Features of Electronic Power Steering:

- Efficiency: EPS systems are more energy-efficient compared to hydraulic systems because they only use power when steering assistance is needed. This can contribute to improved fuel efficiency.

- Adaptive Control: Electronic systems can adjust steering feel and assistance levels based on driving conditions, enhancing both comfort and safety.

- Maintenance Benefits: EPS systems generally require less maintenance compared to hydraulic systems, as there are no fluids to check or replace regularly.

Differences and Similarities:

- Functionality: Both hydraulic and electronic power steering systems serve the same primary purpose of assisting the driver in steering the vehicle. However, they achieve this through different mechanisms (hydraulic pressure vs. electric motor).

- Feedback: Hydraulic systems typically provide more direct feedback to the driver through the steering wheel compared to electronic systems, which may feel more artificial to some drivers.

- Complexity: Electronic power steering systems are generally more complex in terms of electronics and control systems compared to hydraulic systems, which can affect repair and diagnostic procedures.

Choosing a car with the Right System:

When it comes to choosing between hydraulic and electronic power steering systems, vehicle manufacturers consider factors such as performance, cost, fuel efficiency, and overall driving experience. At David's Automotive Repair, our certified technicians are trained to diagnose, repair, and maintain both types of power steering systems with precision and expertise.

To check it, make sure your car is parked on a flat surface with the parking brake engaged. For most cars, the engine should be running while you check the fluid, but it’s always best to refer to your owner’s manual. Open the hood and locate the transmission fluid dipstick, which is usually near the back of the engine, labeled, and typically red. Pull the dipstick out, wipe it clean, and then reinsert it fully. Pull it out again to see where the fluid level is. It should fall between the "min" and "max" marks. Healthy transmission fluid is pinkish or red and should not have a burnt smell. If the fluid appears dark or smells burnt, it may need to be replaced. Keep in mind that not all vehicles have a dipstick for checking transmission fluid. Some modern cars require a professional technician to check the fluid using specialized tools. If your vehicle doesn’t have a dipstick, refer to your owner’s manual for guidance or bring it to a trusted repair shop. If the fluid is low, you might need to add more, but only use the type recommended for your car. If you notice strange noises, slipping gears, or leaks, it’s a good idea to have your car checked by a professional technician. If you’re not sure about your transmission fluid or need help, call us at 972-625-1836 . The team at David's Automotive Repair is here to help keep your car running smoothly.

Your car’s engine produces a lot of heat while it runs, and the cooling system is responsible for keeping the temperature under control. When something goes wrong with the cooling system, the engine can overheat. Common reasons for overheating include: • Low coolant levels : Coolant absorbs heat from the engine. If there isn’t enough coolant, the engine can’t stay cool. • Leaking radiator or hoses : Leaks in the radiator or hoses can cause coolant to escape, reducing its ability to cool the engine. • Broken thermostat : The thermostat controls the flow of coolant. If it gets stuck, the coolant might not circulate properly. • Faulty water pump : The water pump moves coolant through the engine. If it’s not working, the engine won’t get the cooling it needs. • Blocked radiator : Dirt or debris can clog the radiator, making it hard for heat to escape. If your car starts overheating, pull over as soon as it’s safe and turn off the engine. Driving an overheating car can cause serious damage to the engine. Regular maintenance is key to preventing overheating. Have your cooling system checked by a technician during routine service to make sure everything is in good shape. If your car is overheating or showing warning signs like a rising temperature gauge, steam from the hood, or strange smells, call us at 972-625-1836. The team at David's Automotive Repair is here to help keep your car running cool and safe.

Most car batteries last about three to five years. How long yours lasts depends on things like the type of battery, how you drive, and the weather where you live. For example, very hot or cold weather can wear out a battery faster, and short trips might not give the battery enough time to recharge fully. Some signs that your battery might be wearing out include your engine starting slowly, headlights looking dim, or a warning light on your dashboard. If you see any of these problems, it’s a good idea to have a technician check your battery. To make your battery last longer, drive your car regularly, don’t leave the lights on when the engine is off, and get your battery checked during regular maintenance. If you’re not sure how your battery is doing, call us at 972-625-1836 . The team at David's Automotive Repair can test it and replace it if needed to keep your car running great.

The torque converter also lets your car stop without turning off the engine. It uses fluid to send power instead of a clutch, which is used in cars with manual transmissions. With a bad torque converter, you might notice slipping gears, weird noises, shaking while driving, or lower gas mileage. Ignoring these signs can lead to bigger and more expensive transmission problems. Getting regular check-ups can help find torque converter problems early. A trained technician can check if it needs fixing or replacing to keep your car running well. If your car isn’t driving right, call us at 972-625-1836. The team at David's Automotive Repair is ready to help keep your car in great shape.

Struts are a part of your car’s suspension system, helping to absorb bumps and keep your tires in contact with the road. They work with other parts to provide comfort and control while you drive. When struts wear out, you might notice your car feels bumpy, takes longer to stop, or makes clunking noises. Worn struts can also cause uneven tire wear and make it harder to steer. If these signs are ignored, they can lead to bigger problems and safety risks. Regular inspections can help catch strut issues early. A professional technician can check your struts to see if they need to be replaced. Keeping your suspension in good shape helps your car handle better and improves your driving experience. If you think your struts might need attention, give us a call at 972-625-1836. The team at David's Automotive Repair is here to help keep your car driving smoothly and safely.

It clears fog or frost from your windshield, keeping your view clear and your drive safe. The defrost works by directing warm, dry air onto the glass to remove moisture buildup. But what happens when it stops working? If your defrost isn’t doing its job, there could be several reasons. A common issue is a clogged cabin air filter, which restricts airflow. Problems with the blower motor or a stuck vent door can also prevent warm air from reaching the windshield. In some cases, low coolant levels or a failing thermostat can keep the air from getting hot enough to clear the glass. Don’t let a foggy windshield put you at risk. If your defrost isn’t working like it should, call David’s Automotive Repair today . We’ll help get you back on the road safely!
