Ignoring it can lead to more damage and unsafe brakes. Clunking sounds from under the car: This could be a problem with your suspension or steering parts.

How Often Should I Get an Oil Change in Texas?

August 21, 2025
This is especially true here in Texas, where the hot weather puts extra stress on your vehicle’s engine. Most cars need an oil change every 3,000 to 5,000 miles . But this can vary based on a few things: How often you drive short trips or stop-and-go traffic If you tow heavy loads or carry extra weight The type of oil your car uses The extreme heat during the 100 Deadliest Days of Summer adds even more pressure on your engine. Hot weather can cause oil to break down faster, making it less effective at protecting your engine parts. Old or dirty oil can lead to lower fuel efficiency and increase the chances of engine damage. At David’s Automotive Repair in The Colony, we don’t just change your oil. We also check your oil filter and other fluids to make sure your car is ready to handle the Texas heat.

How North Texas Heat Wears Out Your Car Battery Faster

August 19, 2025
The extreme heat speeds up the evaporation of the fluid inside your battery. When this fluid dries out , it can cause corrosion on the battery’s parts. Corrosion and low fluid levels make your battery weaker and shorten its overall life. This can leave you stranded without any warning—especially during the 100 Deadliest Days of Summer, when being stuck on the road is the last thing you need. If your battery is older than 3 years , it’s a good idea to have it tested regularly. Even newer batteries can struggle in the heat, so watch for signs that your battery may be wearing out. Some warning signs to look for include: Engine starts slowly or takes longer than usual Dim headlights or flickering lights Clicking sounds when you turn the key Battery warning light on your dashboard Ignoring these signs can leave you stuck at the worst time. At David’s Automotive Repair, we offer quick and easy battery tests to check your battery’s health. If it needs to be replaced, we can get you a new one fast so you don’t miss a beat.

What’s the Difference Between Testing and Analysis vs. Diagnostics?

August 7, 2025
You may have heard of “diagnostics,” which, to many, just means plugging in a scan tool to read error codes. While that’s a helpful first step, it rarely tells the full story. We believe testing and analysis is a more complete and accurate way to understand what's really going on with your car. Instead of just reading a code, our trained technicians take the time to carefully check your vehicle inside and out. That’s how we get to the real cause—not just the symptoms. Here’s what sets our process apart: We test parts individually , like sensors, wiring, and engine components, to see how they’re performing. We inspect for wear, leaks, or damage that a scan tool won’t catch. We analyze how each system functions and interact with other systems. Why does this matter? Because many problems have more than one cause. A code might suggest one issue, but without testing and analysis, you could miss something else—or fix the wrong thing entirely. Our approach helps ensure more accurate repairs, fewer repeat visits, and less time and money spent in the long run. Whether your check engine light is on, your car is making a strange noise, or it’s just not driving like it should, trust our team to take the time and do it right. Call 972-625-1836 today to schedule your testing and analysis. We’re here to keep your vehicle—and your family—on the road with confidence.
