Comprehensive Car Diagnostics: More Than Just a Scan

At Silva Family Automotive, we started our shop because we recognized the growing need for quality auto diagnostics in San Antonio. Diagnosing car problems is rarely simple, and it goes far beyond plugging in an OBDII scan tool. It requires skill, patience, and a deep understanding of how each component works together in your vehicle.

 

What Is a Car Diagnostic Test?

Think of a diagnostic test as a comprehensive health check-up for your vehicle. It reveals issues that might not show up during a simple visual inspection, helping to catch small problems before they become costly repairs.

During the diagnostic, our skilled technicians carefully examine key systems including:

• Engine performance for inefficiencies or irregularities

• Transmission operation for smooth shifting and response

• Brakes to ensure safety and proper function

• Exhaust system for emissions compliance

• Fuel injectors, ignition coils, and throttle to check harmonious performance

This thorough evaluation can detect minor glitches early, saving you both time and money down the road.

 

Why Regular Diagnostics Are Important

Just like routine medical check-ups prevent serious health issues, regular vehicle diagnostics keep your car running smoothly and efficiently. We recommend scheduling a diagnostic test at least once a year to maintain optimal performance and fuel efficiency.

​

What We Look For During Diagnostics

• Drivability issues: Is your ride bumpy? Does your car rumble at a stop or hesitate when accelerating?

• Transmission problems: Rough shifting or odd sensations when switching gears?

• Brake concerns: Grinding sounds or pulling to one side? Sometimes it’s just alignment, sometimes axles or brakes need attention.

• Unusual smoke or odors: Notice strange smoke from the front or back, or funky smells you can’t explain?

• Worn parts: Belts showing wear, loose wheel play, ignition coil issues, and more.

• Fluid leaks: Spot red, black, brown, orange, or yellow fluids on the ground? We pinpoint the source and urgency—helping you prioritize repairs without stress.

• HVAC problems: Is your AC not cooling or the heater blowing stale air? We diagnose blower motors, leaks, and air pressure issues.

 

Beyond the Basics: Manufacturer Alerts & Vehicle History

Our diagnostic services include access to manufacturer notifications, car history information, and other essential data through our trusted industry partnerships — information typically unavailable to the average driver.

 

Why It Matters

Your vehicle depends on various fluids for engine lubrication, cooling, braking, and more. A leak isn’t just a mess — it can signal a much larger problem. Fluids often give clues through their color, texture, and even smell.

If you start noticing:

• Strange noises

• Reduced performance

• Shaking during stops or driving

• Unusual drivability problems

It’s time for a diagnostic evaluation.

 

Thinking About Buying a Used Car?

A diagnostic test can be your best friend when shopping for a used vehicle. It provides peace of mind and ensures you’re making an informed decision before committing.
