Fast & Accurate Car Engine Troubleshooting
When your car isn’t running right, or if the check engine light is on, you need answers you can trust. At 5M Automotive, we find out exactly what’s wrong with your engine using a clear and step-by-step process.
We specialize in Toyota, Lexus, and other Japanese vehicles, but we work on all makes and models. Our goal is to give you clear information and fix your car the right way the first time.
Our Engine Diagnostics Process at 5M Automotive
At 5M Automotive, we utilize advanced tools to inspect your car’s engine for potential issues. Here’s how the process works:
-
- Full System Scan: We connect your car to a diagnostic tool that reads error codes from the computer. These codes give us clues about what’s wrong.
- Visual Inspection: We look under the hood to check for loose wires, damaged hoses, or anything that looks out of place.
- Live Data Monitoring: While your car is running, we monitor the performance of various components, including sensors and fuel systems, in real-time.
- Component Testing: We test important engine parts to make sure they’re working properly, such as:
- Spark plugs and ignition coils
- Fuel injectors and air sensors
- Cooling System Check: We check the radiator, thermostat, fans, and coolant to ensure your engine doesn’t overheat.
- Test Drive (If Needed): If we can’t find the problem while your car is parked, we’ll drive it to see how it behaves on the road.
- Digital Report: You’ll get a report with photos, videos, and notes from our technician. This report will outline the findings and provide recommendations for resolution.
