What we handle
Practical service with a diagnostic-first mindset.
A warning light or strange symptom is only the starting point. McKay's Garage uses current diagnostic equipment, hands-on testing and real mechanical experience to find the cause before recommending parts.
- Check-engine and warning-light diagnostics
- Hard-start, no-start and intermittent problems
- Electrical and charging-system troubleshooting
- Sensor, wiring and drivability diagnosis
- Advanced troubleshooting for difficult-to-find faults
Common questions
Does a scan tool tell you exactly what part is bad?
Not always. A trouble code points to a system or condition. Good diagnosis uses the code as a clue, then verifies the actual cause before a repair is recommended.
Can you diagnose intermittent problems?
Yes. Intermittent issues can take more testing because they may not be present all the time, but scan data, electrical testing and a clear description of the symptom help narrow them down.
Do I need an appointment for diagnostics?
An appointment is the best way to make sure enough time is reserved to evaluate the vehicle properly.
