What to Expect With Engine Services
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.

Frequently driving your car with little fuel can harm your engine over time because the gasoline at the bottom of your tank is usually the dirtiest. When this part is used for fuel, you run a higher risk of dirt reaching your fuel line and engine.


Signs of Engine Trouble
Catching engine issues early can save you time, money, and major repairs.
If you're noticing any of the following symptoms, don't wait:
- Knocking, tapping, or unusual engine noises
- Excessive exhaust smoke
- Decreased fuel efficiency
- Check engine light illuminated
- Hesitation or stalling during acceleration
These issues can indicate anything from sensor failures to serious internal damage. If you're experiencing any of these signs, schedule an engine inspection at Christian Brothers Automotive Grayson as soon as possible.
