Texas heat makes engine seals and belts prone to cracking and leaking, which can lead to major engine trouble. We provide the detailed inspections and maintenance needed to protect your vehicle’s longevity. Our shop handles battery swaps and AC repairs to keep you safe and comfortable.
You should service your vehicle every 5,000 to 7,500 miles or every 6 months, whichever comes first, for routine maintenance like oil changes and inspections. Always check your owner’s manual, as some vehicles and driving conditions may require more frequent attention to keep everything running smoothly and safely.
Any of our friendly, neighborhood locations can help you determine the schedule that’s best for your car. In many cases, the maintenance schedule is determined by the manufacturer for optimal service life for your vehicle; this can be found in the owner’s manual.
Appointments are recommended, but walk-ins are always welcome.
Absolutely. We provide clear estimates and only complete the work you approve.
It could be something simple or serious. We recommend a diagnostic scan to find the cause.
After each oil change at Sun Auto Tire & Service, our technician will place a reminder sticker in the upper left-hand corner of your windshield. For added convenience, we can also send you a service reminder when it’s time for your next appointment. To enroll in this program, ask your Service Advisor for details.”
No. In fact, it is against the law for a manufacturer to dishonor their warranty just because the vehicle was serviced elsewhere. As long as the service is performed by capable car mechanics like the ones at your friendly neighborhood Sun Auto Tire & Service, your warranty is valid.
