Diesel Service in New Braunfels, TX

Our Commitment to Excellence in Diesel Service

Diesel engines are powerful workhouses built to last for hundreds of thousands of miles. As with any car or truck, regular diesel service will keep you towing and climbing at your best for the long haul. It’s important to know who to trust for any type of diesel repairs and maintenance. Frank’s Automotive operates shops in San Marcos and New Braunfels, serving diesel owners from Canyon Lake to Seguin and beyond. Locally owned and operated, both well-established service centers employ total car care specialists who deliver precise workmanship on nearly all diesels, foreign and domestic. At Frank’s Automotive, we strive to demonstrate our commitment to excellence in diesel service.

Your Diesel Service Alternative at Two Locations

On Ford Power Stroke and Mercedes-Benz BlueTEC engines just the same, timely diesel service ensures ongoing reliability. It’s safe to assume you’d like to spend your money wisely, and there’s no reason to visit an expensive dealership. Frank’s Automotive is proud to be your affordable dealer alternative for diesel service, where we utilize modern technology, continuing education and comprehensive expertise as a digital shop. Thanks to two fully equipped facilities— in San Marcos since 1999 and at our collision center in New Braunfels since 2010— diesel service is easier than ever. Our experienced crew is ready to get to work on your diesel at either location.

Informed Diesel Service Decisions

There’s much more to good diesel service than correcting an immediate problem, including an extended diesel health plan to help avoid surprises. Our thorough digital inspections, complete with photos, will provide all the information you need to make your own informed diesel service decisions. You’ll know now and in the future exactly what your diesel requires in terms of overall maintenance, whether there are electrical system issues to monitor or there’s a small fluid leak to watch. In any case, we’ll never pressure you to pay for repairs that can wait. From start to finish, the teams at Frank’s Automotive in San Marcos and New Braunfels have you covered every step of the way.
