Serpentine Belt and Tensioner
A worn belt starts chirping in the heat. We inspect the tensioner and idler pulleys, then install a new belt and tensioner if needed, verifying proper alignment and tension.

Local service
Proudly serving Lockhart
Lockhart is a historic town with a dense downtown core and spreading residential streets lined with 1920s bungalows and mid-century ranch homes. The hot, humid summers and occasional winter freezes take a toll on batteries, belts, and A/C systems, while the flat terrain and clay soils mean dust and mud are part of the job. Many residents commute to Austin or San Marcos, so cars need to be dependable for longer drives.
Our crew drives over from San Marcos in a fully stocked service van, ready to handle repairs in your driveway, at your workplace, or on the street. We work clean, using mats and catching every drop of fluid, and we respect your property. Since we're local to Hays County, we know Lockhart's layout — from the courthouse square to the outskirts along Highway 183 — and we can usually get to you within an hour.
Advanced Auto Mobile Mechanic works across San Marcos, TX & the surrounding Hays County area, so a crew is never far from Lockhart. Call (512) 618-8875 or request a free estimate and we’ll come out and take a look.

What Lockhart homeowners call us for
Brake Inspection & Repair
Lockhart's older neighborhoods have narrow streets and tight parking, which means frequent stop-and-go driving. We check pads, rotors, and calipers, replacing worn parts to prevent noise and fade.
A/C Repair & Recharge
Texas summers in Lockhart demand a working A/C. We test the compressor, check for refrigerant leaks, and recharge the system to factory specs, ensuring you stay cool on the commute.
Engine Diagnostics
Older vehicles in Lockhart often throw check engine lights from aged sensors or vacuum leaks. We scan the computer, interpret the codes, and trace the issue to the failing component.
Oil Change & General Maintenance
Regular oil changes keep engines running in the heat. We drain the old oil, replace the filter, and inspect belts, hoses, and fluid levels, noting any upcoming needs.
Typical projects
The kind of work we take on in Lockhart
Battery Replacement and Load Test
A slow crank on a cold morning often means a weak battery. We load-test the battery, clean the terminals, and install a new one if it fails, then check the charging system.
Check Engine Light Code Reading
The light comes on during a commute. We connect our scanner, retrieve the code, and explain whether it's a simple fix like a loose gas cap or something more involved.

Where we work
Across Lockhart
Downtown Lockhart
Around the courthouse square and along Main Street, parking is tight and streets are narrow. We work curbside or in small lots, careful not to block traffic and using wheel chocks on sloped pavement.
The Historic Residential District
Homes off San Antonio Street and Blanco Street have deep lots and long driveways. We set up in the driveway or on the side street, mindful of low-hanging oak limbs and uneven concrete.
Highway 183 Corridor
Businesses and newer subdivisions along 183 need quick service. We meet customers at their workplace or home, handling battery swaps and belt replacements in parking lots or driveways.

“I can’t say enough good things about Cliff! My daughter’s Mini Cooper developed a problem, and anyone who knows Minis knows they can be challenging to diagnose and work on. Cliff was able to quickly troubleshoot the issue, accurately diagnose the problem, and get it repaired much faster than I expected.”

“Cliff was the most helpful auto mechanic I've ever worked with. After getting a quote at another mechanic in San Marcos at $2700, I wanted a second opinion. Cliff picked up the phone at 8 pm and instantly was helpful. He worked to get me the absolute best prices for the part that was needed.”
