Diesel Engine And General Truck Repair In Austin, TX, & San Antonio, TX

Not every truck issue starts with the engine. From strange noises and warning lights to handling problems or poor performance, there’s a lot that can go wrong. That’s why we offer complete diesel engine and general truck repair in Austin, TX to tackle anything your truck throws your way.

Engine trouble often starts small. Maybe you’ve noticed reduced power, increased fuel use, or strange sounds coming from under the hood. These can point to issues with your electronic control module (ECM), fuel injection system, or other engine sensors. Our technicians use advanced engine diagnostics to track down the source fast.

Beyond engine work, we’re ready to help with general truck repair, covering everything from electrical issues to steering and suspension concerns. Whether it’s a cylinder head gasket, timing belt, or rod knock, we have the tools and expertise to get it done. We also handle oil pan repairs, engine overhauls, and flywheel replacements when bigger fixes are needed.

If your truck’s performance has dropped or it just doesn’t feel right on the road, let us take a look. We work hard to keep your truck running safely and efficiently, no matter what’s going on under the hood or elsewhere.

"William is a awesome guy. He did a great job. Called about the tandem axle not sliding and helps me fixed some other little issue. I definitely recommend austin fleet services"

Jackson Epalle

"These guys are great, had an emergency with a DEF pump on a black Friday, only shop that picked up the phone, took my driver in immediately and didn't give me the runaround like most do now. I asked not to diagnose anything and just change the pump. Truck back on the road in 3-4 hours and saved us at least 3 days waiting for another shop to open. Definitely coming back here next time our  trucks are in the area!"
