Semi-Truck Repair Shop in Dallas, TX Same-Day Diagnostics & Fast Repairs
When a semi-truck breaks down in Dallas, everything stops with it — your route, your revenue, and your ability to deliver on time. Downtime is expensive and usually avoidable. A small coolant leak becomes an overheating engine, a minor air issue becomes a brake failure, and a weak battery becomes a costly no-start.
At Salazar Semi-Truck Repair Inc., our shop is built to diagnose fast, repair correctly, and prevent repeat failures. Fleets and owner-operators across Dallas–Fort Worth rely on us because we fix the real cause, not the symptom — and we do it with speed, precision and honesty.
