Trucks do not fail suddenly. They lose control in stages.
What appears as a warning light, a minor leak, or a regen fault is often a system compensating for another failure.
Once compensation begins, downtime is no longer a possibility. It becomes a trajectory.
At Salazar Semi-Truck Repair Inc., we diagnose failure chains, not isolated symptoms.

My husband and I want to thank Pedro Salazar for his professionalism and we are grateful for his honesty. He made my husband feel very confident in the diagnosis of his radiator. He was able to do the repairs the same day and get my husband back on the road. We feel very fortunate to have found his shop. Highly recommended.
Took my truck there for a radiator leak during the Tx deep freeze they had limited resources but replaced it for a good price and had me back up and running in no time.. Very friendly and professional great service will definitely use them again!
Took my Truck there for repairs and the Guy's were very knowledgeable and professional. They changed the Kingpin's in the front end,fixed a coolant leak and alignment. The parts and labor was a fair price. I highly recommend this shop!.
