Is your semi-truck overheating in Dallas traffic or under a heavy load?
A rising temperature gauge is more than an inconvenience. It's often the first warning before engine derate, lost power, expensive towing, and major engine damage.
The real problem may not be the radiator alone. We've diagnosed overheating caused by coolant leaks, failing fan clutches, weak water pumps, stuck thermostats, restricted radiators, pressure loss, damaged hoses, and other cooling system failures.
At Salazar Semi-Truck Repair Inc., we don't guessβwe use dealer-level diagnostics to find the root cause and repair it correctly the first time.

Every mile driven with an overheating engine increases the risk of catastrophic engine failure and longer downtime. Fixing the problem early is almost always less expensive than repairing the damage caused by waiting.
