Truck Cooling System Repair
Overheating diagnosis, radiators, water pumps, thermostats and fan clutches.
Texas heat is unforgiving on a loaded diesel. An overheating engine is not a problem to nurse to the next exit — sustained high coolant temperature can cause damage that turns a hose or thermostat job into an engine job.
LS Truck Repair diagnoses overheating complaints and repairs the cooling system components responsible, whether the cause is a leak, a failed water pump, a stuck thermostat, a fan clutch that is not engaging or airflow blocked at the radiator and charge air cooler.
