Cooling System Service in San Marcos, TX

About This Service

Cooling system service includes coolant flush, radiator inspection, hose checks, and thermostat testing. Prevents overheating, maintains optimal engine temperature, extends engine life, and improves overall performance and fuel efficiency.

Coolant degrades over time — its corrosion inhibitors deplete, pH drops, and it becomes acidic, attacking aluminum components, water pump seals, and radiator cores from the inside. A cooling system service drains the old fluid, flushes the system, and refills with fresh coolant at the correct concentration. We also inspect hoses, the radiator cap, and thermostat operation to catch problems before they cause overheating.
