Flush, Protect, and Prevent: Total Cooling System Care
Your vehicle’s cooling system is critical to engine health. It circulates coolant to regulate temperature, prevent overheating, and protect components like your radiator, water pump, thermostat, and heater core. But over time, coolant breaks down and debris can clog the system—leading to overheating, leaks, or even engine damage.
That’s why we recommend regular cooling system flushes and inspections. At Jefferson Auto Service, we use advanced pressure testing and visual inspections to check for weak hoses, crusted fittings, and small leaks that could turn into big problems. If your coolant is dirty, low, or hasn’t been serviced in years, we’ll flush the system and replace it with the proper mix for your vehicle—restoring protection and performance.
