Comprehensive Cooling System Services


Complete Coolant System Inspection


Our thorough cooling system inspection examines every component that keeps your engine cool. We check coolant levels and condition, inspect hoses and connections for leaks, test the radiator cap and thermostat, and evaluate the water pump and cooling fans. This comprehensive approach identifies potential problems before they cause expensive engine damage.


Radiator Repair and Replacement


The radiator is your cooling system's heat exchanger, dissipating engine heat through airflow. When radiators develop leaks, clogs, or damage, engine overheating quickly follows. Our technicians provide expert radiator repair services, including leak repairs, cleaning, and complete radiator replacement when necessary.


Coolant Flush and Fill Service


Over time, coolant breaks down and becomes contaminated with rust, scale, and debris that can damage cooling system components. Our professional coolant flush removes old fluid and contaminants, then refills your system with fresh coolant that provides optimal protection and heat transfer.


Water Pump and Thermostat Service


The water pump circulates coolant throughout your engine, while the thermostat regulates coolant flow based on engine temperature. When these critical components fail, overheating occurs rapidly. We diagnose and replace faulty water pumps and thermostats to restore proper cooling system operation.

Our Cooling System Service Process


Advanced Diagnostic Testing


Modern vehicles use sophisticated cooling system controls and sensors. Our state-of-the-art diagnostic equipment identifies problems with cooling fans, temperature sensors, and electronic controls that affect cooling system performance. We also pressure test the system to locate hard-to-find leaks.


Visual Inspection and Road Testing


Our technicians perform detailed visual inspections of all cooling system components, looking for signs of wear, corrosion, or damage. We also conduct road tests to monitor operating temperatures and identify issues that only appear under driving conditions.


Digital Inspection Reporting


As an AutoTechIQ certified shop, we provide comprehensive digital inspection reports with photos showing your cooling system's condition. This transparency helps you understand what needs attention and make informed decisions about necessary services.


Professional Service and Testing


After completing cooling system work, we thoroughly test the system to ensure proper operation. We verify correct coolant levels, check for leaks, and monitor operating temperatures to confirm your cooling system functions as designed.

Engine Overheating and Temperature Issues


When your temperature gauge reads hot or your engine overheats, immediate attention is crucial to prevent catastrophic damage. We quickly diagnose overheating causes, from simple thermostat failures to complex head gasket problems, and provide effective solutions.


Coolant Leaks and Low Fluid Levels


Coolant leaks can develop in hoses, the radiator, water pump, or engine block. Even small leaks can lead to overheating if left unaddressed. Our technicians locate leak sources and provide lasting repairs using quality parts and proper techniques.


Cooling Fan Malfunctions


Electric cooling fans must operate properly to prevent overheating in traffic or at idle. When fans fail due to motor problems, relay issues, or sensor malfunctions, we diagnose the electrical system and restore proper cooling fan operation.


Radiator and Heater Core Problems


Clogged or damaged radiators and heater cores reduce cooling efficiency and can cause overheating. We provide radiator cleaning, repair, and replacement services, plus heater core diagnosis and repair to restore full cooling system function.
