Understanding Heating System Diagnostic Services at Sunland Tire
Your vehicle’s heating system works by absorbing excess heat from the engine through a mixture of water and antifreeze, known as coolant. Hoses carry this coolant from the engine to the radiator, where heat is expelled. The heated coolant is then circulated to the heater core in the dashboard, where warm air is directed into the cabin of your vehicle. This process relies on the heater hoses transporting the coolant to the heater core, where it transfers heat into the cabin. The system includes key components such as the heater fan, water pump, thermostat, heater hoses, and heater core, which work together to regulate both the engine’s temperature and the warmth inside the vehicle. The water pump moves coolant through the engine block, and from the cylinder heads to the heater core, where the heater fan directs warm air into the cabin. Once the heat is transferred, the coolant returns to the water pump to continue circulating. During a heating system service, our technicians will inspect all components to diagnose and identify the issue.

Why Choose Sunland Tire for Heating System Diagnostic Services?
Heating system issues can arise from both mechanical and electrical problems. For instance, stains under the passenger side of the dashboard may indicate a coolant leak, often caused by a corroded heater core or cracks in the heater hoses. Some heating system problems may be difficult to pinpoint, which is why a diagnostic check is essential. During our heating system diagnostic, our technicians will inspect the heater core, blower motor, heater control valve, water pump, thermostat, and other relevant components. We’ll also check coolant levels, examine heater control valves, and troubleshoot the blower motor. By the end of the diagnostic process, we’ll have identified the issue, made any necessary repairs, and restored full functionality to your heating system. If your heating system fails, don’t hesitate to give us a call or contact us online.
