Heater Core Inspection, Leak Diagnosis & Replacement Guidance.
The heater core is a small radiator-like component inside the dashboard that uses hot engine coolant to warm the cabin.
When it leaks, clogs, or fails, you may lose heat, smell coolant inside the vehicle, see fog on the windshield, or notice coolant disappearing from the reservoir.
Heater core problems are closely connected to the cooling system. Georgia Fuel & Treats can inspect coolant level, hoses, leaks, overheating history, heater performance, and related cooling system concerns before recommending replacement.
