Chevrolet 3500-Hd-Extended-Cab Heater Core - OEM & Used Parts

Heater core replacement is notoriously labor-intensive because the part is buried deep inside the dashboard. In many vehicles, the entire dashboard must be removed to access the heater core, which can take 4-8 hours of labor. Some vehicles have more accessible designs. Due to the high labor cost, many shops charge $500-$1,500+ for the complete job, making a quality used heater core a smart choice to save on parts cost.
