The heater core is a small radiator located inside your dashboard that provides heat to the cabin. Hot engine coolant flows through the heater core, and a blower fan pushes air across it to warm the interior. When the heater core fails, you may experience no heat, a sweet coolant smell inside the vehicle, fogged windows, or coolant leaks on the passenger floor.
Know when your 3500 heater core needs replacement:
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.
