The heater core in a 1994 Oldsmobile 88 is a small radiator-like component that allows hot coolant from the engine to heat the air that is blown into the cabin for warmth. If the heater core is leaking, you may notice a sweet smell inside the car, foggy windows, or coolant pooling under the dashboard. Replacement involves draining the coolant, removing the dashboard for access, and swapping out the old core for a new one. Regular maintenance can help prevent issues with the heater core and ensure efficient heating in cold weather.
