To replace the sleeper heater core on a Kenworth, first, disconnect the battery and drain the coolant from the system. Remove the sleeper panel to access the heater core, then disconnect the hoses and any mounting brackets. Carefully pull out the old heater core and install the new one, ensuring all connections are secure. Finally, reassemble the sleeper panel, refill the coolant, and check for leaks before reconnecting the battery.
