To flush the heater core in a 2000 Oldsmobile Intrigue, first ensure the engine is cool, then disconnect the heater core hoses from the firewall. Use a garden hose to flush water through the core, alternating directions to dislodge any debris. After flushing, reconnect the hoses and refill the cooling system with the appropriate coolant. Finally, run the engine and check for leaks while ensuring the heater operates correctly.
