How do you flush the radiator in a PT Cruiser?

To flush the radiator in a PT Cruiser, start by ensuring the engine is cool, then remove the radiator cap. Place a drain pan underneath the radiator's drain valve and open it to let the old coolant flow out. Once drained, close the valve and fill the radiator with a flushing solution or water, run the engine for about 10-15 minutes, then drain again. Finally, refill with fresh coolant according to the manufacturer's specifications and check for any leaks.
